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…
Carbon-Ti X-Carboring EVO chainrings for Shimano 12-speed
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 5-piece 8.5g 7075 alloy X-Fix Road kit will bolt on either set of chainrings, available in seven anodized colors for 25€.
Carbon-Ti X-Carboring X-AXS chainrings for SRAM Force & Rival
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.
To bolt up the X-AXS rings, Carbon-Ti has a special 9g X-Fix BCD 107 2x bolt kit with longer 7075 alloy bolts to fit these new SRAM cranks, available in sets of 5 for 25€ in seven anodized colors.
Like everything else they sell, all of the X-Carboring chainrings and bolts are entirely made-in-Italy by Carbon-Ti.
