I too have a cyclocross bike(gt zrx)with avid 1.0 canti's,the only time I need to pull the wheel out is when I have a flat,with there being no air in the tyre it comes straight out ,and then on putting it back I inflate it once it's in position again ,as I have the brake block/rim clearance set very close this is the only way I can do it quickly...keep the canti's they rock esp..with the koolstop red/grey thin line pads no squeel,just awesome power and modulation on the front brake.!!! cheers Buddy.
