SRAM Red 11 Speed GXP Chainset - 50/34t X 172.5mm

Product Description

The SRAM RED® Exogram Crankset is completely hollow all the way to the spider. Its hidden bolt pattern makes better use of carbon fiber 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.

Features: Exogram technology uses a large, hollow cross section all the way to the spider, minimizing weight while maximizing stiffness. Our stiffest crank ever Hidden bolt pattern leverages the characteristics of carbon fiber while presenting a sleek appearance Stiffer X-Glide R™ chainrings feature thicker construction, advanced shift timing pins & ramps, which are optimized for shifting with the Yaw™ front derailleur stunning two-tone finish 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 aluminum 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: Arm
