Middleburn RS7 cranks are compatible with square taper type bottom brackets with the JIS axles. The RS7-SQ-175 crankset weight is approximately 434g including the lock ring. The cranks are available in the lengths of 160mm, 165mm, 170mm, 175mm and 180mm in a choice of either a silver or black finish.
Middleburn cranks were first developed in 1991 and since then the cranks have undergone many refinements. The RS7’s were really introduced as MTB tyres were getting wider and the need for crank arms to clear the wider chainstays on frames.
The cranks are hot forged from high quality 7075 T6 aluminium. They are fully CNC machined before being hand polished, anodised and then finished off by hand. All the cranks go through the same procedure so whichever crank arm you choose will be to the best quality.
The cranks do not come with the Self-Extracting Bolts as shown in one of the pictures but they can be purchased separately
