The Fiend Team Cranks were designed for a real easy installation/removal while maintaining maximum durability and strength. Built with a 2.5 piece design that features a proprietary internal wedge system in each arm making installation and removal easy. The rectangular shaped arms are made from heat-treated chromoly with one piece sprocket bosses allowing the cranks to be run in either RHD or LHD. A hollow chromoly spindle with a single hollow flush mount spindle bolt ensure the cranks stay fixed, while shedding some weight and not sacrificing strength. ###section### Product Specs Crank Type: 2.5 Piece Drive Type: Bolt Drive Spindle Diameter: 22mm Drive Side: Left & Right Compatible Includes BB Bearings: No Weight: 1000g (35.3oz) ###shogun-image-section###
