A complete range of high-performance chainrings for MTB and ROAD... The X-DirectRing and X-Ring represent the core business of Carbon–Ti’s production. The famous X-CarboRing and X-CarboCam with the central body in carbon fibre and the teeth in aluminium stand out for its lightweightness and exclusivity. The X-Ring Ti EVO, Full Titanium, spiderless X-Ring Ti Integral double chainrings, and the mono-chainring X-MonoSync Ti made in Grade 5 Titanium for aeronautical use were created for more heavy off-road use and guarantee rigidity, impact resistance, and life-span greater than any other product made from aluminium alloys.
