And on to the next dream...

 After finishing the e-bike stretch cruiser it was time to replace the shifters and crank on a beautiful late-1990s Dean. The bike might actually date from right after the turn of the century. We've been seeing it in the workshop nearly every spring or summer for a long time. I built those wheels more than ten years ago. Maybe so long ago that we looked up parts in a printed catalog and placed orders by phone.


The picture above shows the bike after its recent changes. Originally, it had a Campagnolo Chorus crank, Record 10-speed brifters, and Centaur derailleurs. I vaguely recall that we had already upgraded it from 9-speed to ten-speed by the turn of the century, but we did work on a number of Campy-equipped bikes. Campagnolo actually provided instructions for changing some internal parts in a brifter to change the number of speeds. And, of course, the internals were completely repairable. But the shifter bodies and so many internal parts on this bike were now so worn that repair would have cost a lot more than a new set of brifters.

A lot of years had passed, but Campagnolo had always been the leader in backwards compatibility. You can buy quite a few parts for a 25-year-old shifter, although some of them are being phased out. During that 25 years, the parts fit models that spanned more than eight years, which is phenomenal in the post-Shimano era of technological hyperactivity.

The rider wanted lower gearing than the 53-42 chainrings on his existing crankset. Campy's 135mm bolt circle limits how small a ring you can fit, and they have to match that proprietary bolt pattern. Back when Campy's BCD was 144, other manufacturers copied it. Then Shimano and the Japanese makers brought in the 130 bolt circle diameter, and the industry shifted to that. This meant that you could put on the 53-39 combination that became the de facto standard for road cranks for years. You could even get a 38 for the inner ring, but few did.

When compact road cranks came in, they used the 110mm BCD that mountain bike chainrings were using. Mountain bikes still used triple chainrings. Road compact cranks were designed for just two rings up front. While the young and strong would combine the new little 50-tooth big ring with an 11-tooth cog for the hardest one on the cassette, the 50-34 combination that was most common served as sort of a secret granny gear for riders who were starting to feel a little faded as age took its toll.

So many years had passed before the owner of the Dean felt the need to gear down that a nice compact double for ten-speed was tricky to find. I also recommended trying to match the aesthetic of the old steel frame rather than sticking some aerospace monstrosity on there. I suggested, and he agreed, to get a Velo Orange Grand Cru Drillium crankset. It was actually a little more retro than the bike, but it's also fairly affordable and distinctive compared to the monotonous hellscape of soulless modern componentry.

It's actually made by IRD. But Velo Orange has their Grand Cru badge applied to it, and they deserve support for being such a friend to the retro rider.


The owner dropped the bike off in late March, 2024. I was able to get the brifters and bottom bracket right away. The crank was shown as out of stock for a month or so. The customer was willing to wait. That ETA got kicked down the road a month or two at a time, all the way to the end of the year. We nearly lost the job entirely, but I had contacted Velo Orange directly by that time, to confirm that they were still going to have the cranks at all. We got the customer to hang on. The crank finally arrived a week or two ago. We were still in ski mode, so I didn't start the job right away. We were also buried in the stretch cruiser project, which had been plagued with its own spec problems, but those had resolved more quickly.

As I dug into the Dean, I discovered that the slop in the shifters had been masking slop in the derailleurs. They were very floppy. That led me to look at what we could get for Campy 10-speed derailleurs.

Nothing. That's what we can get for Campy 10-speed derailleurs. Not a zippin' thing. Zippity doodah. Zilch. Nada. Campagnolo has abandoned their faithful long-term customers actually worse than Shimano. Shimano at least still makes some 10-speed road derailleurs for mechanical shifting, with brifters to match, for those who are addicted. For the friction shifters, the truly free, we can buy whatever derailleur we like the looks of and can afford. But for the brifter-dependent, the company that launched the industry into technofascism still has a little lifeline hanging out for the laggards still nursing their older stuff.

Funny: fascism was actually invented in Italy, and the Italian company was the slowest to adopt technofascism. But they're racing to catch up now. Be sure to shell out massive bucks for their 12-speed electronic stuff. It's kind of nice to see them back to duking it out for pro team spec, but the game has no soul anymore, so what are we really winning?

Way way back, in the 1970s and early 1980s, you could actually get every part of a Campagnolo derailleur, separately, to replace what might have gotten bent or cracked in a crash or a workshop mishap. It was treacherously easy to strip the threads on a front derailleur swing arm when tightening the cable anchor bolt. Good thing you could buy just the arm, install it, and pledge to use a lighter touch after that. You could also crack the clamp band, tightening the derailleur on the seat tube. Again: press the rivet out, replace the band, put on the new one and be more sensitive, you clod. Do you caress your lover with those awkward, loutish hands?

