Cool! Do you know if they have any issues with it making the wheelchair wider and therefore causing problems with doors/turning? I guess I'd have to give up my 2 degree camber with those wheels but it might be worth it.

From what I can tell (having not used one properly myself), they fit the components within the push rim, so there's no real issues with doors or turning. Just done some research for you, and looks like they can actually support camber, too!

Thank you! Much appreciated. The last time I looked at these kind of wheels they were big enough to require some modifications to the chair itself - looks like even wheelchair technology gets a boost from time to time.
