In certain disciplines, the single-chainring drivetrain reigns supreme.
Championing simplicity, strength, and durability, the SRAM RED
1 AXS™ Aero upgrade powermeter meets the demands of triathletes and time
The powermeter is integrated in the direct mount chainring and the tighter gearing range is perfect for racing and areas with flatter terrain. The SRAM RED 1 AXS Aero powermeter is also designed with Quarq DZero™ power measurement into crankset. Thanks to a professional performance-controlled training, you are ready to climb the cycling monuments.
The SRAM RED carbon crankset features a completely hollow crankarm construction called Exogram. It is paired with a particularly aerodynamic direct mount chainring with disc design and X-Sync for perfect chain retention. Like the current SRAM MTB cranks, the SRAM RED crank is also equipped with the universal DUB (Durable Unified Bottom Bracket) crank spindle which can be universally used in all common bottom bracket shells, also increases rigidity. The bearing play will be fine tuned with an adjuster ring.
- 1-speed chainring setup simplifies functionality and reduces weight
- 48 and 50t variants feature direct mount aero chainrings
for better aerodynamics
- the Powermeter is fully integrated into the chainring design and therefore it just adds 36g
- power readings are accurate within +/-1.5% and aren’t affected
by climate conditions during a ride
- Power Balance measures left and right legs separately
- improved front shifting performance for crisp and accurate front shifts
- unique Direct Mount chainring design (not SRAM MTB DM compatible) results in a lighter weight, stiffer, more durable crankset
- DUB™ bottom bracket adds durability, simplicity and broad compatibility
AXS™ is SRAM’s new wireless bike component integration system
that connects electronic bicycle components and software.
The SRAM AXS™ App allows riders to see battery status, change component behavior personalize controls, get maintenance reminders, and update firmware.
