• No, it won't shift properly because the sprocket spacing is different. You could butcher an 11-speed cassette to fit on a 10-speed wheel by omitting one of the sprockets and spacers, e.g. CS-5800 lends itself to that. Would probably need the 10-speed spacer behind the cassette to get the lock-ring to work. Or save yourself the trouble by getting a Shimano RS010 rear wheel, they're under £50 new if you shop around.
