Complete 2-speed transmission set. Includes 46T and 49T molded composite spur gears, 2nd gear shoe set, alloy gear holders with integrated bearings, and all hardware.
The 2-speed transmission parts are installed on a precision-manufactured super-smooth lightweight hollow middle layshaft made from tough HUDY shaft steel for 2-speed, which is additionally heat treated for extra strength and long life.
The 2-speed gear adapter is CNC-machined from Swiss 7075 T6 for precision fitment of the 1-way bearing, allowing super-precise and wobble-free running of spur gears. High-quality one-way bearing is hand-ground before installation for maximum running precision and strength. The 2-speed adapter is manufactured from hardened steel.
