Riderx,
Out of idle curiosity, what gear ratio is usually used on single speed bike? While I would imagine that it depends a lot on the rider and the terrain, I'm wondering if you tend to go with a high gear so you don't spin out when going fast, or a lower gear so you have a faster cadence at the lower speeds and on hills? Or do you just take what comes on the bike you get and learn to live with it?
Like Jon, I can see the attraction of a minimalist machine, and I think that I might try experimenting with it simply by not shifting on my next ride and see what I think of it...
