Carbon-Ti X-SingleCarbon Road Chainring 110x4 X-SRM

The Carbon-Ti X-SingleCarbon Road Chainring 110x4 X-SRM is a single-ring road chainring for riders running a 1x drivetrain, made for SRM power meter spiders with a 110mm, four-arm bolt pattern. It combines a carbon fiber outer plate with a CNC-machined aluminum tooth ring, a hybrid build that keeps weight down while giving the teeth a durable surface that stands up to repeated shifting and hard efforts.

Carbon-Ti, an Italian company, has focused on lightweight titanium and carbon components for years, and the X-SingleCarbon is its take on a dedicated 1x road ring. The narrow-wide tooth profile is designed to hold the chain in place without a front derailleur, which suits time trial and triathlon setups, where simple, quiet drivetrains are common, and riders who want to drop the front mech on a road bike.

It is available here in 48, 50, 52, 54, and 56 teeth. Those are large rings meant for flat, fast riding rather than steep climbing, so choose your size against your cassette range and the terrain you ride. This item is built to order, so plan on a longer lead time than an in-stock ring.
