Reliable, extremely lightweight, stiff and with a clean look at the wheel provide the chainrings of Absolut Black the best solution for SRAM BB30 | PF30 crankset with a short axle. Spiderless chainrings enable an optimal setup for single-speed or 1x 9/10/11-speed drives. These chainrings save more than 150 g compared to conventional Spider / chainring combination.
The Combi is bolted directly to the crank arm. A 7075 aluminum alloy ensures a low wear. Special teeth on chainring effectively prevent the disengagement of track links. The principle follows that of SRAM XX1 chainrings. In conjunction with an SRAM or Shimano Shadow Type2 + derailleur, which have greatly increased bias of the cage, the chain is reliably held in place without chain guide.
ATTENTION: only compatible with SRAM / Truvativ BB30 cranks with a short axle. These are recognized by the built 9 mm spacers on the drive side.
