SRAM Crankset Force 1x D2 DUB - Unicorn Grey w/Laser Foil - 172.5mm Direct Mount 40T (BB not included)A single chainring with a wide-range cassette is a wonderfully clean way to tackle so many disciplines, and we’re the 1x leaders.

Our lightweight and strong direct mount chainrings feature X-SYNC tooth technology to maximize chain retention, and they bolt to carbon arms with a spectacular but subtle finish.
