I'm looking to build a bike up from a frame. I want to do a Gates belt drive with a Rohloff. I'm having trouble finding a good frame for the project. I really like the Budnitz style but way too expensive for me. My guess is a frame only from them would also be too spendy even if they sold frames seperately.
What others are out there? Or should I buy a used and modify?
The closest I can find is a Surly with the interchangeable dropouts. You still need to cut the frame but the dropout bolted on joins the stays.
