Tropical Diseases of Handlebars

The owner of the Bike from Singapore wants to keep the bike.

"So it just needs a handlebar," he said when he finally got a look at it. True, the bar was just one more item on the list already compiled. He's really attached to this bike. It's my job to see that he can be securely attached.

After he left I stress-tested the bars to see how close they were to failure.

One side was more oxidized than the other. I hit the drop portion of that side sharply with a hammer. With each blow the weakened upper area split a little more.



After that I used a leverage bar to apply steadier force, because I didn't have a heavy glove to protect me from cuts if the whole thing crumpled into jagged bits. It actually broke pretty cleanly.

If you live in a tropical maritime environment and you have drop handlebars you might want to consider using clear tape so you can see what's going on under there. But I think there's more to this mystery than just that. Like maybe he forgot to mention the time it sank aboard an overloaded ferry boat or something. Wherever you live, check your bars every so often. It can't hurt.

Blame Singapore

It started with a broken flange on a Bonerager rear hub. An athletic-looking guy who looked to be somewhere in his flurfties -- what do you call the age we're getting to now? We're not middle aged. That sounds so stodgy. But we're not ferocious young athletes anymore, either. In good shape for our age? That sounds like something you say about 95-year-olds who don't need a walker. Anyway, this guy comes in with his late-1990s LeMond road bike with this cracked hub flange. He said he was grunting up a climb.

I told him the wheel was toast. We discussed his options. He selected a built wheel from a reputable supplier rather than engage my talents for a custom build. Because his bike was very rusty that seemed like a good compromise.

He requested an overhaul on the bike while we waited for delivery of the wheel. We discussed the rust.

I've seen some nasty rust on bikes people ride on their trainers. He admitted to some of that, but he and his wife blamed most of it on the time the bike had spent with them in Singapore, with its tropical humidity and surrounding salt water.

He loves how the bike handles. I said I would check the frame for cracks before proceeding. This I did, in due time, when I finally started the repair a few days later. For some reason the frame was intact. For how much longer, I could not say.

I'm so glad I unwrapped the handlebars before I went too far on any other work. I've seen trainer corrosion, I've seen metal fatigue. This was the first time I had seen handlebars that had literally turned to powder inside the bar tape.
POWDER!
I was able to poke a screwdriver through the handlebars in many places. See?

I called a halt to this repair until the customer can see what we're up against. I've suggested he transfer the many good surviving parts and his groovy new rear wheel to a Surly Pacer or similar sporty road frame.

I can't believe he was riding this. He was one good pothole away from collapsing those bars.
