SRAM Rival AXS E1 Front Derailleur

Experience elevated front shifting. The Rival AXS front derailleur uses Yaw cage movement and auto trim for silent, rasp-free running, and a narrower cage shape that integrates with SRAM's X-Range chainring design for fast, clean shifts. SRAM's setup tool means you'll get the ideal position without any fuss, too.

Technology

Yaw

With a front derailleur cage that rotates to maintain a consistent angular relationship with the chain, Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct and precise, delivering an unmatched performance advantage in front shifting.

AXS

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

X-Range

Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings enabled by AXS. With X-Range, you’re always in the right gear.

X-Range achieves wider range and tighter jumps by going to a 12-Speed cassette, but also by moving some of the gear range from the front of the drivetrain to the back. We’ve employed smaller chainrings with a consistent 13T difference, while giving the cassettes a 10T-start for wider range (Up to 10-36, or 360%!). That means you can stay on the same ring longer, requiring fewer front shifts, which are inherently less efficient than rear shifts. And when a front shift is executed, the smaller jump is smoother and allows you to get to the right cadence with fewer compensation shifts in the rear. Fewer, faster front shifts make it easier for you to find the right gear, and that’s a distinct performance advantage relative to traditional drivetrains.

By starting X-Range cassettes with a 10T cog, SRAM's able to keep the cogs and chainrings smaller overall, eliminating the potential weight gain of a wide-range 11-tooth start drivetrain. It's the best way to expand range and keep small jumps between cogs.

More range, tighter jumps, and smoother shifts. What's not to love? With X-Range, getting everything you’ve always wanted in a drivetrain has never been simpler.
