CORONA CARBON-TI X-CarboRing EVO 55 x 110 DA9200 4 ARMS

CORONA CARBON-TI X-CarboRing EVO 55 x 110 DA9200 4 ARMS

Chainring made from AL7075-T6 aluminium alloy, structural carbon fibre with glossy 3K finish and Grade 5 titanium pins.

The outer chainring with 55 teeth and a 110 mm Bolt Circle Diameter (BCD) with 4 arms is compatible with Shimano Dura-Ace FC-9200 and Ultegra FC-8100 cranks, SRM Origin, Rotor Power Meter INSpider and Shimano Dura-Ace FC-R9200-P power meter.

Compatible with Shimano Dura-Ace 9200 and Ultegra 8100 groups, and with all previous 11-speed Shimano groups. Not compatible with SRAM AXS 12-speed groups (choose the specific X-AXS chainrings). Installation requires pairing with an inner X-CarboRing 40 x 110 (4 arms) or X-CarboRing 38 x 110 (4 arms).

For installation we recommend using the dedicated shaped X-Cover DA9200 kit for Shimano Dura-Ace 9200 cranks, manufactured in AL7075-T6 alloy. Alternatively the X-Fix ROAD kit is available, custom laser-engraved and offered in a wide range of anodized colours. 100% made in Italy.

X-CarboRing EVO BCD 110 DA9200 (4 arms) are specifically produced for Shimano Dura-Ace and Ultegra 12-speed cranks, as well as for the high-end SRM Origin power meters. The EVO designation identifies these state-of-the-art outer chainrings which incorporate the innovations introduced with the X-AXS chainrings designed for SRAM AXS 12s.

In particular, the outer rings are now machined from thicker carbon fibre plates to achieve significantly higher stiffness and to allow more elaborate CNC machining. These ramps, together with redesigned titanium elements whose function is to “hook” the chain and transfer it from the smaller to the larger ring, enable lightning-fast shifts with both electronic and mechanical derailleurs.

X-CarboRing EVOs are available in sizes 58/46, 56/44, 54/40, 53/39, 52/36 and 50/34, as well as the new 60/46, 55/40, 55/38 and 54/38 combinations. Compatibility is ensured for Shimano 11- and 12-speed groups (and chains) and SRAM 11-speed groups.

For mounting we recommend the shaped X-Cover DA9200 kit for Shimano Dura-Ace 9200 12-speed cranks, made from AL7075-T6 alloy.

Alternatively, the X-Fix ROAD kit is available, laser-engraved and offered in a rich range of anodized colours.

As with all Carbon-ti products, the new X-CarboRing EVO chainrings are 100% made in Italy.
