I just got back my 1995 Trek 730 and I plan to use it both as my main rider and as a project bike. I've always thought the frame is a bit on the small side for 700c tires and since I'm open to replacing any and all parts and definately plan to replace the wheels and tires, why not consider a 650b conversion?

I followed the guidelines on Rivendell Bicycle Works website to get a general idea of whether it would physically work on my bike and it seems like going by their criteria, it would. However, I know nothing about bike mechanics so I may be misinterpreting this.

If a 650b conversion would work and I do it, what differences might I expect in the way the bike rides? More stable? Less stable? I plan to put relatively fat tires on it regardless of what I do. Will fatter 650b's make up for the rougher ride from smaller diameter wheels?

Are there other major (or minor) factors that I'm failing to consider?

I'm just in the planning stage right now with no decisions made so I would be interested in experienced folks' input.

I recently came across this 17" Multitrack (mine is 19") that is converted to 26" wheels and the proportions now look very good!
