reduced 11 speed cassette on 10 speed hub

Hi, advice wanted on this subject.
I have almost new Easton sl90 wheels which only take 10 speed, and the freehhub doesnt seem to be replaceable.
I am wanting to go up to Di2, which nowadays is only 11 speed, but I resent the waste of wheel, so have come up with the following "cunning plan", but am not sure it will work, so advice welcome!
Can I use an 11 speed cassette with one of the sets of teeth (ie, the 11 sprocket) missing?
In particular, A) will the cassette fit securely?
B) will the mech have the right intervals?
C) can you use limit screws on Di2 to stop after 10?
thanks in advance for comments

  • The last sprocket of the cassette needs to have the teeth to engage with the locking. As long as the locking can be tightened and put compression force on the cassette, you are up to a winner. I think it's the most economical solution... the low end of the cassette is pretty useless anyway...

    One thing you'll need to be careful with. If you accidently shift into the 11th position it cannot go into because of the limit stop. It may damage the derailleur motor.

    Thanks, interesting thread.....
    Presumably if one did make the mistake of trying to beyond the smallest cassette, you'd have a few seconds to realise your error before damaging the motor?

    Anyone esle using a 10 speed cassette & 11 speed shifters?
    Or would this only work with dura ace?

  • I use an 11spd shifter/mech/cassette combo on some 10 speed winter wheels.
    I removed the 16, put the spare spacer to the back next to the freehub and stopped the mech off accordingly.
    Works perfectly.

    I'm using this product with Ultegra Di2 11s on old Dura Ace wheel.
    It works perfectly.

    Last gen 11 speed cassettes fit into ten speed hubs. I have one on my carbon tubular 10 speed 60s and also on my 10 speed 58mm Supra wheels.

    Just try it and see.

    Presumably this is only true of wide-range cassettes, where the large cog will leave enough standoff space for the derailleur to clear the spokes?

    12-23 or 12-25 on both. One of the two.

    Just bolted them on and set up the mech.

    The Supras with an 11 cassette also work fine with Ultegra di2 on an S5.
