I need a project, wanted a touring bike, and picked up a bare metal Trek 520-no paint, decals, parts, fork etc. Factory specs and examples I have looked at indicate that this model was built for 700C wheels. The rear brake bosses on this particular frame, however, are set up for 26" wheels. I can't decide whether I should/could move the original bosses to "spec" position and get a fork to match or leave them where they are and find a 26" fork. The frame is the same size as other examples I know of with the larger wheels. When I drop a 700C wheel into the dropouts, there are adequate clearances at the bridges for fenders-it looks pretty "normal." I wonder if the finished bike will look silly with monster spaces under the fenders and around the wheels.
I started this project as an educational exercise so moving the bosses etc would fall under "tuition cost." Interesting introduction!
Thanks for your insight.
