AXS XPLR on road/all road
Without wishing to start a controversial thread about 1x for road, has anyone had any experience running AXS XPLR on a (mainly) road bike? I'd be contemplating a 42 or 44T up front. The bike would see mainly solo, mainly road riding, but would see some light gravel and maybe a quick-ish group ride occasionally.

I tried 1x SRAM on a road bike several years ago, but it wasn't AXS. I also currently have a Specialized Crux with 1x13 Ekar (38T chainring with a 9-42 cassette).
Looking at the XPLR cassette, it looks like it has a 1-tooth jump only in the smallest two cogs. The biggest issue for me when I tried 1x11 SRAM was the big jump between the cogs. It really bothered me on the road as I found myself wanting to be in between cogs to maintain my desired cadence. It seems others are less sensitive to this. The Ekar cassette fixed that issue with the smallest six cogs being 1-tooth jumps, so I have been enjoying that a lot more when I ride that bike on the road. I also find 38T-9T to be plenty big as my highest gear (4.22:1 ratio), especially when combined with larger tires.

I did a 125mi ride with a group a few weeks back on a 42x10-44 and it worked just peachy. If you just need the gear range at the top/bottom end and can accommodate that with the XPLR setup, then 1X certainly is an easy way to go.. I never would have said that until I tried it. You'll get many armchair opinions here, most of them untested and uninformed.

I find an even greater range acceptable with my mullet AXS 42 10x50 currently riding 700x38mm mostly on the road. I’d imagine as long as you are happy with the min and max then you are good to go.

I didn't mind the cassette jumps, but on frames with shorter chainstays, the chain angle gets to be a bit extreme, and makes things noisy in a lot of gears.
I haven't seen Sram frame fit specifications for "road" specifically. I know for their 12 speed mountain groups they don't advise shorter than 425mm chainstays. For their 12 speed road group, they don't advise shorter than 395. In my own personal experience, for XPLR I'd lean closer to the MTB requirement than the road requirement. Wouldn't use it on anything shorter than 415mm chainstays myself.

I had my road bike set up with Rival AXS 1x with a 46-tooth front and 10-36 cassette for a while and it really did hit everything I needed. It's maybe a little bit undergeared if you're doing a lot of sustained climbing, but for everyday riding it fit the bill. Going to XPLR would leave bigger gearing gaps, but that has never really bothered me, but it does bother others.

I use AXS Force 44T 11-36 on my road bike, and it works great. The 12 cogs make agreeable steps and a gear range similar to a compact double. It runs quiet and stable.
10-44 lives on another (gravel) bike, but that range would work nicely for steep road terrain. Last edited by sparky33; 08-16-2022 at 12:20 PM.

I have a Force AXS All Road MRB bike set up as a 1 x 12 and I like it very much. It's got 40T front and a 10-36 cassette and the gear range for my dirt/gravel roads is just right. I don't have any issues with the size of the gear jumps at all...I wouldn't road race it with such jumps but they don't detract from the joy of riding it whatsoever.
It's a simple and elegant thing and I like it a lot. dave

I currently using 40x10-42 SRAM 11 speed on my road bike (cyclocross bike, with road tires).
It's fine for most things. But, the gaps between gears can be annoying on longer/faster group rides and 40x10 also leaves me spun out on descents. I have 2x Force AXS on my gravel bike and like it. I'll likely swap the road/cross bike to 2x this off-season.

I am answering the same question. Just got my Force groupset in the mail I am going with 44T front and 10-44 in the back. Could not decide between 42 or 44 up front but will report back in coming weeks. Excited for first electronic groupset and not having to worry about thinking what gear I am in

OP, I haven't used AXS XPLR but I have run 1x on road and it's fine in a lot of cases. I found the chain ring size to be a primary point of test & learn. 42t was a sweet spot for me.

All my road bikes are set up with SRAM AXS Force 1x. One set up is 44 chainring with 10-36 cassette. The other is 46 chainring with 10-44 cassette. I live in a hilly area and have no issues. Maybe, Ekar 13 speed could improve on this setup but I prefer electronic shifting.

I agree though. A 38T w a 10-50 is bikepacking-only to me.. whereas a 44-46T with 10-44 is spot-on for normal road riding - and dropping to a 42T is great for all-road/gravel and anywhere with lots of steeps.

Chainstay length could be a issue when running a mtb cassette on a short stay road bike. No issues with 10-44 XPLR cassette. 1x noise will be slightly louder than 2x because of chainring teeth. I run 10-44 on a 410mm chainstay bike with no issues. An additional thing to consider with 1x is the use of oval chainrings. I just started using a 46t oval ring with none of the issues that 2x oval set ups have.
