Every watt deserves a precise path forward.
 
The X-CarboRing EVO represents Carbon-Ti's latest evolution in lightweight drivetrain performance — combining structural carbon fibre, CNC-machined aluminium and Grade 5 titanium into one of the most distinctive chainrings available today.
Designed specifically for Shimano's latest 4-arm cranksets, the EVO generation introduces a thicker carbon fibre structure and redesigned titanium shifting elements. The result is increased stiffness, improved power transfer and faster, more precise front shifting under load.
 
Constructed from structural 3K carbon fibre, AL7075-T6 aluminium and Grade 5 titanium, the X-CarboRing EVO achieves an exceptional balance of low weight, rigidity and durability while retaining the unmistakable Carbon-Ti aesthetic.
Every detail has a purpose.
Every gram has a reason.
