Middleburn RS7-X type cranks have the tried and tested profile as the classic RS7 square taper cranks but comes with a 24mm hollow axle for use with HT2 style external bottom brackets

The cranks are hot forged from 7075 T6 aluminium then CNC machined before being hand polished, anodised and re-machined with the Middleburn logo. The design is the result of advanced 3D and stress modelling techniques that ensures they are amongst the stiffest cranks on the market but also lightweight.

The weight of the 175mm RS7-X-175 cranks is 547g including all fittings. Q factor is approximately 190mm.

Includes spacers for use with 68mm or 73mm bottom bracket shells
