Middleburn cranks were first developed in 1991 and since then have undergone many refinements. This latest 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 cranks are hot forged from high quality 7075 T6 aluminium. They then go through a CNC machining process before being hand polished. After being anodised they are re-machined with the Middleburn logo! All cranks go through the same procedure so whichever crank arm you choose it will be of the highest quality.
Middleburn RS8 cranks come complete with axle, axle nuts and fittings and are for use with external bottom brackets. They run a 24mm axle that is compatible with the Shimano hollow tech 2 system.
Weight: Approximately 547g for the RS-X-175 including all fittings.
Q factor equals approximately 182mm.
Available in lengths of 165, 170 & 175mm.
