Red eTap AXS 2x HRD Groupset

As soon as we heard the rumors and saw the spy photos, we knew right away we had to snatch up SRAM's latest version of its Red eTap AXS 2x HRD Groupset. We were already pretty enamored with its original 11-speed version and its simple shifting logic, but with more and more drop bar bikes venturing off the beaten path, SRAM added some meaningful updates to its electronic group. The end result is an intuitive groupset that adds another cog, makes us totally rethink current gear ratios, allows for customization, and is better suited for all-road, gravel, and cyclocross bikes. That's not even mentioning how easy it is to set up and travel with since there's no cables or wires to deal with.

This group includes right and left Red eTap AXS HRD brake/shifters with flat or post mount calipers, two 160mm Centerline XR 6-bolt disc rotors, front and rear Red eTap AXS derailleurs with batteries, a battery charger, and a cord.

One of the most exciting new features with the group is its AXS integration. Once you connect the group to the AXS app via Bluetooth on your smartphone or tablet, you can easily personalize the groupset including button customization, numbers of up or downshifts when the buttons are held down, as well as sequential and compensating shifting. Sequential shifting reduces redundant gear ratios and maintains a better chainline by automatically shifting the front and rear derailleurs to the optimal gear as you up and downshift, allowing you to focus on the ride. This option is great for those already used a 1x setup. In this mode, however, you still have full control over the front derailleur to shift as needed. Compensating shifting simply shifts the rear derailleur to a self-selected number of shifts after making a front shift, so your change in cadence isn't drastic. This is something we already do with mechanical shifting but it's nice when the system's electronics can do it for us.

The new RED eTap AXS front derailleur returns with SRAM's excellent Yaw pivot design for trim-free cage operation. It rotates slightly when shifted into the small ring improving shifting while also preventing chain rub, no matter where it is on the cog out back. It also features an optimized cage profile for the new close-ratio (33/46, 35/48, and 37/50) X-Range front chainring combinations for smooth and quick shifting. Made from a combination of aluminum, steel, and composite, it offers the best durability and the lightest weight. It's completely compatible with existing eTap batteries and gravel riders rejoice: its battery placement is streamlined to allow for more rear tire clearance which SRAM claims is up to 700c x 42mm.

The rear derailleur also gets some exciting changes namely in its Orbit fluid damper chain management system providing a quiet, secure, and smooth ride, even over the bumpiest terrain. It also receives a new motor and signal for faster, more precise shifting and like the front derailleur, remains compatible with existing eTap batteries. One last thing, it uses the same cage length for 10-26, 10-28, and 10-33t cassettes so you can make changes to your gearing based on the terrain, all while using the same rear derailleur.

Please note to complete the groupset, you will still need to purchase a crank, bottom bracket, cassette, and chain.

Love this groupset. Shifts fast!

Using both levers is genius. Just makes more sense. No more accidentally down shifting. Clean looks and battery lasts for a long time. I have the 1x and the 2x. Don't listen to chi4419626. He has poopy pants and doesn't like change. He still has a flip phone.

Cool concept needs work in reality

I just bought a Wilier with this group. I was really excited about it but have been disappointed so far. I have two main complaints. 1)the shift levers pivot is too low. I wrap my fingers around that portion and if you get skin wedged in there rough roads can cause occasional pinching. 2) two lever shifting for the rear derailleur. Who thought that was a good idea? Using one hand (or finger) is so much easier.

I have had the 11 sp eTap and now I have the eTap AXS......I think they are both outstanding systems. to your pinching, we are all different but I have never had a problem with either system. As to the two lever shifting for the "rear" derailleur, I believe you mean the "front". I personally love the two lever shifting, as with gloves on, it is difficult to feel the Shimano levers, and, you don't have to think about which lever to push for big ring or small!

Update: Gregory, No I meant it requires both levers to shift the rear derailleur. That's moronic. As is the pivot point on the brake lever. Now that I have had a couple of months on this group I am less impressed than initially. I shouldn't have rushed to disc brakes. Through axles, compatibility and adjustment of the brakes are a royal pain in the a$$. My expensive Wilier with this group weighs well over 17lbs(i have a 4 year old merlin empire that weighs under 15). Disc brakes and new 12 speed groups arent ready for prime time.

Update 2: now that I've pointed out what I dislike i feel to be fair I should point out the positives. -I love gearing. The smaller 44 tooth chain ring coupled with the big 12 speed rear gears make small chain ring almost pointless. Only in the steepest climbs will you need the little ring. I climb comfortably long 6% grades in the 44. -the battery life is far better than I anticipated. I charge the batteries every three weeks. Plus if the rear battery dies you can just swap with the front derailleur battery in two seconds. -the built in power meter is excellent -the shifting is crisp -brakes are also excellent

I am have both Di2 and eTap and I like the 2 lever shifting way better since I shift the front derailleur way less than the rear.

Regarding #2, it doesn't have to be that way. By default, pressing both levers toggles the front derailleur, not the rear. The AXS app let's you customize what happens.

Corey S and Gregory G - I believe what he’s talking about is the fact that the right hand lever shifts to a higher/harder gear and the left hand lever shifts to a lower/easier gear. whereas with the Shimano system the right hand lever shifts up and down the rear cassette and the left hand lever shifts up and down the chainring. However my understanding is that this is still something that can be changed using the Phone app. The way I understood it, it could be set up so that the right hand lever shifts up, left hand lever shifts down, and it automatically manages when to shift the chain ring. Or, you can set it up so that the right hand lever shifts up and down the rear cassette, and the left hand lever shifts up and down the chain ring. Or, if you’re using a 1X set up, you can set it up so that the right hand lever shifts up and down the cassette, and the left hand lever actuates a wireless dropper post
