  • Radial braking system
    Patent number: 4531754
    Abstract: An improved radial braking system uses the power of the cyclist's back pedaling to bring the braking member into contact with the rim of the wheel. The system allows for the direct contact of the braking member with the middle portion of the outer surface of the rim rather than to the side of the rim, as is common with the caliper type brakes. A rim having a laterally disposed lip for mounting of the spoke allows for an unobstructed middle portion for contact with the braking member.
