A single chainring with a wide-range cassette is a wonderfully clean way to tackle so many disciplines. Gravel, TT, tri or crits: just pick the right chainring size and go. 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.
