SRAM Red E1 AXS HRD FM groupset 2x12-speed 35-48

The SRAM Red E1 AXS HRD FM complete groupset for a 2x12-speed road drivetrain with a 35-48-tooth range

The SRAM Red 1 E1 Aero AXS HRD FM complete groupset, with Red E1 2x12-speed drivetrain, 35-48-tooth crankset, carbon crank arms, and hydraulic disc brakes with flat-mount fitting, is the ideal complete build for your road bike. The drivetrain is controlled wirelessly for precise, fast shifts, while the hydraulic disc brakes not only look great but also deliver powerful stopping performance. The shift/brake levers are designed for different hand sizes and shapes and can be adjusted for reach and contact point to suit your needs. Using the AXS app, you can personalize your drivetrain and configure two extra 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 a brake lever are a highly personal matter. Riders have individual position preferences as well as unique hand sizes and finger lengths. Reach adjustment lets you fine-tune the lever with ease, for maximum control.

Bleeding Edge

Bleeding Edge technology enables quick and easy brake bleeding. Thanks to a dedicated fluid channel and a redesigned bleed port, fluid pumps through the caliper more easily. A special adapter fits onto the bleed port and seals the system to prevent air ingress and fluid loss.

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 look.

DUB

The crank spindle and bottom bracket unit is at the heart of DUB technology. Here, stiffness meets durability. SRAM has gone a step further, making everything simpler and better. It's largely the system 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 with a wide gear range combined with even, smooth shifting. Pairing chainrings spaced 13 teeth apart with a wide-range cassette starting at a 10-tooth cog delivers well thought-out, consistent gear steps and always puts you in the right gear. Combined with AXS, you can make various shifting adjustments and personalize your drivetrain to suit you.

X-Sync

The X-Sync tooth profile features long, rounded, angled tooth edges with a narrow profile. Derailleur pulleys with X-Sync technology support chain guidance and stay unfazed by dust and mud.

Orbit

Orbit technology is an innovative form of rear derailleur cage motion control. It uses silicone fluid as part of an elegant, ultra-light damping system. Compared to a conventional friction clutch sys
