Carbon-Ti

Carbon-Ti built its reputation on a single idea: a carbon fiber internal structure bonded to titanium alloy teeth makes for a chainring that’s lighter than aluminum and more durable than pure carbon. The Italian brand has been executing that concept since 2005 — expanding from chainrings into disc rotors, derailleur hangers, and drivetrain hardware — with results tested at the UCI World Tour and XCO World Cup. Every component is 100% Made in Italy, manufactured at their facility in Cazzago San Martino, Brescia.

At RA Cycles, the Carbon-Ti collection spans chainrings for Shimano and SRAM AXS drivetrains in 4-arm and 5-arm configurations, X-Rotor disc rotors in multiple sizes and mounting standards, UDH-compatible derailleur hangers in six colorways, and the supporting hardware that rounds out a high-performance drivetrain.

About Carbon-Ti

Carbon-Ti traces its roots to LLS Titanium, a Brescia-based manufacturer specializing in special alloys and carbon fiber. The first Carbon-Ti chainrings launched in 2005, combining a carbon fiber internal structure with titanium alloy teeth — lighter than aluminum, more durable than pure carbon. Carbon-Ti srl became an independent company on January 1, 2020, while keeping production and headquarters in Cazzago San Martino, Brescia. The brand’s components have been raced at the UCI World Tour, XCO World Cup, international marathon races, and the Cape Epic, and are now distributed across more than 20 countries.

The RA Cycles Carbon-Ti collection centers on the brand’s chainring lineup — the X-CarbonRing and X-CarbonRing EVO families cover 4-arm and 5-arm configurations for Shimano Dura-Ace 9200/9100 and SRAM AXS, while the X-SingleCarbon and X-AeroRing add road-specific options. The collection also includes X-Rotor disc rotors in 140mm, 160mm, and 180mm sizes with X-AFS and Centerlock mounting, UDH-compatible X-Hanger derailleur hangers in six anodized colorways, and a freehub body conversion kit.
