Carbon-Ti X-CarboRing EVO 55/38 x 110 DA9200 (4-Arm) Chainrings

The Carbon-Ti X-CarboRing EVO 55/38 x 110 DA9200 chainring set combines Italian precision engineering with cutting-edge materials for maximum performance. Crafted from AL7075-T6 aluminium, 3K glossy structural carbon fibre, and Grade 5 titanium, it offers unmatched stiffness-to-weight and responsive power transfer for competitive road cyclists.

Designed for use with Shimano Dura-Ace FC-9200, Ultegra FC-8100, SRM Origin, and Rotor INSpider Power Meter cranksets, these chainrings are compatible with Shimano 12-speed and 11-speed groupsets. The 55 T outer ring must be paired with an inner X-CarboRing 38 T or 40 T (110 BCD) chainring for optimal shifting.

Engineered for precision and aesthetics, Carbon-Ti recommends pairing with the X-Cover DA9200 or X-Fix ROAD bolt kits — both machined from AL7075-T6 alloy and available in a range of anodised finishes. Proudly 100% Made in Italy.
