Technology

AXS
AXS is the new bicycle component integration system from SRAM that connects electronic bicycle components and software. The SRAM AXS app allows cyclists to view battery status, programme components, customise controls, receive maintenance reminders and update firmware.

DUB
The relationship between the bottom bracket spindle and the bearing is at the heart of DUB technology. It is where stiffness meets durability. Everything has been made simpler by better integrating the relationship between chainring, crank arm, spindle and bottom bracket. This approach to developing a complete system delivers better drivetrain performance.

DUB-PWR
DUB-PWR takes Quarq's reliable, accurate power measurement and houses it elegantly inside the DUB crank spindle for compatibility with any gearing configuration, measuring left-side power to calculate total watts. It is lightweight, invisible and easy to access.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
