Carbon-Ti X-CarboRing EVO 54/38 x 110 (4-Arms) Chainrings
Lightweight Carbon Construction. Precision Shifting.
 
The Carbon-Ti X-CarboRing EVO 54/38 Chainring Set combines advanced carbon fibre construction with precision-machined aluminium chainrings to deliver a lightweight, high-performance upgrade for compatible Shimano road cranksets.
Featuring a 54-tooth outer chainring and 38-tooth inner chainring, this combination is designed for riders who prefer larger road gearing for racing, fast group rides and high-speed riding.
The X-CarboRing EVO uses a carbon fibre structural carrier combined with CNC-machined aluminium teeth, reducing weight while maintaining the stiffness required for efficient power transfer and precise front shifting.

Carbon Fibre Meets CNC Aluminium
The X-CarboRing EVO construction combines the structural advantages of carbon fibre with the durability and shifting performance of aluminium chainring teeth.
The carbon structure helps reduce unnecessary weight while providing a rigid platform for the chainrings, while carefully engineered shifting profiles support smooth transitions between the 54T and 38T rings.
The result is a premium chainring upgrade that combines performance, technical engineering and Carbon-Ti's distinctive aesthetic.
54/38T Performance Road Gearing
The 54/38T combination provides a larger outer chainring for riders who regularly maintain higher speeds, while retaining a 38T inner ring for climbing and varied terrain.
With a 16-tooth difference between the chainrings, the combination offers a familiar gearing step for riders accustomed to modern Shimano road double cranksets.

Important Compatibility Information
Carbon-Ti offers several 110 mm, 4-arm chainring interfaces, so crankset compatibility must be checked carefully.
 
For the standard 110 mm 4-arm version, Carbon-Ti specifies SRM Origin and Rotor INSpider cranksets. Shimano Dura-Ace and Ultegra cranksets require their corresponding DA9200 or DA9100 versions.
 
The 38T inner ring is compatible with selected 54T EVO outer rings, but the correct pairing and mounting hardware must be confirmed.
