    Rim Brakes reported to convert to 650B

    Tektro CR720
    Tektro Onyx
    Paul Motolite BMX
    Avid tri- align
    Cane Creek curve
    FMF BMX V-brake
    These are brakes I have seen as claiming to be compatible with canti studs on a 26"-650B conversion. I have read that you need 12.5 MM of brake pad adjustment. to work.

    If anybody has 650B axle to rim center measurement please post as well as any other rim brakes that might work.

    Thanks for that, I will add FMF to the list, Can you give a measurement if you still have that set up. Axle to rim center and canti stud center to brake pad bolt center.

    approx. measurements

    292/293mm axle to rim center

    canti stud to brake pad bolt 38/39mm (the FMF is adjustable 20mm below this and 25mm over this.

    canti stud to cable bolt 108mm

    The last measurement is important since that tells you if the cable will clear the tire tread. I don't have a bike set up for these anymore but I just tossed a 650b wheel with a Quasi-Moto into a Kelly 26" fork with brake studs and you need 100mm(from canti stud to cable) to clear the tire by about 5mm or so. I'm not sure if all the brakes you list will clear.
