Main Drive freewheels have been the "Reliable Replacement" of choice for 25 years. Intended for BMX, fixie, and other single speed bikes, they feature 2 pawls engaging simultaneously every 18°.
MD Freewheels thread onto standard 1.375"-24tpi hub threads (if you currently have a 16T or larger freewheel, it is most likely compatible). Sprocket pitch is 1/2" x 1/8", compatible with 1/8" wide, single speed chains (3/32" wide chain will not fit).
MD Freewheels feature 4-notch removal, compatible with ACS and other brand removal tools. Chrome Plated.
