FIXED GEAR ARCHIVE

Profile Spline Drive Spider

Description:

When mounted to a fixed gear bike, a standard BMX crankset has a major problem- the forward and backward pressure on a conventional BMX crank’s sprocket bolt saws at the the bolt and loosens it, which tends to damage the sprocket quickly. The spline drive system is an ideal way to solve that, since it places all of the force that had been on one bolt, and transfers it to the 48 splines of the bottom bracket spindle- the same 48 splines that hold the cranks in place.
