[MENTION=424205]Salamandrine[/MENTION] For whatever reason I often find myself wanting to build a bike around a set of brakes. The B. Carre idea happened because I got a set of NOS self-energizing Pedersen cantis that I really want to try, and a good condition set of CLB Super Professional brake levers to pair with them. So I was thinking 70s, French, 650b, canti studs. Obviously not easy-to-find or cheap criteria. So when I saw the damaged Carre frame a lightbulb went on.
