SRAM Red E1 AXS Power Meter HRD FM Groupset 2x12-speed 37-50

The SRAM Red E1 AXS Power Meter HRD FM groupset for a 2x12-speed road drivetrain with a gradation of 37-50 teeth

With the Red 1 E1 Aero AXS Power Meter HRD FM groupset from SRAM with Red E1 2x12-speed drivetrain, crankset with carbon arms and a gradation of 37-50 teeth, power meter spider and hydraulic disc brakes with flat-mount attachment, you can fully equip your road bike. The drivetrain is controlled wirelessly and ensures precise, fast gear changes, while the hydraulic disc brakes not only look good, but are also powerful. The power meter crank helps you to keep an eye on your performance and train effectively. The shift/brake levers are designed for different hand sizes and shapes and can be adapted to your needs in terms of reach and contact point. You can use the AXS app to customise your drivetrain, view performance data and configure two additional buttons on the sides of the levers.

Technology:

AXS
AXS is SRAM's electronic integration platform that combines electronic bicycle components and software. The SRAM AXS app allows you to view battery status, change component behaviour, adjust controls, receive maintenance reminders and update firmware.

Reach Adjust
The fit and ergonomics of the brake lever is a very personal matter. Riders have individual position preferences as well as unique hand sizes and finger lengths. The grip width adjustment makes it child's play to adjust the lever - for maximum control.

Bleeding Edge
Bleeding Edge technology allows quick and easy bleeding of the brakes. Due to the special fluid channel and the improved bleed opening, the fluid can be pumped more easily through the brake calliper. A special adapter can be fitted to the bleed port and seals the system to prevent air ingress and fluid loss.

Stealth-a-majig
With Stealth-a-majig, installing the hydraulic hose during assembly is child's play. Its smaller size allows easy internal cable routing, which gives the bike a tidy look.

DUB
The unit of crankshaft and bottom bracket is the heart of the DUB technology. Stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It is mainly the system approach through the integration of chainring, crank, spindle and bottom bracket that means better drivetrain performance.

X-Range
The X-Range technology was developed with the possibilities of today's dropbar bikes in mind. It is distinguished by a broad gear range with smooth, even gear changes. The combination of chainrings with 13-tooth spacing with a high bandwidth cassette, starting with a 10-tooth sprocket, ensures well thought-out, homogeneous gear jumps and always puts you in the right gear. In combination with AXS, you can make various shift settings and personalise your drivetrain to suit you.

X-Sync
The X-Sync tooth design is characterised by long, rounded and slanted tooth edges with a narrow profile. Derailleur pulleys with X-Sync technology support the chain guide and remain unaffected by dust and mud.

Orbit
Orbit technology is an innovative form of rear derailleur movement control. It uses silicone fluid as part of an elegant and ultralight damper system. Compared to a conventional friction clutch system, the Orbit technology generates no additional resistance at the rear derailleur spring during slow or light movement. This results in easier shifting and removal of the rear wheel. During the ride, the liquid damper holds the chain back in a sophisticated and elegant way. With the highest reliability and chain tension, for 2x and 1x systems.

Yaw
The Yaw technology allows trim-free shifting, as the front derailleur cage describes an arc and is therefore at a constant angle to the chain. Shifting transitions are thus more direct and precise, providing unprecedented performance when shifting up front.
