Technologies

AXS
AXS™ is SRAM's new electronic integration platform that combines electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, adjust controls, receive maintenance reminders and update firmware.

eTAP
All of the underlying tech in our new SRAM RED® eTap groupset such as wireless shifting, advanced battery power management and mechatronics technologies are all meant to serve one ultimate purpose, to facilitate the most intuitive and consistent shifting available. This shift logic is called eTap. Right lever makes it harder, left lever makes it easier, both levers shift the front derailleur. Simple, unmistakable, and intuitive.

Bleeding Edge
With this new caliper fluid circuitry, the bleed port has been moved to the bottom of the caliper, and all four piston bores can communicate. This way, during bleeding fluid naturally fills the caliper, resulting in an easier, more consistent bleed.

Contact Point Adjustment
Some people like the instantaneous power of a short lever throw. Others prefer the feel of a longer throw. With Contact Point Adjust, you can pick the position you want your fingers to be in when your brakes are engaged. It’s a quick and easy way to customize the feel of your brakes without having to move the pads. It’s also a way to balance both brake levers to feel exactly the same.

Reach Adjust
Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone.

DeepRange™
Racers and their drivers are faster and more efficient than ever before. But the translation of our cars has not kept pace with this change. It has been limited by tradition. With the sole aim of improving the modern riding experience on the road, Sram has completely redesigned the road bike ratio. The new Deep Range technology. Not only does it offer more translation bandwidth, but this bandwidth is also better. It has “depth“: A smoother, more useful gear graduation. Intelligent shift settings, made possible by AXS™, bring the simplicity of a 1-speed drive to 2 speeds. So you always have the right gear and the translation is not in your way. Drive faster, more efficiently and more comfortably with Deep Range technology.

XDR™
The XDR drive actuator is a universal mounting system for cassettes with sprockets of less than 11 teeth. It enables lighter and more versatile drives without the need for new axle standards, hub conversions or even new cassette tools. The XDR interface is 1.85 mm longer than XD and is designed for racing hub applications. XDR drive units are compatible with all XD cassettes when the cassette is installed with a 1.85 mm spacer behind it.

Flattop™
To be able to offer deep range technology, Sram had to develop a narrower chain. The unique joint shape of the Flattop technology not only enabled the this narrower chain, but also resulted in a quieter operation, increased strength and longevity.

PowerLock®
SRAM chain engineers developed PowerLock® as a tool free, sure, and consistent way to connect our chains. While PowerLock® does not require special tools for install, the especially tight tolerances of 10-, 11- and 12-speed drivetrains mandate that each PowerLock® is good for a one-time application only.
