Already a legend in its time, the SRAM RED crankset is now available with refreshed graphics to complement our new SRAM RED e Tap componentry. The SRAM RED crankset features a completely hollow construction all the way to the spider. Its hidden bolt pattern makes better use of carbon fibre to further improve stiffness & shed weight. As always, for seamless, flawless performance & Yaw compatibility, pair this crank with X-Glide R chainrings. The new Hollow Carbon Construction starts in the crank arm & extends into the cranks’ spider. It maximizes the stiffness to weight ratio. 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.
