Middleburn cranks were first developed in 1991 and since then the cranks have undergone many improvements. This is the latest mountain bike crank designed for use with external bottom brackets but also with push-fit bottom brackets with different axle lengths. The design is the result of an advanced 3D and stress modelling technique that ensures they are some of the stiffest cranks on the market, yet lightweight. The cranks are hot forged from high quality 7075 T6 aluminium. They are fully CNC machined before being hand polished, anodized and then hand finished.
