I switched to 11 speed on my road bike recently. I just went to put an 11s cassette on my trainer wheel and discovered that the freehub won't take an 11s cassette.


The wheel is only ever used on the trainer. Should I:

- Pull a cog off the 11s cassette, which will definitely work

or

- Leave the 10s cassette on there and hope for the best


? In either case I will need to be careful not to shift off the end of the cassette while on the trainer.
