ABSOLUTE BLACK Chainring Direct Mount BOOST 148 | 1-speed narrow wide for SRAM cranks | black
SRAM's XX1 group ushered in a new era in mountain biking. A chainring at the front and a broadly graded sprocket block at the rear now adorn many bikes from cross country to all-mountain. Absolute Black has developed a combination of single chainring and spider that can be mounted on any SRAM GXP crank from groups XX1, X0, X9 or X7. 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 connection with a SRAM Type2 or Shimano Shadow+ rear derailleur, which have a greatly increased preload of the cage, the chain is reliably held in position even without a chain guide.
Note: compatible with Sram/Truvativ GXP and BB30 cranks . BB30 cranks are only compatible if it is the longer axle model. These can be recognized by the built-in 16 mm spacer on the drive side.
