Reviews over the

SRAM XX1 Eagle AXS 12-Speed Upgrade Kit

I haven't tried it yet

I fitted an axs groupset on my first mountain bike and I can't go back. I've fitted my Vae in the same way for the prediction, the fluidity and the speed of gear changes.

Best mountain bike product tested to date.

Pros & Cons

Shop on the perfect page. Simple menu and easy to find what you are looking for. Fast and hassle free shipping. Quality product.

Very good product. Fast and effective shipping.

The product was delivered promptly as expected, but the box containing the derailleur and the one containing the joystick were not blister-packed, raising doubts about the product's novelty.

Pros & Cons

Truly excellent not only to use but also just to look at

Pros & Cons

At first I was really pessimistic about electronically shifting. But while getting in touch with the electronic shifting I like it.

Pros & Cons

Perfect purchase, fast and safe. Very well packaged and with good presentation. The group meets the expectations. It is a great product for a mountain bike. I am delighted with it. After several months of use I have had no problem. The battery lasts much longer than expected. The shifting is fast, easy and reliable. With the app you can get data to help your pedaling.

Pros & Cons

Fast handling throughout as always.

Pros & Cons

Nach Umbau von Shimano XTR 2x11 auf Sram xx1 Eagle AXS, keine ratternde Kette am Umwerfer mehr, Schaltvorgänge fast geräuschlos.

Very quick to install and adjust, very smooth and precise operation

Pros & Cons

Install Connect and drive. Wonderful stuff

Pros & Cons

Very simple installation. Works immediately without major adjustments

Pros & Cons

Det bedste gearskifte penge kan købe, eneste anke er at der kræver lidt at vænne sig til controlleren ift. almindelig skiftegreb.

Pros & Cons

I already have the SRAM Red on my road bike and I'm delighted but I have to say that the XX1 is more impressive.

Great fun new toy for MTB ! and works perfectly! No more problems with cable stretch, intermediate adjustments etc.

Pros & Cons

A pleasure to shift, always right once everything is adjusted but is very easy, only I would opt for the rocker pedal which feels more natural, what we are used to as a mtb

Pros & Cons

Still working flawless after 2 years of use. will never go back to mechanical.

Pros & Cons

After buying the XX1 Axs groupset, I'm really enjoying it. There's not a sound on the bike and the gears shift perfectly. It feels like a top-of-the-range bike, even though I used to have an Xo1 groupset. I'm not about to go back

Pros & Cons

Perfect service

Runs great

Pros & Cons

Super fast conversion kit

Pros & Cons

Shifts great and very easy to fit and adjust

Pros & Cons

Question: Does this lit not come with the plastic "gauge" to measure the distance to the big sprocket?

Swap for a GX launcher was ready in 30 minutes without changing the chain length

Pros & Cons

The buying experience was great, the stuff even better :)

Pros & Cons

This is the first time I've fitted a derailleur myself. It was a breeze and easy to setup. Being Bluetooth my handlebars are now very minimalist with just brake hoses and the AXS controllers. Out on the trails, the shifting is soo accurate and fast. I upgraded from an X1 which was good but this is another level. My second bike will be treated to AXS stuff next. The ANT+ side of things allowed me to pair it to my mega C so I also have battery life and gear displayed.

Pros & Cons

To upgrade my emtb with sx circuit.

I advise everyone... another world with 29" wheels.

Pros & Cons

the best wireless system you can buy. Would be 10/10 if you could adjust easily on the move.

Pros & Cons

Pros & Cons

Bought this kit along with the XX1 cassette and chain combo, as an upgrade from Hope's 11-48 11speed cassette and SRAM shifter etc. Very easy to pair the components, took some time fine tuning the shifting but it's silky smooth and silent now. The rear derailleur is much larger than an 11spd I was using so was quite concerned on the first few rides on tight singletrack it would suffer. Fortunately not a mark on it...so far :) I may just put some protective tape over the most exposed edge just for peace of mind. I did have a grinding noise at first and I thought this was due to the chain being too short but it was actually my front chainring was in need of replacing. Changed it out and no more noise. The 3rd "button" is really useful as you can just nudge it to change gear will hammering the pedals. After a few weeks of riding I'm so glad I made the switch, effortless shifting and quiet drivetrain even on the 50T.

Pros & Cons

Impressive well made piece of engineering. Easy installation with no cables or wires. Pairing and setting up straight forward but some differences to manual Sram gearing set-up. Installed on an ebike so used app to set-up single indexing. Finding that changes are quicker and smoother especially going "down" the cassette. Early days yet to comment on long term reliability but no issues so far with some 150 miles done.

Pros & Cons

Well worth the upgrade from 11 speed xx1
