SRAM Red E1 AXS Powermeter HRD FM groupset 2x12-speed 37-50

The SRAM Red E1 AXS Powermeter HRD FM complete groupset for a 2x12-speed road drivetrain with a 37-50 tooth range

SRAM's Red 1 E1 Aero AXS Powermeter HRD FM complete groupset, featuring the Red E1 2x12-speed drivetrain, a crankset with carbon arms and a 37-50 tooth range, a Powermeter spider and hydraulic disc brakes with flat-mount fitting, is the ideal complete setup for your road bike. The drivetrain is wirelessly controlled for precise, fast shifting, while the hydraulic disc brakes not only look great but also deliver powerful stopping performance. The Powermeter crank helps you keep track of your performance and structure your training effectively. The shift/brake levers are designed for different hand sizes and shapes, with reach and contact point adjustable to suit your needs. Using the AXS app, you can personalize your drivetrain, read out performance data, and configure two additional buttons on the sides of the levers.

AXS is SRAM's electronic integration platform, connecting electronic bike components and software.

Reach Adjust

The fit and ergonomics of the brake lever are a very personal matter. Riders have individual position preferences as well as unique hand sizes and finger lengths. With Reach Adjust, the lever can be adjusted with ease - for maximum control.

Bleeding Edge

Bleeding Edge technology allows for fast and easy brake bleeding. Thanks to a dedicated fluid channel and a redesigned bleed port, fluid can be pumped through the caliper more easily. A special adapter fits onto the bleed port and seals the system, preventing air from entering and fluid from escaping.

Stealth-a-majig

With Stealth-a-majig, routing the hydraulic hose during installation becomes child's play. Its smaller size allows for easy internal cable routing, giving the bike a clean, tidy look.

DUB

The unit combining crank spindle and bottom bracket is the heart of DUB technology. This is where stiffness meets durability. SRAM has taken things a step further, making everything simpler and better still. It's largely the system-level approach - integrating chainring, crank, spindle and bottom bracket - that delivers better drivetrain performance.

X-Range

X-Range technology was developed with the capabilities of today's drop-bar bikes in mind. It stands out through a wide gear range combined with smooth, even shifting. Pairing chainrings spaced 13 teeth apart with a wide-range cassette starting from a 10-tooth cog delivers well thought-out, consistent gear steps and always puts you in the right gear. Combined with AXS, you can set different shifting configurations and personalize your drivetrain to suit you.

X-Sync

X-Sync tooth design is characterized by long, rounded, tapered tooth profiles with a narrow width. Pulley wheels featuring X-Sync technology improve chain retention and remain unfazed by dust and mud.
