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. The wide chainline crankset fits in road and MTB bottom bracket standards so frames can fit wider gravel tires.
