Carbon-Ti X-CarboRing EVO BCD 110 mm (4 Arms) DA9200 Ultralight Aluminum/Carbon Chainring

Carbon-Ti X-CarboRing / X-CarboRing EVO BCD 110 (4 arms) DA9200 are the latest evolution of super light chainrings for Road Racing, Gravel or Cross bikes with a composite structure in aluminum alloy and carbon fiber. They are the result of a long process that aimed to create a product very different from those currently available on the market. These are chainrings for double setup, with 110 mm BCD 4-arms, compatible with cranks like Shimano Dura-Ace FC-9200, Shimano Ultegra FC-8100, SRM Origin, Rotor INSpider, etc. produced in 34T-36T-38T-40T-44T-46T (inner chainring) and in 50T-52T-54T-55T-56T-58T-60T (EVO outer chainring).

X-CarboRing / X-CarboRing EVO BCD 110 4 arms DA9200 chainrings are made by coupling a functional part in aluminum (where the teeth of the chainring are) to a structural part in carbon fiber using specific grade 5 titanium pins.

The aluminum part is machined from solid through sophisticated numerical control machining starting from a plate of aeronautical alloy (7075T6). This very hard material guarantees a much longer duration over time than a normal aluminum chainring and helps to limit the premature wear of the chainring itself.

The carbon fiber part has a double function, it acts as a structural support helping to increase the rigidity and to contain the weight at the same time; it also contains specific ramps and slides that facilitate the ascent and descent of the chain during derailing (on outer chainrings). It starts from a high quality carbon fiber plate with a thickness of 5 mm which is initially cut with waterjet technology and then milled with CNC numerical control. Carbon-Ti has invested a lot of time in studying and experimenting with solutions and design capable of guaranteeing the best shifting quality both in terms of precision and speed!

The aluminum part has a black anodized finish, while the carbon fiber part has a glossy 3k twill aesthetic finish.

Special millings are present both on the external and internal side of the chainring, the shape and profile of the teeth with their inclination and exit angle has been designed with a great care by Carbon-Ti, the X-CarboRing / X-CarboRing EVO BCD 110 4 arms DA9200 chainrings has left nothing to chance.

The profile of the teeth is in fact beveled in such a way as to facilitate use with the outermost cogs or the first and last of the drivetrain cassette which are notoriously the most critical but often also the most used. The refined and optimized design allows a very low friction of use and consequent silence with optimal operation even in the most severe conditions.

The fixing standard is BCD 110 mm with 4 arms, therefore dedicated to cranks with this compact standard such as Shimano Dura-Ace FC-9200, Shimano Ultegra FC-8100, SRM Origin, Rotor INSpider. The X-CarboRing / X-CarboRing EVO BCD 110 4 arms DA9200 chainrings are compatible with Shimano Dura-Ace 9200 and Ultegra 8100 groupsets and all other previous 11 speed groupsets (they're not compatible with Sram AXS 12v groupsets : Red, Force, Rival eTap for which are available specific X-AXS chainrings).

It is specified when writing compatible with groups of a certain type, it does not mean that the chainrings mount on the original cranks of that group, but that they are compatible with the rest of the transmission (chain, cassette etc.), compatibility with the crank arm is therefore different from the compatibility with the group. If you have any doubts, please do not hesitate to contact us.

The X-CarboRing / X-CarboRing EVO BCD 110 4 arms DA9200 are chainrings for use on a double chainrings transmission, for the best performance must be used only in these in combinations :

- 34T/50T

- 36T/52T

- 38T/55T

- 40T/54T

- 40T/55T

- 44T/56T

- 46T/58T

- 46T/60T

To be fixed to compatible cranks, the X-CarboRing / X-CarboRing EVO BCD 110 4 arms DA9200 chainrings require male and female chainring bolts of standard length like Carbon-Ti X-Fix Road chainring bolts kit (made of 7075T6 CNC aluminum and available in various anodized colors) but we recommend using the specific X-Cover DA9200 Black kit (compatible with Dura-Ace 9200 12s, Dura-Ace 9200-P 12, Ultegra FC-R8100, Ultegra FC-R8100-P cranks) characterized by standard male chainring bolts and custom female chainring bolts that connect perfectly with the shapes of the crank arms previously indicated. You can always find both types of chainring bolts kit in our webshop.

With weights starting from 28 grams (34T), thanks to the construction technology, the precious materials used and the design with attention to the smallest details, the X-CarboRing / X-CarboRing EVO BCD 110 4 arms DA9200 chainrings are decidedly lighter and aesthetically much more appealing than most of the chainrings on the market. with a racing and elegant look at the same time able to give a touch of exclusivity to your bicycle. 

The high standards of quality, technological level and performance combined with great reliability have allowed the Carbon-Ti X-CarboRing / X-CarboRing EVO BCD 110 4 arms DA9200 to become the official technical partner of the Pro Team UAE Team Emirates. Tadej Pogacar and his teammates have used and still use not only the X-CarboRing / X-CarboRing EVO chainrings but also other Carbon-Ti products (including Carbon-Ti X-Rotor SteelCarbon3 Center Lock dic brake rotors) putting them to the test in the most important international competitions: Tour de France, Giro d'Italia, Vuelta, World Championships, World Tour Classics.

The original packaging, in addition to the chainring, also includes the instruction manual in two languages ​​(Italian and English) all in an elegant protective rigid cardboard box.
