Hollow carbon power.
SRAM's Red groupset has solidified a spot among the frontrunners of the peloton with its precise, reliable, "True 22" shifting. The Red 22 GXP Crankset sits at the center of the group, guiding the chain with SRAM's innovative Exogram technology for exacting power transfer and clean gear shifts.
While the original SRAM Red crankset used a carbon-wrapped foam core to mold the cranks, the current design incorporates a true hollow cross-section. By laying-up the carbon to create a higher volume spider and larger diameter crank arms, SRAM is able to use less material while maintaining the power-transferring stiffness we expect from a carbon crank.
The spider was also rotated to take advantage of the new shape, situating the fifth mounting bolt on the back of the crank arm itself to reduce deflection during shifting and extra-mashy efforts. While the spider arms have been reduced to four, SRAM still uses a 130mm bolt circle diameter on the standard cranksets and 110mm on the compact cranksets for compatibility with aftermarket chainrings.
The included SRAM Exogram chainrings are machined from 5mm thick 7075-T6 aluminum and feature SRAM's X Glide R design to complement the movement of the yaw-caged Red front derailleur. SRAM used extensive computer-aided finite element analysis to optimize stiffness, shift pin locations, and ramp profiles for smooth shifting that still allows the removal of any excess material to save weight.
This particular Red 22 GXP Crankset is compatible with the SRAM/Truvativ GXP bottom bracket standard, including the low-friction hybrid ceramic bearing option.

- Q & A
Would the GXP version of this crank work with a "PF86" frame like the new BMC roadmachine 01? Thx!
Yes, you will just want to use a compatible BB such as Item # SRM0362.
Can this SRM008T red 11 speed be used as an upgrade on a 10 speed SRAM groupset in place of a SRAM Rival crankset on a 2013 Pinarello KOBH
hey Vincent yes you can use that with your 10 speed, hit me up if you have any question on that.
