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.
One option would be to remove the cassette. You’ll need a Shimano compatible lockring tool and a chain whip. I don’t have that trainer so I’m not sure if there’s an easier way.
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.)
I was able to get it by grabbing the small end sticking out as hard as I could with a wrench and that did the trick. Damaged the adapter a bit but I didn’t need it.
