WOLFTOOTH chainring Oval SDM Direct Mount SRAM GXP | BB30 crank
The Direct Mount chainring of Wolftooth is screwed directly onto the crank arms of Sram cranks.
A conversion is very easy to handle. The Spider is fixed with 3 screws on the back.
The result is a light and rigid combination, the optically also very tidy comes incidentally. Special teeth on chainring prevent the chain may come off. The principle follows that of SRAM XX1 chainrings. In conjunction with a Sram Type2, Type2.1 or Shimano Shadow rear 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.
