Had an idea to put some 700c wheels on an old 26inch mtn bike (1991 Rockhopper comp). I've already made it a single speed with a simple conversion kit.
I guess the two issues are brake mounts (would only need front) and how it would ride. That is would the geometry be much different. Brakes are currently canti's which I'm sure wouldn't hit at the right spot but maybe there are some hacks for this.
Could replace the fork if needed. Currently it's a 1" threaded I think.
Worthwhile or stupid?
