Even gear combinations
Appologies if this has been done before. I read that even gear combinations, such as 48/18, which my bike shop wants to use, are harder on the "drive train." I can't imagine why. I guess that's not a great combination for skidding, but I don't see that as a real concern for me right now. Is it really a problem to go with even gear combinations?

That gear ratio also offers lots of skid patches.

Is there an even gear ratio that doesn't offer a pathetically low number of skid patches? I would figure this out for myself but I'm quite lazy.

Yep, looks like you can't do better than 10 skid patches with an even-even pairing. I suppose that's not pathetically low though.

skid patches are like boyscout merit badges for fixed gear riders. some gear ratios look funny and give you less cool points or "skid patches", were skidding is like, the ultimate cool of fixies.

The more skid patches there are, theoretically the longer the tire will last because it will wear in many different places on the tire.
