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.

Hydraulic Fracturing

El Queso Grande texted me on Tuesday night to say that the workshop was slammed and that several sets of hydraulic disc brakes awaited my healing touch. The repair shop continues to challenge my intellect while depressing me in general. I keep thinking that if I was a real mechanic type, sucking on a Gauloise and not giving a shit about actually riding, I could simply take pride in fixing whatever was dumped in front of me. Or if I was young and smitten with the technology -- or not young and still smitten with the technology -- I would still feel like I worked in the candy store. 

Given the choice I'd take the Gauloise. It reflects my attitude toward the consumerism and the subcultural tribalism that has fractured riding. Less than once a year something comes through the shop that I might actually desire. In truth, all I really desire is to keep my personal bikes rolling in their present form, and be able to replace each as necessary with something as close as possible when the time comes.

Just as the perfect metaphor for consumer goods marketing is cocaine, the perfect metaphor for any service occupation is sex work. Certainly in my case, I now have to handle a lot of fluids I don't want to, and stick things in places I'd rather they didn't go.

I mean brake fluid and internal cable routing, of course.

Speaking of internal cable routing, a local rider was in a crash when last Sunday's group road ride literally ran into a couple of dogs on a back back road in Ossipee. Riders have snapped forks hitting a squirrel, but this guy managed to get halfway over a Jack Russell terrier before the chainring stopped everything. The rider was banged up but able to continue the ride to get back to Wolfe City. (We haven't heard a report on the dog.) He brought me the bike to check over. His wheels needed truing. His bar tape was shredded on one side. We would check any frame and fork carefully after a crash, but with carbon fiber the stakes are higher. Because carbon is an all-or-nothing material, any crack is a serious crack.

Everything seemed remarkably good. Maybe it would have been worse if he'd hit a squirrel. I put the wheels back on and ran it through the gears. The front derailleur was rubbing the chain on the big ring. The rear derailleur was imprecise. I snugged the cables up. Things were better, but not quite perfect enough. Drive trains with 10 and 11 speeds are very sensitive to minor inaccuracies. Electronic shifting avoids the problems of cable-actuated mechanical systems, but introduces its own set of problems.

With internal cable routing, you don't get to see much of the cable. This creates the mistaken impression that the cable is protected, when it is really just inaccessible. Everything looks so clean, so aerodynamic. But what you really have are a bunch of little holes into the interior of your frame. It's a Roach Motel for dirt. Dirt makes shifting unreliable.

I turned the bike up in the work stand to check the bottom bracket cable guides. They're the Achilles heel of internal cable routing systems.
At the very bottom of the bike, closest to the ground, the cables emerge from their little tunnels to be routed to the front derailleur through a short little tube, and to the rear derailleur through a longer sewer. Any attempt to clean this area will simply drive little dirt ninjas deeper into the interior of your frame. Your best chance is to change the cables completely, which is a time consuming and finicky task with internal routing.

I blew dirt away with a lateral burst of air from the compressor. Depending on Bernoulli to help me out, I have used directed air on numerous occasions to suck dirt away rather than blow it in. But under the bottom bracket you have openings in at least two directions at odd angles, so you can't really blast away with any method. Or you can try the shop vac.

The shifting seemed acceptable after all that.

The day had started with one brake job after another. The owner of the first bike had taken his wheel out and then squeezed the lever. He'd managed to pry the pads apart and put the wheel in, but said that the brakes didn't work. Every brake job gets written up as a bleed these days, but after I reset the pistons and cleaned the pads and rotor it seemed to be working fine. The gears were a different story. The bike is a Rockhopper 29er, just old enough to have external cables, but they're in full-length housing. The SRAM rear derailleur didn't want to fold up enough to drop the chain onto the hardest cog. Fine silty dirt and a few crashes have stiffened up the pivots so that the return spring can't retract the parallelogram completely. And fully housed cables aren't really better protected from contamination; the housing seems to produce more drag than shelter.

Next up was a double bleed on a Specialized Stumpjumper 6-Fattie that really emphasizes the evolution of mountain bikes into motorless motorcycles. On the plus side, it had SRAM brakes that take the Bleeding Edge tool, which does seem to make the process somewhat easier. I think I only had to redo the rear brake once. The pads were worn an ambiguous amount, so I put in new ones, which stiffened up the lever feel even more. Because I never get to work without interruption, meticulous procedures take even longer.

