SRAM DualDrive Rear Hub

This is the favorite drivetrain of our Product Design Group. SRAM's DualDrive system combines a silky smooth 3 speed gear hub with an 8 speed or 9 speed derailleur for 24 or 27 gears and a stunning gear range that’s as low as a mountain bike and as high as a road bike. The DualDrive hub is the smoothest riding gear hub on the market and an added bonus is that it can be shifted even at a stop, so those starts from a red light are a lot easier. A simple one-handed shifter controls both the hub and derailleur.
