Description

ABSOLUTE BLACK Chainring Direct Mount oval | narrow wide for SRAM BB30 Short Spindle | SuperBOOST crank | black

Reliable, extremely lightweight, stiff and with a clean look on the bike, the Absolute Black chainrings are the best solution for SRAM BB30 | PF30 cranks with short axle . Spiderless chainrings provide optimum setup for single-speed or 1x 9/10/11 and 1x12 (SRAM Eagle) drives. With its offset of 0 millimeters, the chainring is also suitable for current SRAM SuperBOOST cranks . The chainrings save more than 150 g compared to conventional spider / chainring combination. The station wagon is screwed directly to the crank arm. A 7075 aluminum alloy ensures low wear. Special teeth on the chainring effectively 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.

Ovalization of the chainring enhances performance through powertrain variation and drag optimization. When pedaling with the legs, the natural strengths and weaknesses are reconciled. Thus, a better use of the stronger muscle groups is achieved and in the weaker muscles a balance in the working path (lower stroke) created.

Note: The chainring has no offset and has only been optimized for short shaft BB30 cranks (SRAM XX1, X01, X0, X9, X7, S2210, S1400). These are recognizable by the installed 9 mm spacer on the drive side.
