SRAM XX1 new group marks a new era in the mountain range. A front chainwheel and an extremely wide stepped pinion rear block will soon be many bikes of cross counrty up
Allmountain decorate. Absolute Black has developed a combination of single chainring and Spider, which can be mounted on each SRAM GXP crank the groups XX1, X0, X9 or X7. The Combi is bolted directly to the crank arm. This saves weight, is very stiff and ensures a clean as individual appearance. A 7075 Txxx aluminum alloy ensures a low wear.
The chainrings have special teeth that prevent the chain may come off. The principle follows that of SRAM XX1 chainrings. In conjunction with an SRAM or Shimano Shadow Type2 + derailleur, which have greatly increased bias of the cage, the chain is reliably held in place without chain guide.
The ovalization of the rear sprocket increases performance by variation in the drive train and optimizing the resistance. When contact with the legs, the natural strengths and weaknesses to be reconciled. To make better use of the stronger muscle groups is achieved, creating a balance in the working path (lower hub) in the weaker muscles.
