SRAM Rival eTap AXS drivetrain brings trendy wi-fi shifting to riders of all ranges


SRAM Rival eTap AXS is right here. Shock? It didn’t take a crystal ball to determine what is likely to be subsequent within the eTap AXS pipeline, but it surely looks as if SRAM’s latest highway group will probably be definitely worth the wait.

However why add wi-fi shifting to what’s primarily SRAM’s entry level for efficiency highway and gravel teams? SRAM says that it’s all about bringing the newest improvements to riders of all ranges whereas lowering complexity and eradicating boundaries – primarily they simply need to make a greater trip for all.

Relating to drivetrains, in SRAM’s opinion, cable actuated shifting simply doesn’t supply a using expertise on the identical degree as trendy bike frames. To handle that, they’ve simply introduced Rival eTap AXS which presents an analogous using expertise to RED and Power together with wi-fi shifting, eTap shift logic, an built-in Energy Meter possibility, AXS connectivity & insights, and hydraulic disc brakes.

The SRAM AXS app additionally gives Low battery alerts, different shift modes, management customization, energy and gearing insights, and simple firmware updates, all straight out of your telephone.

Finish of Rival Rim Brakes?

Notably, Rival will now be wi-fi and hydraulic disc brake solely. That’s proper, no extra mechanical Rival 2x teams, and no extra rim brakes. Nonetheless, SRAM will nonetheless supply RED and Power eTap AXS with a mechanical rim brake possibility – you simply received’t discover it on the Rival degree.

SRAM additionally states that Rival eTap AXS 1×12 successfully cannibalizes Power 1×11 mechanical. However, Rival 1×11 mechanical and Apex 1×11 mechanical will nonetheless be provided, having not too long ago had their finest years but.

Nonetheless Totally Wi-fi

In contrast to a few of the competitors, SRAM Rival eTap AXS is absolutely wi-fi. Which implies like different eTap wi-fi teams, every element should have its personal battery. Fortunately, SRAM Rival eTap AXS will use the identical batteries and chargers as RED and Power eTap AXS.

The rechargeable battery packs disconnect from the entrance and rear derailleur, and are charged in their very own USB dock. Full bikes and teams will embrace a single charger, however if you wish to cost a number of batteries without delay, you possibly can choose up a further charger for $40. And when you handle to lose a battery, or desire a spare, these are $55 every.

Because the battery packs could be too massive to slot in the shifter and so they don’t want as a lot juice, every hood features a CR2032 coin cell battery saved in a compartment underneath the lever. Battery life on these will rely on how typically you shift, and trip, however on my Power eTap AXS check group, I’m happening two years now with the primary batteries.

Smaller Hoods for Smaller Palms

Whereas we’re on the subject of shifters, the form of latest Rival eTap AXS hood is likely one of the most noticeable modifications for the complete group. In comparison with the hoods of RED and Power, the Rival hoods are a bit shorter, and about 10mm smaller in diameter on the narrowest level. The result’s a hood with elevated finger wrap and improved attain to the lever for these with small fingers.

A part of making the hoods smaller is the elimination of the port for Blip or Clics. If you would like these, you’ll have to make use of Power or RED shifters. The shifters additionally lose the pad contact level adjustment of RED and Power, however preserve the lever attain adjustment. The levers themselves make the transfer from carbon to extra inexpensive aluminum for Rival.

Rival’s braking design is equivalent to Power and RED on the lever, however RED and Power calipers embrace SRAM’s Bleeding Edge snap match bleeding port. Rival retains the price down with a standard threaded port, however nonetheless makes use of Bleeding Edge bleed course of.

There are not any Rival-specific brake rotors, so our check bike got here outfitted with the Paceline Centerlock rotors from SRAM.

As talked about, Rival eTap AXS will solely be provided with hydraulic disc brakes, with flat mount calipers. Don’t have a body with flat mounts? SRAM will nonetheless supply a publish mount disc caliper and hose equipment on the RED degree. It’s also possible to use SRAM Degree disc brake calipers with the Rival eTap AXS shift levers.

The brake pads are held in place by the same old threaded pin with a c-clip, and the pads seem like a special form than these used for Power eTap AXS (we’re within the means of confirming any inter-compatibility between the pads). Brake pads will probably be provided in each natural and sintered compounds.


Talking of inter-compatibility, you is likely to be questioning whether or not SRAM Rival, Power, and RED eTap AXS share any compatibility between teams. The reply is sure, however not for the whole lot. Variations in derailleur capability, and gearing might make some elements incompatible, however “12-speed Flattop chains, 12-speed cassettes from 10-28T all the best way as much as 10-36T, 1x cranksets, 2x cranksets (remember to use the right broad spindle crankset with the broad model entrance derailleur), shifter controls, and energy meters” are all appropriate by the completely different teams.

Street? Gravel? Large Crank & FD choices enable for both

SRAM doesn’t have a gravel-specific groupset, and that continues with Rival eTap AXS. What they do have although, is a Large model of the entrance derailleur and cranksets primarily based round a wider chainline and wider stanced arms to clear greater frames and tires.

Entrance Derailleur

When you go for one of many Large cranksets, you’ll have to match it with the Large entrance derailleur as properly. Due to this, there will probably be two completely different entrance derailleurs provided – the FD-RIV-E-D1, and the FD-RIV-EW-D1 (Large). Functionally, they’re the identical, however the usual FD is supposed for the 46/33t or 48/35t chainring combos. The Large FD is supposed for the 43/30t Large chainring combo, and will supply clearance for as much as 700c x 45mm or 27.5 x 2.1″ tires.


