Sram GX AXS

[Ypuh]

Definitely more excited about electronics coming to this price point than the product itself. Considering how much stuff they have to keep the same on electronic components vs mechanical I was really suprised with the $600 tag. Outside of a stamped steel cage and bearings any idea how they are getting the pricepoint down so much? Or is it more about time and electronic shifting prices are coming down?

Isn't the price point that low simply because you're barely getting anything? A shifter and a derailleur for €630. That's it. No brakes, no levers, no discs, no cranks, no chain, no cassette, no bottom bracket, no cables.

I find it ridiculously expensive, but appearantly SRAM did a smart move (again).

Just need to wait for Rival AXS shifters and possible to have a "budget" mullet for my gravel bike, not super WW focused for that bike

gx axs rd is optimised for 10-52 cassette, is it a little too much for gravel?

Optimizatized is kind of misleading. It doesn't mean works better with a 52t cassette, just means it can be used with a 52t cassette. You can still use this with 9-46 e thirteen cassette an eagle 10-50 or 10-52

As far as what gearing is right for you depends on what you're doing. No right or wrong choice

Would it shift as good as 10-52 if I pair it up with SRAM 10-36 or Rotor 11-46? It could be a good candidate for 1x Road.

No it can't be used with a 10-36. I believe the Sram website states 42 or 44 minimum.

10-36 could be okay, GRX is suggested as a minimum of 34T and I've ran it with a 25T and 28T fine

[ooo]

interesting combo is GX AXS RD + Shimano 10-45t -12-speed cassette (microspline/hypergrlide+)

10-45t 12s cassette = 11s cassette 12-45 + 10t cog
12-45 11s = --12-14-16-18---21-24-28-32-36-40-45
11-46 11s = 11-13-15-17-19-21-24-29-32-37-----46

10-36 could be okay, GRX is suggested as a minimum of 34T and I've ran it with a 25T and 28T fine

one grx rd is specced for 11-30/11-34, other one is 11-40/11-42

Shimano Derraileur and Sram are very different.. Sram states you can not go below 44 or 42 on any Eagle 12 speed derraileur.. I have all the Road and MTB AXS ranges, so I did try the 10-36 on my Eagle AXS RD with an Eagle chain and flat top chain and I can confirm is "does not" work.

I can confirm that the Eagle AXD RD works with e13 9-46 and 10-50 as well as Eagle 10-50 and 10-52 all working flawlessly with Eagle and KMC 12 speed chain.

A mountain bike magizine did a mismatched Shimano Sram setup like you proposed and found that is shifted ver very well.
The test bike was as follows: Eagle AXS RD and Shifter, Shimano 12speed Cassette, Chain and Crankset.. The reviewer felt that is married the smoothnes of Shimano shifting with the quickness and accuracy of Eagle AXS.

Note: this only works when you are using the Hyperglide + 12 speed chain, with shimano Cassette and approved HG+ 12 speed Chain Ring.. Shimano chain will not work well with Narrow Wide 12 Speed Sram Chain ring

A good read on mixing shimano 12 speed with Sram AXS (will work with new GX AXS as well)

cassette spacing 12s shimano/sram info - viewtopic.php?t=152690

bikemag tested 12s sram 10-5x rd with shimano 12s 10-5x cassette, how well it will work with 10-45 casseette is still unknown

shimano itself recommend to use 2 different RD:
for 10-51t casseette shimano recommend SGS derailleurs only: RD-M9100-SGS, RD-M8100-SGS, RD-M7100-SGS
for 10-45t casseette shimano recommend GS derailleurs only: RD-M9100-GS, RD-M8100-GS

When XT M8100 was released one year ago shimano suggested to use RD-M8100-SGS for both 10-45 and 10-51 (GS was only available as XTR)
but very soon they changed recommendations, and now 10-45T cassete is not recommended for RD-M8100-SGS
one year later (this month) shimano released addtional rear deraileur RD-M8100-GS just for 1x12 10-45T

Thanks for your effort. Do you have Rotor 11-46 to test? It's better for road use but I expect the middle range of the cogs shift worse than either ends...

I dont have the Rotors cassette, but from what Ive read here its 50/50 with people saying it shifts well and others saying its not smooth.

Currently running a 42/10-42 I could go to a 44/10-50 and have a more options at either end + when I'm sitting on the road I'm pretty low on the cassette so have a better chainline would be nicer too

[bikewithnoname]

So is anyone out there successfully riding a 12spd XT/XTR 10-45 cassette and a SRAM AXS RD?

[MattMay]

^+1 I’d like to know that too. Currently running a 42T chainring (ec90sl crank) in an AXS mullet...Force AXS + Eagle rd and 10-50. Don’t need the 50. A lighter tighter 12-spd cassette with higher low end would be great. By lighter I mean like 80-100g lighter. Was considering a Rotor and going 44 up front.
