About SRAM RED 53-39 172.5mm 11 SPEED Crankset

Already a legend in its time, the SRAM RED crankset is available with graphics to complement our SRAM RED eTap componentry. The SRAM RED 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.

Features

• Exogram™ technology uses a large, hollow cross section all the way to the spider, minimizing weight while maximizing stiffness.
• Hidden bolt pattern leverages the characteristics of carbon fiber while presenting a sleek appearance
• X-GlideR™ chainrings feature thicker construction and advanced shift timing pins and ramps, which are optimized for shifting with the Yaw™ front derailleur
• SRAM Road 11-speed compatible
• Compatible with SRAM RED eTap components
• 110 and 130 BCD

Technology

BB30

Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability, and stronger crank construction.

Exogram

Our Hollow Carbon Construction starts in the crank arm and extends into the crank’s spider, maximizing the stiffness to weight ratio.

GXP®

GXP’s gutter seal design cuts friction, durability and weight—improving both feel and performance.

PressFit 30

It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life.

X-GlideR Chainrings

X-GlideR 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. The chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance.

PressFit GXP

A variant of the external GXP® bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. It requires no change to the crank spindle length and diameter.
