Can anyone tell me if t-type will work with my new heckler sl s build without having to purchase a new cassette? The cassette on it is SRAM xg 1275 10-50t

Would like to upgrade but the full upgrade kit price is grim

You’d need the cassette for the system. It’s designed around standard distances and tolerances.
I bought mine in pieces because you don’t need new crankset or chainring for it. The chain is actually compatible with Shimano chainrings

It works
Just need to put a 2.5mm spacer between casette and freehub body.
My actual set-up is (see post #73):
XX1 Axs shifter pod
XX Axs T-type 00.7518.161.000 Mech
XX1 xg1295 10-50T cassette
XX1 Eagle 12s chain
and it's working with no problems since December last year.

Agree, the t type mech works fine with a regular 12 speed cassette, chain ring and chain. You might have to space the cassette away from the wheel a little, I didn't need to as the micro adjust in the mech was enough to put the mech in the right place.

I'm using my t type mech with a garbaruk 12 speed cassette (on a shimano microspline hub) , and sram gx Eagle chain,it all works fine. Maybe the shifting isn't quite a smooth a a full t type setup, but it's pretty good still.

hi microspline hub cassete(XT) works fine with t type shifter and mech?
I brake my derailleur hanger and I don't know whether to change to sram.

Ran into a rider with Sram gx transmission today that was walking out of the woods. He was complaining that somehow he kept having battery issues. I was stumped so when I got home I did a little research and found this video that explains his issues….. didn’t know where to post it so here it is.

That issue happens on the old (none t type) gx axs derailluer too, and that has a vertical battery, so it's nothing to do with the battery orientation, but it is definitely true that the pogo pins go bad and cause a poor connection.

Has anyone tried this, or something similar?

  • I have two bikes, one with GX T-type, the other with GX mechanical 12-spd.
  • I would like to be able to swap wheels between the two bikes (one is 27.5", the other 29")
  • Thinking I try the 2.5mm spacer behind the cassette on the mech GX wheel. It sounds like that will work with the Transmission, so the question is, will I be able to tune in the shifting on the mechanical GX bike, with the cassette moved outboard 2.5mm?
  • Both bikes have the same rotors and brakes- I used to swap wheels before upgrading one bike to T-type.

Hi! Curious if you had to add a spacer behind the cassette? I have the same Garbaruk one and was thinking about a T-Type derailleur.

Maybe I found a solution my ebike has a sticker right where the seal is i removed it.

In case anyone else was wondering- the T-Type cassette bottoms out against the UDH when installing the wheel with the GX mechnical drivetrain. I think I have read elsewhere that you can modify the UDH to make it work, but so far it looks like a no-go.

For anyone that’s interested, I finally got round to testing the GX T-Type mech with a Shimano 10/51 cassette and a Shimano 12 speed chain and T-Type Bosch 36 toothed chainring on a 2021 Trek Rail.

By following the exact same setup as the full T-Type system on the AXS app I can confirm that it does work, the only change I had to make was adjust the microshift down to down, after that all gears changed well, the only gripe I have is that the Shimano chain is quite noisy on the SRAM chainring so I "wouldn’t" recommend running it with the SRAM chainring and Shimano chain (edited to keep everyone happy)

Just to share that I'm also running a mixed setup and for me works seamless, probably in future I'll try the full AXS setup:
- Sram T-type GX
- Shimano 10-51 Cassette
- Shimano chain
- Praxis 34T chainring
- Bike Giant reign e+

I was previously running a t type gx derailleur with a garbaruk 12 speed microspline cassette and sram gx (none t type) chain, and it all worked perfectly without any modifications needed.

After about 2000 miles that cassette and chain was worn out, so I just replaced them with a shimano xt 10-51 Cassette and shimano xt chain, keeping the t type derailleur. And this also works fine, but this time I moved the jockey wheels on the derailuer in towards the back wheel by putting a half milimetre thick washer behind each jockey wheel. Again this setup seems to work perfectly. The derailuer micro adjust is on position 12 of 14.

Ill probably go for the proper t type cassette and chain at some point, but didn't want to spend 200 quid on the cassette, plus having to buy a new sram hub for the back wheel.

Late update here- using a belt sander, I removed about 2mm off the inside face of the UDH, to provide clearance for the chain, and reset the limit screws & cable tension. With these mods, the mechanical GX derailuer/shifter & chain shift great on a GX T-type cassette.

Next I put the original wheel with the mech GX cassette back on. I installed a 2.5mm spacer behind the cassette, to get the same chainline as the transmission. Basically full mech GX with a modified chainline. This worked well too, though oddly not as well as the mixed set-up. My take-away is that most of the shifting benefits come from the t-type cassete, so I'll probably run them on both wheels.

I need to replace my Eagle chain. It's a standard, non-transmission Eagle setup. Has anyone just slapped a transmission chain on the standard Eagle cassette?
My existing Eagle kit is all X01.

I understand the chain's rollers are slightly different diameters between Eagle and transmission. Anyone had any experience with this?

I've done some experimenting, mainly because I wanted to be able to swap my 27.5" wheel w/transmission cassette between my two bikes (one with transmission, the other with mechanical GX). The one combination I didn't really try was transmission chain on the mechanical cassette, so not sure I can be of any help to you. What I can say is that the 12psd mechanical shifter/derailleur work GREAT with the transmission cassette. Far better than with the mechanical cassette. This was testing with the non-transmission chain. I think most all of the improved shifting & ability to shift under load, comes from the t-type cassette.

To get the T-type cassette to work with a derailleur hanger, you have to take 2.5mm off the inside face of the UDH. This is not the surface the axle sits against, so nothing is compromised. It took 2 minutes with a belt sander.

I'm going to run this set up on my other bike (GX mechanical shifter/derailleur, transmission cassette & chain). Then wheel swaps will be no problem.

I've ran the transmission chain on both an e13 TQ chainring, and a SRAM transmission chainring. Both worked, but the SRAM chainring was much quieter.

Hey have the same bike/idea, did you have to use a freehub spacer behind the cassette or does it work without it? How is it going so far?

Hey If I understand correctly, you disassembled the cage and put a half mil washer on the outer side of each jockey wheel?

No spacers behind. Still working perfectly. Shift under load as well improved compared to Shimano shifter
Awesome, what is your micro adjust setting? I am currently running the eagle axs, but want to get a t-type as it shifts a bit slower and that's better for wear and longevity of components on an ebike.

Interesting, what was the reasoning for that, did you have shifting issues or?

A proper sram t type cassette is positioned slightly closer to the right hand side of the bike than a shimano xt cassette, so in order to make a t type derailleur work with a shimano cassette you either have to move the cassette to the right or the derailuer to the left. The washers effectively move the derailuer to the left.

This setup (with the washers and a shimano cassette) works great for me. Without the washers it didn't work at all.
