I bought a used trainer and it came with a trainer skewer. I don't know if it's the original from the trainer.

I've put in the trainer skewer and have mounted my bike to the trainer. However, I noticed that the skewer ends don't go all the way into the cup at the mounting points. It's most noticeable on the side with the quick release.

You'll notice that the cup even has cut outs on both sides for the quick release lever, but the qr stem end is only half way in.

Should I be concerned? I've done a couple of training sessions and the bike was totally stable.

  • Does the head of the QR go into the cup all the way if the QR is not fitted to the bike? Does it touch the bottom of the cup?

  • I suspect that QR is not the right one for that trainer.

  • When he skewer is not in the bike the wrong end does not fit into the cup.

    I wonder if you were given the wrong skewer. Jun 17, 2020 at 12:24

    @DanK : you’re right that it’s a Tacx skewer. My trainer is from Kinetic. I guess the Tacx skewer just doesn’t fit.

I bought a new skewer for my trainer...the one the manufacturer sells. The two ends fit nicely into the cup.

qr skewer skewer other end with washers

You’ll notice that I had to stack 3 washers in the other end. The skewer was poking out the other end too much and the cup would not seat all the way in.

washers for spacing

  • Will the washers be okay? Doesn’t seem like it will be an issue.
