Lightweight by design. Precise by intention.

The X-CarboRing EVO is Carbon-Ti's latest evolution of its signature carbon and aluminium chainrings — combining advanced materials, refined shifting performance and Italian craftsmanship in a component that feels as purposeful as it looks.

Constructed from structural 3K carbon fibre, CNC-machined AL7075-T6 aluminium and Grade 5 titanium, the EVO generation introduces a thicker carbon structure and redesigned titanium shifting elements. The result is increased stiffness, improved chain engagement and faster, more precise shifting under both electronic and mechanical drivetrains.

Every detail serves a purpose. The exposed carbon weave reduces weight without compromising strength, while the titanium shift elements guide the chain smoothly between rings under load.

Not just lighter.

More refined.
