Technology

AXS
AXS is SRAM's new bicycle component integration system that connects the bicycle'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 pivot and the bearing is the heart of DUB technology. It's where stiffness meets durability. Everything has been made simpler by better integrating the relationship between crown, crank, spindle and bottom bracket. This approach to developing a complete system equates to improved powertrain performance.

DUB-PWR
DUB-PWR takes Quarq's reliable and precise power measurement and elegantly houses it within the DUB crank spindle for compatibility with any chainring configuration, measuring power on the left side to calculate total watts. It is light, invisible and easy to reach.
