Sram's new XX1 group initiates 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 a Sram or Shimano Shadow Type2 + derailleur, which have greatly increased bias of the cage, the chain is reliably held in place without chain guide.
WARNING: compatible with Sram / Truvativ GXP and BB30 crankset. BB30 cranks are compatible only if it is the model with a longer shaft. These are recognized by the installed 16 mm spacer on the drive side.
