Sram’s new AXS (pronounced “access”) 12-speed components are a real game-changer, revolutionising the connection between a rider and their gears. This wireless electronic system provides incredibly quiet, secure and smooth shifting, while also offering you the most versatile range of gears to date.
The AXS system allows you to customise how your gears operate, and then gives you incredibly useful feedback on how you’re using them. It also offers you a vast range of different gear setups, suiting everyone from the Time Trialist wanting super-close ratio gears to the Randonneur/Audax rider who needs a wide range to cover all eventualities.
AXS takes SRAM’s proven eTap technologies and elevates them to the next level, providing you with unparalleled wireless electronic shifting that’s faster than ever before. You won’t need to learn the “feel” of your gears to prevent accidental half-shifts and mis-shifts any more, a simple push of a button will make AXS do all the work for you.
At the heart of it all is the AXS app, giving you access to your ride data and allowing you to customise your gear setup. There’s a really clever Sequential Gearing setting that allows you to only ever worry about changing up or down a gear, with the front mech shifting (and rear also changing a gear or two to keep the change in gear small) automatically at the best point, meaning that you don’t need to worry about what combo you’re in at the front and rear. The app also allows you to check battery status, change component behaviour, personalise controls, get maintenance reminders, and update your firmware.
Quarq’s next-generation DZero power meter platform is named for the DØ Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light. With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke, and software advances, DZero represents the state of the art in power meter technology.
