🪶 Composite Carbon Fibre and Aluminium Construction

The X-CarboRing uses a composite structure made from structural carbon fibre and AL7075-T6 aluminium. The carbon fibre body features CNC machining and incorporates Grade 5 titanium pins.

This construction helps keep the chainring weight low while providing a structure designed for high-performance road use.

⚙️ Individually CNC-Machined Teeth

Each individual tooth made from AL7075-T6 aluminium is CNC-machined separately and features a specific shape designed to optimise the chainring's operation in different conditions.

The individual machining of the teeth contributes to the precision and correct operation of the chainring within the drivetrain.

🔩 Grade 5 Titanium Pins

The chainring incorporates Grade 5 titanium pins, which form part of the structure designed to support correct drivetrain operation and chain movement between the chainrings.

⚙️ Shimano and SRM Compatibility

The Carbon-Ti X-CarboRing 40T is compatible with Shimano Dura-Ace FC-9100 and FC-9000 cranksets, Ultegra FC-8000 and FC-6800 cranksets, as well as SRM Origin.

The chainring is compatible with Shimano 11- and 12-speed groupsets and with SRAM 11-speed groupsets.

🔗 Compatible Carbon-Ti Outer Chainrings

The X-CarboRing 40T is compatible with the X-Carboring EVO 54 x 110 DA9200 (4-arm), X-Carboring EVO 54 x 110 DA9100 (4-arm) and X-Carboring EVO 54 x 110 (4-arm) outer chainrings.

This compatibility makes it possible to create a 54/40 Carbon-Ti double chainring configuration, pairing the X-CarboRing inner chainring with the corresponding X-Carboring EVO outer chainring.
