  • My bike has an 11sp shimano drivetrain, but my turbo wheel has a 10sp shimano freehub and cassette.

    What is the simplest and cheapest solution to get them to play nicely together?

    Simplest full-function method is a Marchisio cassette, with 10 sprockets at 11-speed spacing. Quite expensive though, so it might be cheaper to rebuild the wheel with a 5800 hub and cassette. If your turbo has easy resistance adjustment, the ghetto method is just run it as a two-speed by leaving the chain on the top sprocket and front-shifting for gross adjustment.

    I think this may be the interim solution.

    Problem is I have 1 turbo wheel and multiple bikes with different gearing, so sometimes I want 11sp spacingand sometimes 10sp spacing.

    Longer term best solution is probably to swap the hub and then either use 10sp with spacer or 11sp.

    @hippy 99% sure it's 10sp on the turbo wheel... It's an old ultegra hub and probably predates the invention of 11sp. Cheap turbo wheel is cheaper than ruining expensive tyres on the turbo.
