DMR Crisis MTB Cranks arms have been designed to be the perfect match for the new breed of heavy duty BB's which are tough enough to withstand any abuse.
These crank arms are easy to fit and an economical way to get Cro Mo cranks onto your bike. The tough and incredibly stiff 4130 Cro Mo crank arms directly replace standard alloy crank arms and give a stiff, solid feel to the transmission.
