Designed with a hidden bolt pattern on the spider to get the most out of the carbon fibre construction, this efficient chainset sheds weight with minimal effort for a streamlined & dependable experience. With hollow yet durable crank arms at the ready to push your chain around the X Glide R chainrings, a trusted & powerful rotation is achieved, with the rings themselves optimised specifically for Yaw technology compatible front mechs. An excellent addition to any 11-speed system, the Red 22 Chainset 11 Speed BB30 works hard to get you where you need to be. Technologies: X-Glide R Chainrings: The chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminium CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, & nearly every shifting feature of the chainring. Chainrings, chain, & front derailleur are designed as a single integrated system for optimized performance. EX0gram: The new Hollow Carbon Construction starts in the crank arm & extends into the cranks’ spider. It maximizes the stiffness to weight ratio * Please note, Bottom Bracket is NOT included.
