Any?

And do you think my FSA Energy crankset with TA 36/48 11-speed rings would work, assuming I don't use the Wide version electronic FD?

Thanks.

I've used a chorus 48/32 12 speed and a cheap shimano grx 46/30 11 speed with the chainline corrected to normal road bike. No setup problems or chain drops.

I'm running an Easton EC90sl with Praxis rings. I've had good luck but you have to use brand new rings IMO for best experience. I'll probably swap to Carbon-Ti over winter.

Im curious of those using non Sram AXS 2x Chainrings with Sram AXS Front Derailleur if you are having the same shifting issues (chaindrop) as others have had..

I ditched teh Sram AXS 2x for 1x because I couldnt get the chain to not drop.. I suspect this is becasue the Sram Chainring, chain ramps suck and dont move the chain, so you need to adgust the FD high/low to much then it throws the chain.

My LBS is amazing and got mine working perfectly. Used a Praxis 52/36 without a single issue and the. Swapped to a 48/36 (unmatched) set and after they worked their magic it's been flawless. I tried to set it up myself without a lot of luck but whatever they did worked great.

Thats great to hear... I am starting to suspect that the FD Sram AXS shifting issues is more caused by the ramps on the Sram CR than the actual FD itself.

The FD does one job, move the chain side to side within limits and the CR is supposed to catch and drag up the chain. So when adjusted within limits the chain just dances in the middle causing the FD to be adjusted slightly more outside throw. Then you start getting random chain drops.

So if Praxis, Easton or Rotor have a better CR ramp design this maybe the cure to crappy Sram FD shifting. Now all i neednis someone to make aftermarket sram AxS 2x chainrings :)

That disappointing, I was considering swapping over to a sram crank and rings in hopes of more unity but admittedly this was before the shop was able to get it set up.

No chain drops with Campy 12 or Shimano grx cranks. No problems with setup either.

For reference I went to my an LBS that deals in more boutique brand bikes and specialize in road racin etc.. The owner/ mechanic said he wouldn't touch my bike lol. He said he will not work on Sram 2x. He only sells and works on Shimano and Sram 1x.

Kind of crazy, he said the tolerances are so ridiculously small that even if he gets it to work he doesn't feel comfortable guaranteeing his work as the Sram FD easily gets knocekd out of alignment causing the same issues to arise

What a shame

Shim washers and longer chain ring bolts in the 10-12mm range will eliminate the +2.5mm chainline.

I used McMaster-Carr number 98370A015.

Isn't chainline of grx better for disc brake bike anyway?
Normal chainline is for 130OLD quick release wheels.
Disc push rear spacing to 135mm, so 2.5mm offset on the chainring make it correct again.
