With its UBB30 axle, it is compatible with BSA (68 & 73), BB86, BBB89, BB92, BB30, and BBRight bikes. The REX uses a refined and lighter version of the Trinity Drilling System (TDS) hollow construction. This allows the crank to resist rotational and bending forces better than a simple hollow tube construction can.
