Clean Rear Disc Freewheel Hub 120 mm
This is the new revolutionary Clean rear hub with integrated freewheel and an incredible 270 clicks (with a 20" standard gear ratio of 18:12)!
The rear freewheel has the major advantages of:
-Increased number of clicks (more direct engagement)
-Minimized rolling resistance (the cranks no longer have a tendency to move forward!)
-(Depending on setup) reduced weight
To use this hub, you will need a rigid sprocket/chainring in the front.
The hub is designed for use with 12mm thru-axles and a width of 120mm (Clean K1/X3 frame).
The hub features a freewheel with 9 pawls in three groups on 60 teeth, resulting in 180 clicks per revolution of the rear wheel. With a standard gear ratio of 18:12 on 20" bikes, you will achieve a total of 270 clicks!
(The usual professional freewheel has 135 clicks. Your pedal stroke will be incredibly direct!)
The Clean freewheel hub achieves this fantastic number of clicks through externally positioned pawls. (Conventional freewheels have the pawls positioned internally. Therefore, with the same outer diameter, more pawls can fit = more engagement points, brilliant!!!)
The hub has 4 sealed, maintenance-free, interchangeable bearings (two inner and two outer), as well as a 6mm spacer on each side.
The left-side spacer can be replaced with the Clean X3 disc brake protector if desired.
For an optimal balance between weight and durability, the hub body is made of high-quality aircraft-grade aluminum and is intricately milled.
The sprocket is integrated into the gear body and is made of the finest SCM440 steel for maximum durability.
The hub comes complete with sprocket, spacers, and 12mm thru-axle.
