SRAM RED - BB386 Standard crank with 53/39 teeth and 130mm bolt circle diameter.
Already a legend in its time, the SRAM RED Exogram Crankset is now available with refreshed graphics to compliment the new SRAM RED eTap componentry.
The SRAM RED Exogram crankset features a completely hollow construction all the way to the spider. Its hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. As always for seamless, flawless performance and Yaw compatibility, pair this crank with X-GlideR chainrings.
Features
Exogram -The new Hollow Carbon Construction starts in the crank arm and extends into the cranks' spider. It maximizes the stiffness to weight ratio.
X-GlideR 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, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance.
Yaw -The front derailleur cage rotates to maintain a consistent angular relationship with the chain. Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct, more precise, and combined with the new Red crankset and chainrings, delivers an unmatched performance advantage in front shifting.