Well yes, yes I did, which explains my long spells of monkish solitude, but anyway... You can't get parts to rebuild a derailleur anymore. Long gone, though I do recall seeing them as late as the early 21st Century. I'll have to dig into my archive of Quality catalogs. QBP's print catalogs used to provide such complete tech information that we could figure out a lot of repairs and compatibility puzzles just from what they included about each product.

I had recommended that the customer stick with Campy because of their legendary durability and product support. Seems like I should have investigated them a little more deeply before charging ahead with this job. The customer and I were both trying to extend the life of existing parts rather than junk stuff and start over. Now, if he isn't satisfied with how this thing shifts, we have no option that doesn't cost him a chunk of change to take a different tack.



These shifters seem less substantial than they used to be, and the upshift thumb lever impedes removing the rubber hood to mount the brifter or run cables.

They also only fit 4mm shift cable housing, which means that we can't fit them with the easier-running 5mm which cures so many shifting problems.

Just like Shimano, Campy declares that their shifting systems and drive trains have to be completely matched, 11-speed with 11-speed, 12-speed with 12-speed, end to end. While I would be inclined to test them, trying to graft in 11-speed derailleurs with these 10-speed brifters, the lowest priced front derailleur retails for about $60, and they don't even list an 11-speed rear derailleur. So then we're experimenting with a 12-speed rear derailleur costing more than $200. Or we go on the hunt for good used, and new old stock.

If we talk him into friction barcons, he either eats the cost of the 10-speed brifters and buys some nice brake levers on top of the barcon price, or he uses the brifters as brake levers only, which looks kind of weird and accentuates our defeat at the hands of the technofascists. And all of this is just so that we can graft in whatever derailleurs he wants to try. Whatever derailleurs he wants to try includes pretty much anything on the market if he shifts in friction. They just have to have the gear range and chain capacity to match what he has. And friction shifters will be much more forgiving of the slop in the old derailleurs. He could just keep running those until they totally flop off.

I'm insanely loyal to old machines that I've grown to love. Aided by my own mechanical knowledge, friction shifters, and access to parts, I will keep my own stuff going for decades. I provide the same service to any customers or friends who want to cultivate and maintain the ancestral riding skills. It bums me out deeply when a customer decides to euthanize an old bike because they fall for the lure of the new and exotic, or just decide that something old isn't worth spending money on. I can't afford to rescue any of them, let alone all of them. And I always feel guilty if my enthusiasm for bike immortality and persistence in the face of a challenge leaves them with a result that they're not delighted with.

The industry makes it increasingly hard. Any of us interested in the deathless bike need to pay constant attention to keep track of something that might have been replaceable that has now turned into a vital organ to be preserved. Friction shifting can cover a lot of situations, but it can't work around systems that the industry completely abandons, like certain chainring sizes, or cassettes for proprietary freehub bodies. I'm looking at you again, Campy. While it's contemptible on one level that the entire rest of the industry adopted Shimano's Hyperglide spline pattern, it does create a de facto cassette standard that makes mix and match a lot easier.

I do have a Campy-equipped carcass in the shop basement that might yield donor organs, but it might be 9- or even 8-speed. It's that old. I have defended it against many a clutter purge over the years. Vindication would be sweet. I'm not into losing to the industry and the throwaway mentality.

Another day, another bike I'd never heard of

It was too new for Classic Rendezvous, but still from the "screwed and glued" aluminum era. Its worn decals seemed to say Prism, but a web search on Prism bikes, bicycles, cycles turned up nothing that resembled it.

Little letters on the frame and fork said SR Litage. That seeming subtitle brought up the bike and its kin from the late 1980s.




 Componentry said early 1990s to me. Later the owner told me she got this one in 1993. That headset looks particularly annoying to adjust and keep set. Crap like that is a large part of what made threadless headsets seem like a good idea. I was glad that the bike wasn't in for a full tune. It only had a shifter problem with the 8-speed Campagnolo Ergopower brifters. They were jammed.

The bike had a weird mix of parts: Campy drive train and rear hub, Shimano Ultegra brakes from back when they still said "600," and that Mavic headset. ITM bars. The rear brake cable enters the frame, but the housing is continuous. Shift cables are external. Shift housing stops are mounted to downtube shifter bosses.

I figured that the shifters had jammed because the index springs had broken and fragments had wedged in the ratchet rings. I detached the cables from the derailleurs to see if I could free anything up. The shifters then pulled the cable perfectly well, with no crunching or excessive play. Maybe the derailleurs themselves were stuck.