One interruption came from a customer who had brought his Orbea Orca to have a skipping problem checked out. The chain was so worn, it skipped on the derailleur pulleys. Changing chain and cassette seemed to set things right, but then he rode it and had more problems. I explained that we would ordinarily have started with cables and housing, but that the chain issue had seemed obvious, and cables and housing would have meant stripping off his sexy bar wrap. I'll sacrifice what's necessary to get a job done, but since the look of the bike was obviously important to him I didn't want to shred the cosmetics unnecessarily. Then, as we were examining the bike in the parking lot, we turned it over and found a crack in one chainstay. This was probably not the cause of the chain problems, because the ding from which it originated was small and fairly fresh. The bike did not flex or make scary noises. He's pursuing replacement through Orbea, and came in to discuss riding position and fit issues. That's never a short conversation.

The last brake bleed had to wait until this morning. The bike came from Bikes Direct to the Repair Shop. I assembled it in early July. The rear brake calipers are already a rust pit.

The bike has SRAM Guide R brakes, nominally the same as the ones that behaved reasonably well on the previous day's Stumpjumper, but these have conventional bleed ports. That calls for a slightly more cumbersome procedure, but I've done it before. The wrinkle this time is that the rider and his buddy tried to bleed the system themselves before giving up and bringing us not only their original problem but the results of whatever they had done.

The lever was whacked out. We had to reposition a couple of parts just to set it up according to the instructions to begin the actual bleeding. I'm not sure how they got things as jammed up as they did, but I could not get fluid to go through the system no matter what I did. I finally faced the fact that I was going to have to open up the lever to see why the piston did not want to move.
This isn't all the parts. The real business was still stuck inside the lever body.
Supposedly, when you take out a spring clip and a washer, you can reach in with the tippy tips of needle nose pliers and extract that piston. I couldn't get it to budge. I tried everything, even things that will put your eye out if you do them wrong. Eventually I was able to poke something through from the brake line end of the lever and push the piston out, but it's a very stiff fit. And between whatever they did, and what I had to do to get it out, it ain't going back in.

Of course all parts for this lever are out of stock for at least three weeks.

So there went a couple of irreplaceable hours of my life. I spend most of my time now working on equipment I would never advise anyone to buy, for a riding style that doesn't interest me in the least.

Motorless motorcycles.

If anyone ever did all the maintenance that the fine print tells them they should, they would never have time to ride. But biking is supposed to be cheap. The biggest expense is the bike, right? They're cheap to fix. There's no motor. How hard can it be?

The owner of the Stumpjumper asked me, "Is it a real pain in the ass to work on these things?"

"Yes," I said. "Everything takes longer, so we're making less money, and it's still expensive for the rider. So how's the ride?"

"It's great!" he said. "Wonderful!"

"Well there you have it then."

Even from supposedly reputable brands, low end bikes are shockingly shoddy. The upper end is staggeringly expensive not only to purchase but to maintain, if you really use it hard. Even if you want to settle for fewer features but well made componentry, it's a treasure hunt to find parts, and you'll need to know how to do your own work.

Biking has no use for elder statesmen. Expertise is only good for a short time. Does anyone in mountain biking today care what the pioneers of the sport think? Only if those pioneers repeat currently popular opinion. You're only as good as your last ride.

George's rocket

When Big G finished building up his new Specialized Roubaix last week, he put it on the scale in the shop.

Drum roll...

Twenty-two pounds. Carbon fiber and bla de bla,and the friggin' tank weighs twenty-two pounds.

Mind you, 22 pounds is a perfectly respectable weight for a top quality butted steel racing bike from the 1980s. In other words, thanks to tinfoil chains, cog-packed clusters and temperamental, expensive brifters, we have achieved equality with a simpler machine powered by the same engine 30 years ago.

I know: more gears! Convenient shifting! And with the simple investment of at least a thousand more dollars in crank, handlebars, stem and wheels the bike could be an easy two pounds lighter. Still temperamental, but the fancy ones always put you through hell. You have to decide for yourself whether the ride is worth it.

Planning to commute on his new steed, Big G has been checking out all the bag options. Frame packs, enormous, projecting seat packs, anything that doesn't require a rack. He's got a messenger bag on order. That would not be my first choice for a 25-mile open road ride to work. But then this whole acquisition went entirely where I will never go. All this baggage, of course, gets added to the basic curb weight of the bike.

I understand wanting a light bike. Last summer I got a frame pack to increase the cargo capacity of my own road bike. It's a nice break when I know I'm sticking mostly to pavement. But if you only ride a light bike it will eventually feel heavy to you. And when it comes to transportation I really like the secure feeling I get from wider tires, fenders, lights and a good tool kit.

They got George! Those BASTARDS!

Big G sent me an email the other night. He needed to tell me he had ordered himself a Specialized Roubaix road bike.

After all we've been through, dealing with the mysterious creaks, cracks and pops of carbon frames, and all the headaches of brifters and the Chain of the Month Club, Big G signed himself up for all of it. At what point did he cease to mean it when he said, "I'm so glad I don't own one of these?"

