Hi all, hoping you can help. For three months I used a Tacx Flux wheel-on with zero problems. I then ‘upgraded’ to a Kickr Core. I have always had a horrible grinding noise and feeling when in the highest gear on my 8-speed mountain bike. I took the bike and trainer in (a ballache) to a local reputable bike shop, who says that they adjusted the deraiileur and made some tweaks and that it was all working ‘perfectly’. They charged me £15 there was that little to do. I’ve just got it all back and the highest gear is doing exactly the same thing. I’m absolutely dispairing and thinking of cutting my losses and selling the Kickr and going back to the Flux. Does anybody know what might be going on here? Could it be me ‘seating’ the bike on the trainer wrong or something? I’ve used the exact same adapter configuration as the shop… Thanks.