Nope. I could move them easily by hand.

I reconnected the cables and everything worked perfectly. So I test rode the bike. It didn't want to shift to the big ring. Then it dropped the chain inside, where it stuck behind the tabs on the inner ring. I carried the bike back inside to pull the crank and extricate the chain. This led me to discover that the bottom bracket was unscrewing itself. An early cartridge model, as it migrated to the right it pulled the left side in after it. The cartridge never felt loose as the crank migrated sideways away from the front derailleur.
It hadn't gone far enough inside to pull the left crank arm against the chainstay on the way around.

An exploded view in one of our old Campy parts catalogs showed the Athena bottom bracket with what look like serrated washers that are supposed to go in the cups on either side. I would presume that these are supposed to enhance the grip of these unflanged cups against the cartridge with the bearings in it so that they can be securely torqued into the bottom bracket shell. The axle also measured shorter than the triple crank supposedly requires, but the chain line was almost too far out, even with the BB restored to its proper position. I torqued it as securely as I could. The only way to get those missing washers would be with a time machine.

In eternity, all nows are equal. Every moment exists and could be reached if we were not stuck experiencing time in a linear flow. I think of this every time I look through our old Quality catalogs at all the componentry I wish I'd stocked up on.

If I had needed to open up the shifters I would have removed them from their clamps and worked on them off the bike rather than unwrap the bars and lose the vintage Celeste green cork wrap. Even if it didn't have aggressive adhesive backing, so I could get it off without shredding it, it never lines up exactly the same. The shifters seemed miraculously cured, as if they were only trying to get the rider to bring the bike in to have the bottom bracket apprehended before it escaped completely. If they malfunction again, we do keep index springs on hand. Campy being Campy, they still use the same springs in the same basic design.

The season of cabbage and caffeine

As bike commuting mileage drops, and other activities don't seem to fill in like they used to, I shift from using brown rice under a lot of my slapped-together meals, to using sautéed shredded cabbage instead. Shred it fine, and cook it over medium-high heat in a little oil (your choice) with some onion and seasonings you think you'll like. In another pan I cook up whatever meat and vegetables I would have slapped onto -- or mixed with -- the rice. Separate pans work out best for the quantities I try to make, because I make enough to get a supper and two or three lunch-size portions of leftovers. A grab and go container for lunch helps speed me through my typical morning stumble toward the door.

As daylight drops, my energy drops with it. During full bike commute season, I limit my morning coffee to avoid having to stop en route to release excess fluid. I might or might not have a little jolt in the afternoon. Once we get well into October I feel like crawling into a burrow. I certainly don't feel like vaulting out of bed. I'll drain the morning pot of coffee and definitely seek it in the afternoon. Any of y'all who can get by on spring water and meditation have my admiration, but that's it. I'm sure it's great.

The growing season ends with New England's well-known psychedelic splurge as deciduous trees withdraw chlorophyll from the leaves they are about to shed.


At summer's end, we get a rush at work, of people who waited until summer was over so that they could avoid the rush. We also get people who were holding off as long as they could, to keep riding in the prime season. Thus cash flow drops precipitously, but wrench work and brain teasers actually intensify.

This recumbent had tire and drive train problems. Once I got it back together, I found it basically unrideable.
Everything was hooked up right. I just couldn't get it to balance well at all. It resisted that first pedal stroke to establish forward motion, and wanted to flop over immediately. This was true in any gear. It was super twitchy. It was actually a late summer arrival, but I never had time to include it in a blog entry.

Then came someone's swamp buggy.
We'd replaced the chain previously. It hadn't skipped on a test ride, but it did skip when the owner rode it in the swamp. He brought it straight back to have the cassette replaced.

The owner of this Trek Y bike from the 1990s had a hankering to try riding again. He's a classic Van Winkle. Van Winkles are the people who have been asleep for twenty years and awaken to find the world much different than the one they dozed off from.
It doesn't help that he bought the bike used from a shop owner who was a trendoid. The bike had all the cool shit from 1998, including the Rapid Rise rear derailleur. I did learn from Sheldon Brown's website that, prior to Campagnolo's invention of the parallelogram derailleur, all spring-loaded derailleurs were "low normal," meaning that they used the return spring to pull the chain toward the low (largest) rear cog rather than down toward the smallest cog. It should tell you something that Campy's introduction of the high normal parallelogram derailleur established the design that the entire industry followed until Suntour introduced the slant parallelogram derailleur in the 1960s. Even after that, the basic parallelogram remained more common until well into the 1970s. According to Sheldon Brown, other companies didn't jump on until the expiration of Suntour's original patent in 1984, but I know that Shimano was already making slant parallelogram derailleurs before that. But they've always been aggressive competitors, not above pushing the envelope of decency, not to mention legality. They got slapped for it in the 1990s when it became too egregious to ignore. Nice guys finish last.

