A 1X chainring replaces the traditional two chainrings on the crankset, with one single chainring. Our 1X chainrings are made in partnership with cSixx and are engineered to be aero and stiff, while offering excellent chain retention and smooth running in the maximum number of gears.

Our 1X chainrings have been in development for two years, while trying to find the perfect manufacturing partner to take this product to market. In partnering with cSixx, we have found a group of passionate engineers and designers, already manufacturing a heavily refined and field-proven product. Our range of 1X chainrings uses our own ideas, alongside the tooth technology and manufacturing techniques of cSixx, to produce what we believe is the most refined and highest performing 1X chainring solution for time trial application.
