Middleburn RS8 X-Type Crank 175mm Black
Middleburn's external BB crank - the X-Type. It uses a floating 24mm alloy BB axle with Middleburn's own spline on each end. It requires a standard external bearing BB like a KCNC Shimano Fit, Hope or Chris King - not supplied! The LHS arm has an adjuster to take up axle float and lightly load the bearings. This crank comes without a spider or rings.
