SRAM Rival AXS HRD Shift-Brake System — Front & Rear • State Bicycle Co.

Wireless shifting and hydraulic disc braking, front and rear, in one box.

This is the complete control package for a SRAM AXS road or gravel build: left and right shift-brake levers, both hydraulic calipers, and pre-bled hoses. Bolt them on, pair them to your derailleurs, and ride.

Rival is SRAM's entry into the AXS ecosystem, but "entry" is doing a lot of misleading work in that sentence. It shifts with the same wireless protocol, the same app, and the same eTap logic as RED. It just costs a fraction of it.

The hoods are the story

SRAM redesigned these controls around one problem: braking from the hoods used to take real effort. Moving the brake lever pivot higher changed the leverage ratio, and the result is roughly 80% less hand force to stop from the hoods than the previous generation.

If you ride on the hoods most of the time — which, on gravel and endurance road, is most people most of the time — that's not a spec-sheet improvement. It's the difference between one-finger braking and grabbing a fistful.

The redesign also closed the gap that used to pinch fingers under hard braking, and widened the Reach Adjust range so smaller hands can actually get to the lever without a shim kit.

How eTap shifting works

If you've never ridden AXS, the logic takes about thirty seconds to learn and then disappears:

Right paddle — harder gear
Left paddle — easier gear
Both at once — shifts the front derailleur

No cable tension. No trim. No indexing that drifts out over a season. The levers talk to the derailleurs wirelessly, and every shift is the same shift whether it's the first ride or the two-hundredth.

AXS app

Pair the system to the SRAM AXS app and you can check battery levels on every component, reassign what each paddle does, set up sequential shifting on a 2x setup, get service reminders, and push firmware updates. Reassigning buttons means a left-handed rider, a rider who wants the paddles reversed, or a 1x build can all set the system up the way they want in about a minute.

What you get

Left shift-brake lever with front flat mount caliper, 850mm hose (PN 00.7018.569.003)
Right shift-brake lever with rear flat mount caliper, 1500mm hose (PN 00.7018.579.004)
Carbon brake levers
Textured shift paddles and hood covers
Steel-backed organic disc brake pads, installed
Mounting hardware

Check your hose lengths before ordering. Hoses measure 850mm front and 1500mm rear. That covers most road and gravel frames, but if you're on a large or XL frame, running full internal routing through the headset, or building an unusual cockpit, measure your existing hose runs first. You can shorten a hose. You can't lengthen one.

Rotors are not included and are sold separately. SRAM recommends Paceline rotors for this system; Centerline rotors also work.

What you'll still need

This is the control end of the system, not a complete groupset. To finish the build you'll need:

An AXS rear derailleur — Rival, Force, RED, or XPLR
An AXS front derailleur if you're running 2x
AXS batteries and charger for the derailleurs
Cassette, chain, crankset
Disc rotors

Mixing tiers is fine. Rival levers run a Force or RED derailleur without complaint — they all speak the same wireless protocol. Plenty of good builds pair Rival controls with a nicer derailleur.

Batteries

Two separate systems, and people mix them up constantly:

The levers run on CR2032 coin cells. They last a very long time — think years, not rides — and you replace them at any drugstore.
The derailleurs run on SRAM's rechargeable AXS batteries, which are interchangeable front to rear. Not included here, because the derailleurs aren't either.

Fitment

Brake type: Hydraulic disc (HRD)
Caliper mount: Flat mount
Bar compatibility: Standard 31.8mm drop bars
Derailleur compatibility: Any SRAM AXS road or gravel derailleur
E-bike: Approved
Not compatible with mechanical SRAM, Shimano, or Campagnolo drivetrains

Flat mount calipers only. If your frame or fork uses post mount, this won't bolt up without a converter, and post-mount conversion on a flat mount caliper is not a clean solution — order the post mount version instead. Rotor size adapters are frame-specific and sold separately.

Installation

The hoses arrive pre-bled, which removes the ugliest part of a hydraulic install — but you'll almost certainly need to cut them to length for your frame, and cutting means re-bleeding that line. Budget for a bleed kit and mineral-free DOT fluid, or hand it to a shop.

Pairing is done by pressing the AXS button on each component. It takes about a minute and doesn't require the app, though the app is worth setting up anyway.

Full installation documentation, torque values, and bleed procedures are available in SRAM's service hub for this model.

OE product information

Not intended for retail sale. This is original-equipment product supplied for dealer service, warranty replacement, and complete-bike build applications.

OE product is the same component that ships on complete bikes — identical specification, identical performance. What differs is how it's supplied:

Plain bulk or poly packaging rather than a retail box
No printed manuals or quick-start guides — all documentation is available free from SRAM's service hub, linked above
No retail hang tags or display materials
Small-parts and hardware content may differ from the retail pack
Hose lengths are cut to OE specification and are shorter than the retail pack
Components may show minor handling marks from bulk packing

Warranty. SRAM's consumer warranty program does not apply to original-equipment components. Warranty and defect claims on this item are administered by State Bicycle Co. Contact our support team with your order number. Crash damage, wear items, and installation damage are not covered.

If you want factory-sealed retail packaging with the full retail small-parts kit and SRAM consumer warranty coverage, order the retail-pack version instead.

Original equipment service item. Supplied in OE packaging for dealer service, warranty replacement, and complete-bike build applications; not a retail-packaged consumer product and not intended for retail sale. SRAM consumer warranty does not apply to original-equipment components — warranty administration on this item is provided by State Bicycle Co. Professional installation required. Hydraulic disc brake systems require correct hose routing, cutting, and bleeding; improper installation can result in brake failure, serious injury, or death.
