I have a hybrid bike that I am desperately trying to setup properly on a Tacx Neo 2t. The bike is 7-speed, the chain, the cassette, the derailleur - all 7-speed. I know that tacx says the unit is compatiable for 9, 10 and 11 speed. I don’t have this kind of bike.I bought a Shimano Ultegra R8000 11 Speed Cassette with my Neo because I thought this might work.
And it did. For a while, the 7 speed bike worked with the 11 speed cassette. Of course, some gears felt weird but i could actually use the trainer. Then, I tried climbing something for a long time. It was loud but the bike had just detached from the freehub. So i just fixed it on again but the chain since this ordeal keeps on slipping and sliding. The chain is holding onto the casette very poorly and keeps slipping. There’s no way i can use this trainer like this.
What are my options? Is this beyond help?
Grateful for all advice.
