The Red eTap GXP 52-36 Chainset from SRAM is already a legend in its time. The SRAM Red Exogram crankset is now available with refreshed graphics to compliment the SRAM Red eTap components with a Natural Carbon colour scheme. It features hollow construction cranks all the way to the spider and a hidden bolt pattern. The hidden bolt pattern makes better use of the carbon fibre by improving the stiffness and weight. It is 11-Speed Yaw compatible and for the SRAM seamless and flawless performance is recommended to be used with X-GlideR chainrings and SRAM eTap components.
