Do you guys have any problems switching between wheel sizes? I have a a 26 dh bike and trail bike at the moment, and am toying with the idea of adding a dope-ass-swagtastical 27.5 trail bike to the stable. My trail bike sees alot more use than the dh bike. If I pick up a 27.5 trail bike, should I expect some "re calibration" in my riding when switching between the two wheel sizes?
