My new zwift hub just arrived with a 12 speed cassette pre installed. The cassette is flush with the quick release adapter and it’s impossible to get a wrench on the flats to remove the quick release adapter.
Hi Paul, thanks for the suggestion. I tried that last night, I think the quick release adapter prevents it from coming out. 2 people, one one the chain whip one on the cassette tool couldn’t get the cassette to budge. So it’s that or the factory way over torqued it.
My guess is it’s just super tight. If you can get the lockring tool on the lockring, nothing related to the axle should stop the lockring from unscrewing.
I think the adapters are not screwed in, they just slip on. So possibly if you pull the adapter off the non-drive side, you might be able to use a skewer or anything you can fit through there to push the other adapter off…? (I’m guessing here - haven’t done it.)
Your other option is to take it to a bike shop to remove the cassette so you can get at the QR adapter.
It would be very difficult to damage the trainer by removing the cassette.
A user on Facebook reported that their bike shop said the cassette lockring was over-torqued. That would explain why some users have had such a hard time removing the cassette in order to get at the QR adapter.
I had the same problem. Very frustrating. I used a pliers to grab onto the small round knob that protruded out. I was able to loosen and get it out. Scratched and gouged the adapter, but I don’t need it (and probably would still work if I did need it).
