The special thing about the tuning crank: the material. Cannondale achieves a weight of just 513 grams for the complete crank including 30 mm chainring and BB30 bottom bracket, without using carbon fibre. The CNC-milled aluminium crankarms are made from two shells bonded together and weigh just 116 grams per crankarm. The BB30 aluminium shaft also ensures good rigidity. We rode the crank with a Sram-compatible XX1 spider and 30 mm chainring. The only criticism of the lightweight aluminium crank is the Q-factor. Compared to an XX1 or XTR crank, the crank arms are slightly wider. Apart from a few signs of wear on the crank arms, there is also nothing to criticise in terms of durability. The BB30 bearings also continue to rotate very smoothly.
