Middleburn - RS7 - Square Taper Crank

Middleburn RS7 cranks are compatible with square taper type bottom brackets. The RS7-SQ-175 crankset weight is approximately 434g including the lock ring. Middleburn RS7 cranks are available in the lengths of 160, 165, 170, 175 and 180mm in a choice of either a silver or black finish. All Middleburn cranks are machined with a JIS taper.

Middleburn cranks were first developed in 1991 and since then the cranks have undergone many refinements.

The cranks are hot forged from high quality 7075 T6 aluminium. They then go through a CNC machined process and are then hand polished followed by anodised before being re-machined with the Middleburn logo. All cranks go through the same procedure so whichever crank arm you choose will be to the best quality.
