That's where I bought one group. Totally legit and fast delivery (signature required), but limited units available.

For those who missed my last update, the standard RD only needs a 25mm long B screw to use a 10-36 cassette. There is no short and medium cage. All are 70mm.

what you mean?
Force now has a medium cage RD that supports a 36T cassette. That said not surprise the short cage one does as well.

I said that there is no medium cage. I have one and it measures exactly the same 70mm as a short cage. The difference is in the length of the B screw. A 5mm longer screw insures adequate clearance with a 36 tooth sprocket. I bought an M4 button head screw, 25mm in length for 85 cents, ground the head down to a smaller diameter, and replaced the 20mm B screw. Both models have the same 39T wrap capacity, but I run a 42T combination with it.

I bought a "medium cage" model, just in case I needed it. I will be returning it because I don't need it, since it's NOT a medium cage. It does have 36T written on it.

interesting... thats good to know.

What?? Non disc and 2by?? Is that even legal??

Dave, is there anyway you can take side by side photos comparing the 2 derailleurs? Maybe a video with you shifting through a 10-36 cassette with the standard Force AXS derailleur?

No point in that. I measured both the cage length and parallelogram pivot points. All were the same. All they did was install a longer B screw and mark 36T on it. I sent it back, unused, to get a complete refund.

Now I have my second bike running with axs 12 and an 11-34 Campy cassette.

What's the advantage of this vs a SRAM 10-33 cassette? Merely because you had it already?

Exactly. It also proves the either SRAM or Campy 12 shifting systems can use either brand of cassette. The 11-34 also has much better spacing of the sprockets, IMO. It has more 1T jumps and larger jumps in the big sprockets.

I noted earlier, that there's a chance than Campy will have a 10-36 cassette sometime in the future. If they do, it would be based on the 9-36 13 speed cassette, without the 9. It would have a 14T sprocket, that I would like to have. It will also require their new freehub body.

I have a moderate descent down from Estes Park to Loveland. It's common to be riding in the 25-29 mph range, right where the 14T would be nice to have, rather than a 13-15 jump.

As I mentioned earlier, I'm about to assemble a Campy 12s mech group, 48/32 and run AXS 10-33 in the rear for the small gains at the high and low end of the range. I've not fully abandoned the idea of C12 11-34 though.

One consideration is system efficiency and think I recall reading someplace that 9 and 10 tooth cogs create more drag on the system than 11 or 12 (or larger). Am I imagining this or has this been addressed?

If you're at the point where you can turn a 48x10, drivetrain drag is not an issue to worry about.

[Dave]

A 48/10 is the same as a traditional 53/11. I use it soft pedaling down some descents or as part of a brief run up to 50-54 on a steep downhill. With a 48/10 I pedal up to 42. With a 48/11, I quit pedaling at 38 and coast on up to 50.

Were you able to confirm with Easton that their chainrings works with a 12 speed chain? I can't seem to find information on this anywhere.

No answers from companies regarding compatibility, just reports of of other riders doing the same. I’m actually using Praxis rings though.

From Campy to SRAM? What’s happening to humanity?

Bumping this old thread to correct my comments about the SRAM AXS 36T capacity RD and remind myself when I started using SRAM AXS, almost 3 years ago.

The difference with the 36T capacity RD is in what most call the B knuckle. The derailleur sits a little further back than the 33T model. The cage lengths are the same. I'm still using the two 33T models that I bought back then, with two early model 10-36 cassettes. These don't every even need a longer B screw. They have enough wrap capacity for 16T difference at the crank, plus 26 at the cassette.

I've also got one 36T model in use.

There's still the same type of partial force group in hydraulic, now being sold for around $900, but few are left.
