I have an old Shimano WH-R550 wheel I use on the trainer. It currently has a 10speed freehub body to match my road bike, but my TT bike, which I intend to use on the trainer over winter, is 11 speed. Rather than source a fresh wheel, I’m hoping to just get a new 11 speed freehub body. Can anybody s…

I don’t think you can do it with Shimano wheels. This site tells you how you can make a 10-speed cassette with 11-speed spacing. Dark Speed Works - Use 9/10speed Wheels With 11 speed Dark Speed Works - Use 9/10speed Wheels With 11 speed The custom-machined …

Ah, that’s a pain but I’m not surprised they’re not compatible :sob: Going to buy a smart trainer soon, was just hoping a 30 quid freehub body would tide me over for a wee while.

That only works the other way round (10spd cassette on 11spd body w/ spacer), this hub is definitely 10 speed, tried to put the 11spd hub on but there’s not enough room for the 11t ring to engage on the splines.