A happy couple of tourists brought their matched Sevens in for examination and any necessary repairs. They do well with their regular home care, so the bikes needed little. I did change the bridge wires on the rear cantilever brakes, changing the stock ones that were too short for longer ones that provided a firmer lever feel.

Another tourist, coming out of a long layoff, brought his vintage 1980s Trek for a full overhaul and upgrades to prepare for a long haul continental wander, perhaps next summer. He has laid out a route that would keep him in a 72-degree average daytime temperature the whole way along a meandering route that works with both latitude and altitude to hit the desired temperature. We discussed all his options, from total replacement with a Long Haul Trucker to full restoration on the Trek. Because the Trek was an old friend, and some of us are sentimental that way, we went that way.

The bike had been fitted with new wheels. The crank had been replaced because the original one broke. The bike had been built for 27-inch wheels, and the shop he went to had replaced them with 700c. The crank was a TruVativ, and rather cheesy.

I've put 700c wheels on bikes designed around 27-inch, but only with caliper brakes. You just get a longer brake if the one that's on there does not have sufficient range to lower the pads to the smaller rim diameter. I hoped that we could replace his old brakes with something more accommodating.
The mountain bike era began using brakes like these Dia Compes. Technology advanced rapidly with higher demand, leading to brake arms that allowed for pad height adjustment as well as every other angle in alignment. But you're limited by the immovable placement of the post itself. If it's low enough, you can use a modern brake to get the pad in range with good alignment to the rim. You can see here that the mechanic who made the wheel swap years ago just angled the pads down because that was all he could do. He didn't built the guy a decent 27-inch wheel, even though there were rims available. Do it cheap, don't do it right. Right?

I ordered some linear pull brakes and the drop bar levers designed to go with them, hoping that the range of vertical adjustment would make it work. I also built the guy some 36-spoke wheels with wider rims to replace these 32s with Mavic MA2s. The MA2 was a nice enough rim in its day, but narrow for a wider touring tire. I've been getting good service out of Sun CR18s. Not only does the wider rim support the tire better, it moves the braking surface closer to the brake arm. I hoped that the combination of factors would allow the use of 700c wheels.

I could have gotten 27-inch rims for the new wheels, but the selection of rubber in 27-inch isn't as good. It's a crap shoot these days. When I geared up for touring around 1980, and when this guy did just a few years later, 27-inch seemed like the better choice for touring in North America, because 700c had not taken over. Performance clinchers themselves were fairly new technology. We figured that you could probably find a 27X1 1/4  just about anywhere at that time. Now, though, you're more likely to find a dedicated bike shop in the hinterlands, and 700c has become the road/hybrid/gravel norm. You can't plan for every contingency.

I also dug up an old mountain bike crank for the bike, with nice forged arms and 5-bolt chainrings. Things were coming together. But the brakes weren't going to work. Those mounting posts were just too high. With the pads all the way down, they still had to be angled down to get anywhere near the rim. And it wasn't near enough.

After consultation, the customer decided to go with a Surly Long Haul Trucker frame, onto which I would put all of the upgrade and restoration parts. The crank I found for him is the same model I have been using since 1992, when it started out on my Stumpjumper, then moved to the Gary Fisher frame with which I replaced the Specialized, and later went onto the Surly Cross Check I've been riding since 2000. It's one of the few accidentally durable things made by Shimano. It probably helps that I'm not much of a sprinter. Even chasing a truck draft I seldom get out of the saddle.

Into this whole lineup of touring bikes came a near-neighbor of mine (less than 4 miles apart is right next door in rural areas) with his 1970s Raleigh Competition. He's another person who "used to work in a bike shop" and is still enjoying the swag.
It's all Campagnolo Gran Sport, with the less-common three-bolt crank.

The handlebars, a solid 40+ years old, are bent down slightly on one side. That's a bad sign, considering that the handlebar industry recommends replacement every three years. We all know that expiration dates are mainly designed to get you to buy more stuff, but I have seen older handlebars snap off next to the stem after two or three decades. When they outright droop it's a good hint that you might want to renew that particular critical piece. Other than that, the job is just a straightforward  overhaul and some tires from this century.

Into the midst of all this archaeology come the day-to-day weird jobs like this John Deere pedal car with the cranks falling out.

