Gravel Drivetrain Components

XCX Race Carbon Gravel cranks are the result of decades of World Cup racing experience put into the lightest production crankset we've ever made. Sub-360g without a chainring, sub-400g with one. Compression-molded carbon fiber arms, 30mm aluminum spindle, APS preload adjuster, and self-extractor. Available in 170, 172.5, and 175mm lengths with a 68mm spindle and 47mm chainline for proper gravel geometry.

Helix 9-45T cassettes bring legendary shift performance to gravel with 500% range, a direct upgrade from SRAM XPLR's 10-44T with 13% more range. The 9T cog gives you a higher gear for descents and paved sections without sacrificing climbing. A two-piece replaceable design means you swap worn cogs instead of the whole cassette. Compatible with SRAM, Shimano, and TRP shifters and derailleurs. Flat-top chain compatible. XD driver required.

UL chainrings are the lightest 1x gravel rings on the market, strategically machined from the SL platform for maximum weight savings with minimal sacrifice in strength. Available from 30T to 42T with -5mm offset for proper chainline.

Threaded and press-fit bottom brackets with sealed bearings built for wet, gritty conditions. Every component is backed by a 5-year warranty.
