Shimano SG-3C41 Nexus 3sp Coastr Hub36h

If your bike has horizontal dropouts (the ability to change the wheel position to adjust chain tension) then you can build this hub into a wheel enabling your bike to have the simplicity of a 3-speed internal gear system complete with a back-pedal brake.

120mm Over-Locknut-Dimension (for frames with 120mm between the rear dropouts).

 Shipping Weight: 1.8kg.

Kit includes hub with nuts and axle stability washer, 21-tooth sprocket, brake arm clip, twist-style 3-speed shifter and cable.

Internal Gear Shifting - Gear shifting action is independent of pedalling. You can shift gears any time, while standing still, pedalling or coasting.

Heavy Duty Construction - Rugged planetary and step-up gear sets assure long trouble-free service.

Integral Coaster Brake - Back pedal braking action eliminates the need for a brake cable to the rear wheel.

Shift Modulator Mechanism - Smoothes out the shifting action while pedalling.
