I am using an old but great bike on my current Wahoo Kickr Snap wheel-on trainer that is 7-speed. I’d like to upgrade to a Direct Drive trainer, but the 7-speed cassette does not naturally fit.
I’ve read the threads I could find on the forum regarding 7-speed cassettes on a Direct Drive trainer and watched the video of the individual simply putting in spacers and filing one down for rivet spacing. OK, so theoretically it works.
I’m curious if we have any Zwifters that are actually running a 7-speed on a Direct Drive trainer and how it is working for them. Does the cassette positioning with the spacer leave it in a place that works for the derailleur and it shifts well? Are you happy with the end result and your ride on the Direct Drive? I’m thinking of the Wahoo Kickr Core or Kickr though would be open to other units if one works really well with a 7-speed.
Thanks for any insights folks have
