Turbo undoing lockring

[chadwickwilliamso]

Hi, on both an 11-speed quick release bike-and-set-up and a 9-speed quick release bike-and-set-up my Suito is unlocking the lockrings so that the cassette comes apart (regardless of how tight I fasten the lockring. What am I doing wrong? Thanks!

did you add the spacers on the freewheel before install the cassette?

Thanks for reply. No spacers for 11-speed, 2 for 9-speed. It seems the lockring is jamming against the inside of the frame and that’s what is undoing it…

did you try to screw-in the locknut without the cassette installed? you have not to tight it, only to see if it screw-in correctly

Thanks again for your reply - the locknut screws in correctly. The issue is that when I start to use the turbo there is too much friction between the locknut and the frame of the bike - this means that the pedals won’t turn smoothly and eventually the locknut comes undone.

If I loosen the quick release sufficiently then it does work but this compromises the stability of the turbo.

can you please post a photo?

it's strange that the cassette touch the frame, it's a specialized SCS? it has a different distance of the hub, if i remember correctly, it doesn't fit with the trainer
