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.

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.
