Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Here's what I did today with my old mtn bike that needed a new drivetrain.

How do you adjust the chain tension?

I like it a lot. I'm surprised at how lightweight it is...and quiet. It turned out way better than I had expected. I'm going to try it out on the trail soon. Should be exciting...just like being a kid again.

I got lucky with the chain tension. The 32x16 works out well enough to keep the chain from falling off.

This website has an interesting form a person can fill out. It charts gear ratios and corresponding chainstay length.

I can't take credit for it, I got the idea from a friend. He's been commuting daily for a few weeks with no problems. I've only ridden mine for 20 min so far, but I think it should hold up fine.

I think if there was a perfectly sized thin washer to go between the outside spacer and the lock-nut, it would be ideal as they have very little surface contact...but I don't see how there can be much lateral force, if any at all.

The PVC inside diameter fits perfectly over the Shimano freehub, slides on with no play at all.

I'm becoming more convinced that SS is the way to go.
