SRAM AXS - b tension screw keeps winding out

[James_C]

I have SRAM AXS Eagle on a 2024 kenevo. The B tension screw keeps winding out every few rides. Not just a bit, all the way out, the jockey wheels hit the cassette! I took it out, cleaned it with a wire brush and made everything clean, blue loctited it, and adjusted it and put a dot of superglue on the mech/screw as well. Its now adjusted out again.

How do you keep these screws still...???

Don't they have a small black plastic block somewhere that acts like a nyloc?

Blue Loctite as in Loctite 243? That’s designed for larger and higher torque bolts really, so perhaps try some Loctite 222 (purple) which is designed for smaller bolts and lower torque applications?

If that doesn’t work, then a bit of Loctite 290 wicked down into the screw after you’ve set it where it needs to be will keep it there, but it may require heat to loosen it again.

To be honest, all my screws have always stayed where they should, I wonder if your mech has an oversize thread that means there’s too little friction, or the screw is undersized?
