Material

- the production material is extra strong, high quality 100% aluminum 7075 T6
- the rear sprocket is thus much lighter, very strong, resistant to bending and twisting
- the main features are the highest hardness and thus wear resistance
- the rider himself will appreciate the features when riding in extreme conditions

Weight

- all models are designed for maximum performance
- light weight plays a big part in this
- our engineers use a special computer program to develop the rear sprocket
- the result is minimum weight, highest resistance, strength against impacts, bending and twisting

Precision

- even the slightest inaccuracy can spoil a rider's performance
- therefore, we constantly check accuracy and precision during production
- the long-developed gearing has our specific and very efficient shape, which we constantly check
- we achieve the maximum possible quality and service life of the sprocket thanks to our tooth shape
