I have a NEO 2T mated to a 2006 Specialized Roubaix that has a 9 speed cassette. Based on Tacx videos posted online and feedback from my LBS, I used two thin spacers to help ensure that the cassette is installed properly and doesn't slip. I noticed, however, that the stay on the non-chain side rests against the trainer case (see image). This doesn't appear to affect the functioning of the trainer, but I can see where it's rubbing against the case.
Is this normal; or is there are there's I should make to this setup to mitigate the issue?
thanks,
Randy
