Quarq D4 1X Chainring

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.

Each purchase includes a chainring and chainring caps (chainring bolts not included). For bundles with a chainring, backing plate, chainring bolts, and caps, scroll at the bottom of the page please.
