It looks like the only way to get a bigger tire in there is to either remove the brakes or add a link to the chain. I've got GSport Birdcages and EVOII brakes with the wheel slammed, and everything is kinda maxed out. The hoops are narrow, so I already had to move spacers in between the pads and the arms just to get them to contact the rims because otherwise the arms knock against each other before there is rim contact.
I think the best way for this problem to resolve is for Odsy to release a 2.1 version of the tire I want, but we all know that isn't going to happen.
