The Shimano XTR M9020 Trail 34/24 11 Speed Double Chainset is ideal for riders who need a wider gear range for those lengthy climbs and values the rhythm a 2x crankset can give your daily ride. These cranks have a cold forged Carbon Aluminium construction with 3D hollow structure to increase stiffness. The Hollowglide outer chainring is made with a titanium/aluminium composite hollow 3D structure to maximize stiffness whilst keeping weight at a minimum and titanium teeth are used to keep it stiff, light weight and hard-wearing. Comes with a standard Q-factor of 168mm which allows the cranks to be compatible with M9000 1x, 2x and 3x chainrings. This crankset comes in Silver with crank lengths of 165, 170, 175 or 180mm.
