Brand new 12-speed gearbox in Black. Maximum strength ratio is achieved with steel internal gears. 600% spread exceeds the range of any lighter 1x drive train. The reliability of this gear box is absolutely second to none. This drive train removes the need to pedal while shifting gears. This is incredibly useful when dropping into a burly descent after a grueling climb
Fits the same drivers that are used for SRAM and Shimano rear hubs (with separate purchase)
No More derailleur dangling off of the rear triangle, pushing the chain around waiting to snap right into your spokes.
Unmatched climbing performance, and downhill durability
Black powder coated surface treatment enhances wear resistance
Gear Box Body: ultra light hot formed magnesium
Shifting in ~17% increments uniformly across the shifting range.
