Bike Go Fast

Weight matters.

Instead of the workhorse, I rode the racehorse today: unladen carbon-fiber road bike instead of steel frame hybrid with its rack and bag. The comparison? Night and day. Think sports car vs. minivan.

My typical pace heading to the office lately has been 12.4 mph on the hybrid. On the road bike today? 14.4 mph. My average heart rate was a tad higher. [The bike made me do it.]


There was a reason for commuting on the road bike, and that reason was The Bike Doctor.

I think it's important to support our local bike shops. Over the years, I have entrusted my bikes to the mechanics at seven different shops, including four in the town where I live. [Two of those are no longer in business.] Even at a single shop, the quality of the work has been uneven—a good mechanic works on the bike during one visit, a not-so-good mechanic handles it the next time.

My last visit to a shop in town went like this: I wheel the road bike into the shop first thing on a Saturday morning; it needs a new chain. Best case: they'll install it while I wait, or at least on the same day. Reality: They tell me it won't be ready till Monday. [Sigh.] “Is it slipping?” they ask. “Sometimes,” I reply. A mechanic mounts it on a stand, spins rapidly through the gears, and announces that I need a new cassette. [$$$] “Let's start with the chain,” I reply dryly.

And that was the last time I will bring my bike to that shop for service.

I did not need a new cassette. I did not wear the chain to the point of damaging the cassette. When I did get the bike back, it was badly tuned and occasionally the chain jammed when I up-shifted the front dérailleur. Was that a deliberate misadjustment to send me back to the shop, thinking I needed that new cassette? Or just bad wrenching?

The Bike Doctor is a local bike shop (in a sense). His shop is a truck (low overhead). He visits various corporate campuses in the Bay Area on a regular schedule; he also makes house calls. You schedule an appointment, he fixes your bike, and you get it back within hours (not days). He is a good mechanic, he's honest, and his prices are fair.

And that is why I pedaled the road bike to the office today. Its dérailleur cables were two years old, and I would prefer not to suffer another snapped-cable incident. “Ah yes, Shimano cables will do that.” He understood.

He was on the phone delivering the bad news to another customer when I picked up my bike. The chain on that bike had worn the teeth on the cassette so severely that he marveled it would work at all. He showed me the effect—on some rings, the teeth were barely nubs.

I hopped on my well-tuned bicycle, shifted with my new cables and returned to my building, a happy customer.
