The SRAM RED Exogram Crankset is completely hollow all the way to the spider. Its hidden bolt pattern makes better use of carbon fibre to further improve stiffness & shed weight. The stunning X-Glide R chainrings are optimized for use with the Yaw™ Technology in the front derailleur, delivering seamless, flawless performance. Technology Exogram The new Hollow Carbon Construction starts in the crank arm & extends into the cranks’ spider. It maximizes the stiffness to weight ratio.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. Specifications for SRAM RED Crankset 10-speed •ARM