With so many more elegant ways to achieve a light bike that would also be simple and durable over the long haul, he chose to buy off the rack and shackle himself to this year's "state of the art." Hell, it's not even this year. It's more like six months at best.

The bike arrived today. The box looked like it had been drop-kicked all the way from Taiwan, but the bike appears unblemished. Unblemished except by the details of its own design, that is. So it's a matter of opinion. Big G won't be in until Friday. The bike will await him, in its exploded box. I got him something with which to toast his assimilation into the cult of the modern:

It's always hard when you find out your compadre has been replaced by an alien pod. The fact that he could do it with no warning shows they implanted the spores in him a long time ago. Oh, buddy, if only I'd known the struggle you didn't even know you were having...

Ah well. Too late! He's gone to the dark side. I can only help him return if he wants to be helped. Meanwhile I get to bust his balls without mercy. Got a problem there big guy? Waaaa ha ha ha ha!

I know I should be more gung-ho about the bike industry's excrescences. They're supposed to be the latest and greatest, and Enhance your Cycling Experience. Thing is, I was enjoying my cycling experiences a ton back in the 1980s, when all I wanted was enough income to buy more time to spend riding the stuff I already owned. I've made a few changes where I saw real improvements, but the rest of it is expensive horseshit. That being said, riding a bike is still great. Find someone who can help you sift through the horseshit. Even if you get stuck with some ultra-modern (temporarily) crap, the activity itself is still worthwhile. We can get you onto better stuff if you decide you want it. Or we can keep feeding you the industry's latest dump. It's all good. It still beats driving.

Job security or death knell?

The Internet brings me word of the proliferation of 11-speed drive trains and hydraulic disc brakes for road bikes among the many technological bounties showering from the broken sewer pipe of the bicycle industry and its chief driver of costs and complications, Shimano.

As if ten-speed chains did not wear out fast enough. While I chuckle on my own behalf as I ride my 8-speed steed (24, actually, with its hideously outmoded triple crank), I also tear my hair as I consider that most of my time is spent helping customers who have no intention of replacing their old bikes keep them going.

It's like working in rehab. The poor riders come in addicted to their conveniently-located shifting. It used to be state-of-the-art. Now it's relegated to the cheap models. The bike industry wants these dupes to buy newer bikes with more speeds. But they can't afford the stronger drugs you're peddling. And they don't need them.

If you get tagged by some irritable idiot in a pickup truck, does it matter whether your bike had 11 cogs or eight in the rear? Does it matter whether you had electronic shifting and hydraulic disc brakes or barcons and old cantilevers? Will the new bikes ride any better over potholed road edges than the old ones did?

Component manufacturers shove their innovations down through the price points because they need a lot of suckers to buy in to finance the few people who really benefit even slightly from the capabilities of the new machinery. I guarantee that racers will race on whatever they can get. THEY don't drive the innovation unless you can tell them one of two things: it's an advantage other competitors won't be able to get or it's what everyone else has, so they need it to start from an equal footing. But if everyone has it, everyone has it. That was true when it was toeclips and downtube shifting on steel framed bikes and it's true now with exotic frame materials and far more expensive and temperamental drive trains. No one has the technological edge for long. Meanwhile, the innovations warp values throughout the industry and cycling in general.

Now we need another shelf facing in the parts department for 11-speed chains. We have to stock 11, 10, 9, and 8-7-6-5, as well as a few models of 1/2"X1/8" and a 3/16" for good measure. The poor schmucks who want a nice bike and get stuck buying an 11-speed swell the ranks of the Chain of the Month Club even if they've never heard of it. And most people haven't.

"Got this great new bike! Of course my genitals still get numb on a long ride, I still breathe hard and huck up a lung on steep climbs and angry motorists still try to kill me, but thank heaven I have that one more cog!"

Riders may love cycling and still not want to shell out for a new bike very three years. Even among racers -- a small percentage of the cycling population -- there are many who may lust for the newer stuff but simply can't afford it. They'll get the best they can and thrash it and themselves to death.

Far more numerous than the real racers are the citizen riders with their myriad motivations, who buy the best bike they can, with every intention of using it for many years. The bike industry betrays them with its constant debatable "improvements."

As far as I can see the bike industry divides the customer base into two broad categories: the exploited and the neglected. At this they're no worse than many other industries, but when will that stop being the basis of acceptability?

Where's the big noise about improving riding conditions on every road in the country? Where's the huge investment in public image and education that would really increase consumer demand? Does the bike industry believe that will take care of itself or do they actually believe it's not worth the investment? They'll just keep throwing ideas at different rider groups and aim for the center of the biggest flocks until there are no more. As a rider I don't feel supported by them. As a professional mechanic I don't feel supported by them. As a small retailer I emphatically don't feel supported by them.
