SRAM just announced that their eTap AXS family now includes Rival. That’s big news for riders who may not want to pay top dollar for a drivetrain, but still want premium performance. But what does a more affordable wireless group mean for the gram scales? Of course we have the answer…

Shifters and Brakes

Along with a complete build that will be reviewed soon, SRAM sent over a complete group to pop up on the scale. Starting with the wireless shifters and disc brake calipers and hoses, we see 390g for the front and 411g for the rear. Obviously, this will vary slightly based on the needed hose length for your bike.

Rear Derailleur

The rear derailleur checks in at 342g without a battery. Since there’s only one derailleur for the Rival group, this is for 1x or 2x drivetrains and will fit up to a 36t cog in the rear.

Front Derailleur

The front derailleur weighs 151g, again without the battery. The front derailleur also comes with a clever little guide tool for the perfect set up. Line up the chainring with the slot in the tool, and it seems like the perfect angle and height is almost guaranteed.

Battery

Obviously, you won’t get any shifting without some batteries. Two of them will add 49g.

Crankset

For the crankset, we weighed a 175mm 2x Wide crank with the Quarq single sided power meter installed. In total, you’re looking at 863g for the crankset + power meter, with the individual components broken down above.

You’ll notice an additional plastic ring on the scale above – that’s a ‘chain jam guard’ which is only for the 30t rings. This plastic guard prevents the chain from jamming into the gap between the crank and the BB shell on certain frames where that could be disastrous if there’s ever an inboard chain derailment. The guard is available as an aftermarket part and came preinstalled on this crankset.

Cassette

For the cassette, we have SRAM’s largest option with a 10-36t 12 speed cassette. Like other eTap AXS cassettes, it requires an XDR freehub body and it weighs 340g.

Chain

A more affordable Flattop 12 speed chain will likely be celebrated by all eTap AXS users, not just rival. The lack of hard-chromed inner plates makes keep the price down, and the weight at 272g for the full length chain.

Miscellaneous

Last up, we have a few different brake parts to complete the set up. We have a front brake caliper adapter that can be used for 140 or 160mm rotors, a rear 160mm adapter, the Paceline Centerlock rotor in 160mm, and a Zipp Centerlock ring for thru axle hubs.

Stay tuned for a full review of the group very soon!

  1. A Red AXS shifter and brake w/ hose is 391 (233+158) grams as measured by Bikerumor, so the weights are virtually identical.

  2. Nice looking stuff.

    That front derailleur setup gauge is a great little part. Most of the ones I see are way poorly done. Although, I suppose I probably just take note of the mistakes.

  3. The setup gauge looks to be a great aid but again, the bike industry missed the boat. This part could have easily been made from a hard recycled cardboard source rather than plastic. It is at the imagining and engineering stages where new processes and materials must be introduced. Instead, the cheapest and easiest material was used with no apparent consideration given to the impact on the environment. Yes, it’s a small part but when is the bike industry going to make a concerted effort to become more earth friendly. I shudder to think of how much throw away plastic is used in the packaging.
