Such a pretty sound.

 

Now I am considering getting one for my Shimano XTR machine - just not entirely sure if it will definitely be compatible???

Everything I have found is that it is compatible whether you use the mechanical group or AXS.

Thanks Mate,

 

There was some discussion about using the correct chain, which is the only part that comes into contact with the AXS other than the bolted connection (I think)

your chain is more in contact with your cassette (generating traction) than with your derailer (pulley wheels juste guiding your chain). I would stick to the XTR chain as long as you're on the shimano cassette, and then the day you go for a sram cassette get the XX1 chain.

 

BTW today I added a little more gap than the recommended 3mm at 30% sag on my shimano/AXS setup, shifting is smoother. I must be at around 4/4.5mm gap between the pulley wheel and the closest tooth on the biggest cog when the chain is on the 2ond biggest cog. Best setup I've had so far. I found it was a bit rough changing to harder gears with the 3mm gap

Thanks JBR,

 

Are you not lining up with the pulley axle centre as per the supplied tool?

The supplied tool doesn't fit on my XT cassette when the chain is on the 2nd largest cog

 

Not sure how it's supposed to fit between the cog and the chain on a sram system if the gap is the same between the two cogs...

 remember the SRAM cassettes are made of steel; so the thickness of the sprocket will be thinner than the alloy sprockets on the XTR cassette. There's also ramps and pins on the XTR cassette that will make the space between the sprockets smaller.

The distance between the centre of the top of the teeth from sprocket to sprocket is very similar across the Shimano and Sram products even though the gap isn't the same. That centre to centre gap is what makes it possible to use Shimano derailleurs and shifters with Sram cassettes and vice versa

Thanks for that DD

 

You’ve inspired me to order another one for my XTR shod bike. (Even got a better deal)

 

Hope to have it in hand and installed before our trip to Clarens next weekend. ????????????

I ordered a second one for my Stumpy and installed it at 23:30 for a ride the next morning hahaha... the AXS units work so well. I barely had to do anything (I replaced a normal GX Eagle derailleur).

Did the GX AXS upgrade last week.

Impressed beyond measure.

Survived Cape Munga Grit...40 hours of torture.

No issues with the shifting, and the battery is still good.

so the battery lasts longer than the stated 20 hrs?

 

It depends on how much you shift. I am guessing a trail ride where you are up and down the gears the whole time will yield shorter than 20 hours, long gravel rides where you sit in a gear for a while will yield longer hours. 

 

I am on 16 hours now (trail riding), and my battery is showing more than 50% left. I will ride it this week to see how long it still lasts, but have an event this weekend - so not gonna try my luck and will charge the night before. But so far it seems like it will last longer than stated. 

 

Temperature will also influence battery life.

carefull with the battery readings though hey, I changed my shifters battery on my eTap AXS, and two days later my garmin told me battery was critical. Then later on it said 100%.

 

But the deraillers battery the reading should be a bit better. I wouldn't take chances though especially considering you only carry one battery with on the MTB unless you also have a wireless dropper.
