    Mach 4 650b

    Has anyone changed a Mach 4 to 27.5 (650b) wheel format? Did you have to change forks? Any other upgrades or changes?

    Thanks!!!

    I don' t think the 650b wheel has enough clearance on the Mach 4 which is too bad because it would probably make a great conversion. Most 26r forks will take a 650b but you may have modify so the crown will not contact the tire under full compression.
