I was on the turbo last friday when I heard a cracking sound. Bike is ok. I looked at the skewer that comes with my Tacx trainer. I know this maybe difficult to describe but I'll try.... The skewer end with the lever seems wobbly.....and Im not sure if it should be. When I go to undo or tighten the skewer I notice that the lever end wobbles. This maybe fine.....but Im reluctant to use my turbo just incase it isnt and that I need to buy another one. Can you check your TT skewers and let me know. Cheers all.
