The BSD Walla Sprocket is built tough, like a brick outhouse! Hence the all over brick wall graphic. Built from fully 3D CNC machined 7075-T6 alloy with a dual thickness constructi on that's 8mm thick at the edges and tapers to 6mm at the center to help save weight. A 15/16" center hole as standard can fit on all cranks with the supplied 19mm and 22mm top hat washers. ###section### Product Specs TYPE: Bolt On MATERIAL: Alloy WEIGHT: 90.7g (3.2oz) Show more