SRAM Rival eTap AXS cranksets

There are fairly just a few choices for cranksets, however they boil right down to 1x or 2x, normal or broad, and with or with out energy meter. All the cranksets are designed with polished aluminum arms, and run on the DUB backside bracket system. All the cranksets additionally use a 13t hole between the 2 rings to take care of their X-Vary gearing development.

Customary cranks will probably be provided in 48/35t and 46/33t double configurations solely. The Large cranksets will are available in a 43/30t double, or the brand new Rival 1 Large crankset with 38, 40, or 42t chainrings. Word that the Large cranks are appropriate with 135, 142, and 148mm Enhance rear spacing which is vital when you think about the Rival/GX Eagle mullet construct choices which at the moment are potential (and within the works).

The 2x cranksets use a 107mm BCD for the usual spindle cranks, and a 94mm BCD for the 43/30 Large spindle crankset, every with particular chainrings that match the profile of the crank.

SRAM Rival eTap AXS 1x crankset

The 1x cranksets then again use a direct mount chainring. Customary cranksets use a 145.5mm q-factor and 45mm chainline, and the broad spindle cranks bump as much as 150.5mm and 47.5mm.

Since Rival cranks will solely be provided with DUB spindles, they’re not appropriate with BB90 backside brackets. In that case, you’ll want to make use of one of many SRAM Power or RED cranks which can be found with GXP spindles.

Single Sided Energy Meter

Cranksets can even have the choice for an built-in energy meter – made potential by the brand new single sided design. The spindle-based possibility is a brand new design from Quarq that’s fairly gentle, including simply 40g to the bike. The one sided nature means it solely measures the left leg solely, so it’s in all probability not as correct because the Power or RED energy meters, but it surely’s inexpensive and powered by a single replaceable AAA battery. Each BLE and ANT+ appropriate, the ability meter has an IPX7 waterproof score and might be up to date by eradicating the interior ‘sled’ from the bike.

All the cranksets will probably be provided with an influence meter possibility, and there can even be the choice of upgrading to the ability meter sooner or later. Say you acquire a motorcycle with a Rival crankset that doesn’t have energy? You possibly can improve to energy by changing the non-drive arm and spindle meeting with the pre-installed energy meter for $250.

One Rear Derailleur

SRAM Rival eTap AXS rear derailleur

Fortunately, there’s just one rear derailleur to select from. Each 1x and 2x teams will use the brand new RD-RIV-E-D1 rear derailleur. Constructed with a 36t most cog capability, the derailleur is appropriate with cassettes starting from 10-28 by 10-36, SRAM factors out that the derailleur is not appropriate with the 10-26t cassette (which is not like for use anyway).

To maintain tabs on the chain, the derailleur options mechanical spring clutch. That’s in comparison with the Power and RED derailleurs which use the extra compact and lighter Orbit Fluid Damper. Constructed with all aluminum plates, the cage homes X-SYNC pulleys.

Gearing Choices

SRAM Rival eTap AXS cassette options

Again on the cassette, SRAM’s X-Vary gearing idea presents larger vary with what they declare to be higher steps, utilizing tremendous broad cassettes and narrowing distinction between chainrings. Meaning SRAM stored Rival 12-speed cassette choices to simply two selections, the 10-30t, and 10-36t. The 10-30t cassette has 300% vary – greater than an 11-32t, and 6 consecutive cogs on the small finish of the cassette. The 10-36 is probably the most broadly speced thus far although, with 360% vary in comparison with an 11-34 which is just 309%.

The purpose is that SRAM says their 2×12 or 1×12 Rival eTap AXS arrange can be utilized for something – Race, Endurance, and even Gravel. They level out that it presents decrease gearing than GRX, with out the necessity for a devoted group.

SRAM Rival eTap AXS XDR cassette

Like the remainder of the eTap AXS cassettes, the Rival cassettes makes use of SRAM’s XDR freehub physique.

Flattop Rival Chain

The final piece of the puzzle is the chain. Like Power and RED, Rival eTap AXS requires a Flattop 12 pace chain. The CN-RIV-D1 makes use of the identical Flattop design that has an uneven design with a flat prime and spherical backside, in addition to a directional Flattop PowerLock. Variations for the Rival chain are discovered within the building with RED and Power chains getting hard-chromed pins, rollers, and inside chain plates whereas Rival chains solely use hard-chromed pins and rollers.

SRAM Rival eTap AXS compatible chain tools

Like Power and RED chains, you’ll want a Flattop appropriate chain device to put in it (together with appropriate grasp hyperlink pliers, and chain put on instruments). SRAM has an inventory of appropriate instruments on their web site, but it surely’s not an exhaustive checklist. Living proof, the Wolf Tooth Elements 8-Bit and normal Pack Pliers at the moment are each appropriate with SRAM Flattop chain hyperlinks (each can even retailer spare Flattop hyperlinks as properly).

Pricing & Availability

At a time with restricted availability of nearly the whole lot, SRAM has the brand new Rival eTap AXS obtainable right this moment. In addition they anticipate that Rival eTap AXS will greater than double the variety of AXS bikes at present out there.

As anticipated, that is probably the most approachable eTap AXS group but, with the bottom price ticket. Key single element costs embrace $30 for the chain, $125 for the cassettes, $255 for the rear derailleur, $175 for the entrance derailleur, and $349 for a crankset with energy meter.

Group Pricing

  • $1639 for 2x group with energy
  • $1420 for 2x with out energy
  • $1409 for 1x with energy
  • $1190 for 1x with out energy

A groupset contains: Shift-brake system, rotors, crankset, backside bracket, chain, cassette, derailleur (entrance and rear for 2x, rear just for 1x), batteries, charger.
