Born from the ability to mix and match certain AXS road and MTB components, the SRAM Rival GX Eagle eTap AXS Mullet HRD Groupset pairs SRAM Rival eTap AXS HRD shifters with a GX 12-speed rear derailleur and wide-range 10-52t cassette to conquer gravel steeps. Robust and durable, this groupset is made to go the distance and delivers the precision of wireless shifting at a previously unseen pricepoint.
Fully customisable through the accompanying SRAM AXS app, shifting can be set up to suit any preference. The Rival eTap shifters are ergonomic in their design and built to offer lasting comfort on longer rides. They feature textured shifter paddles to enhance control and offer tactile shifting across the entire 12-speed range. The Rival DUB crankset is built for exploration and is compatible with a range of rear hub spacing options.
The GX AXS rear derailleur is feature-packed and offers stress-free pairing to the Rival eTap shifters. Shifting is consistent across the 10-52t cassette, and an overload clutch prevents damage to the cage by instantaneously disengaging upon impact. The hydraulic disc brakes deliver exceptional power and confidence on the descents, offering consistent shifting through a range of weather conditions.
Great group set! Business up front, party in the rear apparently. The range is probably far more than anyone realistically needs (the 52 tooth cog is sooooo big) but it’s there as the ultimate nail out on the steepest hill when you are the most laden. Wireless is really easy to set up too. All in all very pleased!
As a rider who already has a SRAM mullet groupset (Eagle XX1 and SRAM Force mix) on my Evil Chamois Hagar, I was looking for the same but on a lower budget for my new Ti gravel bike. After a quick Google I found Sigma had the Rival GX mix groupset in stock so went for it. I'd used Sigma in the best and I'm always impressed with their stock and how quick they deliver. Once received I got to work on install the groupset on my new frame. One ride later and I'm blown away with how great SRAM AXS is, I'm a total convert! Super easy to install and set up, and a dream to ride.

Founded in Chicago in 1987 with a single product — Grip Shift — SRAM has spent four decades reinventing how riders interact with their bikes. From the first wireless electronic groupset to today's AXS ecosystem, the brand keeps asking the same question: how do we make the next ride better?
Wireless. Configurable. Ride-aware. SRAM's AXS platform replaces a tangle of cables and proprietary protocols with a single, app-driven ecosystem that spans road, gravel and mountain. Components talk to each other and to you.
