The confidence inspiring Gravity Light crankset has been revised to be now stiffer and lighter than ever. For added strength it is equipped with hollow forged AL7050 crank arms and ChroMoly steel pedal thread inserts. The outer chainring is made of 7075 T6 aluminium, the inner chainring and the chainring bolts consist of heat-treated CroMoly steel. The delivery includes a BB30 bottom bracket and a polycarbonate bash guard that protects against rocks an logs. Q-Factor: 167 mm, chainline: 46.5 mm.
BB30 bottom bracket technology is lighter, narrower, stiffer and more durable than traditional bottom bracket systems. Oversized alloy spindles and bearings pressed directly into the bottom bracket shell offer weight savings up to 12%. In combination with a crankset for the BB30 bottom bracket new standards for stiffness to weight ratio will be reached. Advantages of the system are: lighter, stiffer, low Q-factor (narrower cranks, increasing ankle clearance), more durable because of significantly larger bearings and the use of ceramic bearings results in longer bearing life. Compatible with Shimano and SRAM 10-speed shifting systems.
