• I'm thinking of getting the Wolftooth roadlink and want to try and keep Shimano cassette and my short cage di2 RD. I have DT Swiss rear hub that didn't fit 11spd MTB cassette for some reason. I think the MTB cassette in 11spd is skinnier or wider?

  • There is an 11-34 11 speed Mtb cassette that will work with 10spd hubs, and the new medium cage ultegra rear mech can work with it too.

  • I think Shimano do a 36T and 40T MTB cassettes too but I have 11spd DT Swiss hub and I don't think they fit for some reason - too skinny or too wide?

    What is stopping me building a new wheel with Shimano MTB hub for 11spd road use? Is there some spacing or disc rotor issue?
