Classified introduces game-changing 2x drivetrain for mountain bikes.

Classified has entered the mountain bike market with its Powershift Boost hub system, which offers a two-speed gear system housed in the rear hub, retaining the range and gearing of a 2x setup without the need for a front derailleur. The system is compatible with 11- and 12-speed mountain bike groupsets and is available with a new 11-40t 12-speed cassette and a bar-mounted remote called the Ringshifter. Classified claims the gear range of 530 per cent is the largest of any drivetrain on the market. The Ringshifter is a wireless shifter mounted to the handlebar that controls the two-speed hub.
