Technology

AXS
AXS is SRAM’s new bike component integration system that connects the bike’s electronic components and software. The SRAM AXS app allows riders to see battery status, program components, customize controls, get maintenance reminders, and update firmware.

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

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