ABSOLUTE BLACK chainring direct mount BOOST 148 | 1-speed narrow wide for SRAM crank | black
SRAM's XX1 group ushered in a new era in mountain biking. A front chainring and a wide stepped pinion block decorate many bikes from Cross Counrty to Allmountain. Absolute Black has developed a combination of single chainring and Spider that can be mounted on any SRAM GXP crank in the XX1, X0, X9 or X7 range. The combination is screwed directly to the crank arm. This saves weight, is very stiff and ensures a clean and individual look. A 7075 Txxx aluminum alloy ensures low wear. The chainrings have special teeth that prevent the chain from jumping off. The principle follows that of the SRAM XX1 chainrings. In conjunction with a SRAM Type2 or Shimano Shadow + rear derailleur, which have a greatly increased bias of the cage, the chain is reliably held in position even without chain guide.
Note: compatible with Sram / Truvativ GXP and BB30 cranks . BB30 cranks are only compatible if it is the longer axle model. These are recognizable by the installed 16 mm spacer on the drive side.