Hell has nine circles. So does this thing.

The pulling threads on the right side are twice as deep as normal, for no discernible reason. But the fun doesn't end there. The threads were also buggered in a way that made it impossible to get the crank puller to thread in at all. This is after I had to remove absolutely every piece of shrouding from the fully enclosed drive train to undo every nut and bolt to take tension off the chain.

I removed the left crank arm and slid the BB out through the right side, since it was falling out that side already. Then I braced the right crank arm in the vise so I could gently and precisely persuade the  axle to drop out of the crank arm, using a drift and a small sledgehammer.

The BB is mounted to a bolted-on bracket that was attached backwards to the frame, so that the BB cartridge couldn't be installed the right way around. Normal use would unscrew it from the frame. I unbolted the mounting bracket and reinstalled it the right way around. The people who assembled this thing clearly did not understand its bike-derived components at all. And I don't know how they ever got the chain on it, because I had to add a half-link just to get it onto the sprockets.

Speaking of not understanding bike parts, this has been the year for people putting the pedals in the wrong crank arms. When it won't go in straight and it's binding up like a bastard, why do you keep graunching on it? But they do. Then I get to extract the pedals -- if they haven't fallen out of the stripped-out holes already -- and either re-tap or replace the crank arms. One of those cases came in just last week. It's one of those repairs where you can't really give an estimate without trying to fix it first, to see if there's enough metal left to tap.

Still in the crank and pedal department, one of the local riders is a lad -- now an adult -- who spends hours a day riding all over town on whatever mountain bike he is putting to the test at the moment. He isn't an official product tester, but he definitely puts them all through the wringer of long, continuous use. He's not a jumper or a sprinter. He just goes. And goes. And goes. When he finally brings a bike in because the gears skip or the shifting is funky, we'll discover something like the bottom bracket shell completely broken loose from the seat tube. Worn-out chains are just par for the course. It's the special touches that elevate it from the mundane. This time, his chain had fallen off the front, and neither he nor his father could get it back on. Something was jammed up. Well I guess so.

He was "just riding along." The crank arm bolts are tight. Something inside ain't right.

And there it is:
The axle is snapped right off. At least it's a simple fix. We plugged in a new BB cartridge and off he went again.

Trainee David wanted to adjust the bearings in his XT pedals before an upcoming 'cross race. I helped him figure out how to get in there.

Modern bike componentry comes in two forms: stuff you can't take apart, and stuff you can take apart that will make you wish you hadn't. This is the latter. Of course you can find chirpy forum posts about how easy and fun it is, from people who claim to do it every one month/six months/year, but it's seldom more obvious that no manufacturer actually wants you to fix anything than when you try. The left pedal has some irreducible slop in it, either from a worn (not readily available) bushing or from the loss of an equally unavailable rubber seal. The rubber seal shouldn't be structural. None of the forum chirpers refer to it as load bearing. But David's has vanished somewhere in the vastness of the New England cyclocross circuit, and now the pedal clicks and wiggles no matter how tight the adjustable bearings are. The metal bushing is present, and looks about the same as the one in the right pedal. The pedal shaft itself is a bit worn, possibly from riding too long with a loose bearing. But the right pedal bearings were equally loose before we adjusted them, and that pedal is tight and smooth now. The only obvious difference is the lack of the rubber seal in the left one. And you can spend hours poking around on the Internet to see if anyone really knows, without ever finding out for sure.

The Campy Gran Sport pedals on the old Raleigh are classic cup and cone bearings. Campagnolo Record pedals were so securely closed that they would run smoothly for years. On that level of Campy, pedals and bottom brackets had a reverse threaded section that expelled dirt as you rode. They didn't do it on the lower models, but you're still not dealing with microscopic bearings sitting in an almost imaginary race. Step-in pedals have higher cornering clearance and other added values for the competitive rider. We've all been trained to beat things up and wear them out rather than keep them going through years of appreciative, moderate use. Repair attempts these days are usually just a preamble to justify replacement. You keep it up as long as you can afford it.

These are the darkest nights, even though they are not the longest. The trees have not entirely gone bare, so the forest shadows are dense black. These are the spookiest nights as well. Half naked trees raise bony arms against what you can see of the sky. Any wind makes the branches creak and rattle like a marching skeletal army, while dry leaves skitter like rats on the forest floor you can barely discern even with a good light. The sight of another person sparks a moment of misgiving rather than sociability. What's anyone doing out here now? Only a weirdo would be out in the woods in the dark. You guzzle some caffeinated courage before heading out on the lonely ride toward home.
