Italian weight weenie manufacturer Carbon-Ti have expanded their multi-material carbon, titanium & aluminum X-Carboring EVO chainrings with improved stiffness and more sizes to upgrade any modern 11 or 12-speed road drivetrain. Now available to fit new Dura-Ace & Ultegra 12 cranksets, Carbon-Ti also adds new 110BCD rings for riders with other lightweight cranks & power meters, plus new 107BCD X-AXS rings for the latest Force & Rival cranks, too.

On top of that, there are simply more and bigger chainring combos than stock rings for those who just want to go faster…

With the start of 2022, Carbon-Ti expands their X-Carboring EVO chainring offerings with new 4-arm 110BCD versions for the latest Dura-Ace R9200 & Ultegra R8100 cranksets and power meters, plus SRM Origin power meters. The new 12-speed (and 11-speed) compatible EVO generation of rings start with thicker 3K carbon fiber plates for their big/outer chainrings, allowing Carbon-Ti to more intricately CNC-machine the backside for improved stiffness at low weights.

With the more complex machined carbon ramp hooks and re-optimized grade 5 titanium shift pins mounted to the machined 7075-T6 alloy teeth, Carbon-Ti says the EVO rings grab the chain like a ‘harpoon’ for quicker upshifts both with mechanical or electronic derailleurs. Inner chainrings remain unchanged.

Carbon-Ti X-Carboring EVO DA9200 chainrings are available now individually for Shimano 4-bolt 110BCD in 52/36 & 50/34 combinations, 181€ for small rings (28-33g) & 229€ for big rings (97-104g). Even bigger 54/40 combos will be available starting in February 2022.

Carbon-Ti also offers the same X-Carboring EVO rings for standard 5-bolt compact 110BCD cranks and power meters in the same gearing at the same pricing, compatible with Shimano 12sp, Campagnolo 12sp, and all previous 11-speed groupsets.

The new Carbon-Ti X-Carboring X-AXS chainrings in 107BCD are made to upgrade your stock rings on the latest SRAM Force & Rival AXS 12-speed cranksets, all with flattop compatible tooth profiles. These X-AXS chainrings get the same thicker, stiffer EVO tech big rings scaled down to the smaller 107mm 4-arm bolt circle diameter of the latest Force & Rival cranks, and with the requisite smaller chainring combos suited to SRAM’s smaller XD-R cassettes.

Carbon-Ti thinks they make a great replacement for these otherwise affordable groupsets, for a claimed 50g savings over stock Force rings, while giving a fully bling performance upgrade.

Carbon-Ti X-Carboring X-AXS chainrings are available now for SRAM 4-bolt 107BCD in standard Force  46/33 & 48/35 replacement gearing, plus a bigger 50/37 combination that SRAM only offers for their top Red AXS cranks. The X-AXS rings sell individually for 181€ for small rings (30-41g) & 229€ for big rings (83-101g). All available from late January 2022.

This soooooo reminds me of the good ol’ days of “Drillium” (just drill out where there seems to be any extra materials)….buddy of mine did that to his crank arms…some weeks later, his crank drilled out his calf muscle.

Any word on how quickly these wear vs standard aluminum rings?

Interesting that Carbon-Ti is the only company making a Flat Top compatible shift ring so far. Hopefully more companies will follow suit so we can have some more affordable options.

Not just Rotor. Praxis also has flattop compatible chainrings.

Honestly this product has not really a point of existence anymore except show value. It is not lighter anymore then a set rotor alu rings or praxis rings though at more then triple the price. Shift performance is not better then the default and certainly not in case of shimano rings
