Roly Wheel and Gabber Rex

[Bailey-Benji]

I bought Bailey a new large roly wheel last night and I attached it to the bit of the gabber rex where the wheels go.

However, I watched her try to run on it and the back of the wheel is hitting the side of the ramp of the Gabber Rex which makes it hard to spin so it's a bit of a struggle for her.

I ended up putting her habitrail wheel back in.

Any ideas? Has anyone else got a Rex and a Roly?

It fits perfectly, but its just not turning well.

Thanks :)

All ours are attached and they do sometimes bump on the back but if you smear a bit of vaseline, just a touch on it it helps it run more freely. Ours never have any trouble moving them though. Maybe our hammies are light!!
