I recently bought a cyclops trainer. It is annoying to switch the skewers. I know the steel skewer that came with the trainer is heavier and stronger, but I don't know if it will damage my bicycle off of the trainer.

I do know that riding on the trainer with my normal skewer will wreck the normal ones.

Do you mean the quick release skewer that runs through the centre of the rear axle on your bike? – Мסž Apr 11 '11 at 2:50
yes, I mean the quick release skewer. – Dale Apr 11 '11 at 19:49

I assume you mean the quick release skewer and the answer is no, well at least not in my experience. I've spent a few years riding on the training skewer from my Tacx trainer and had no issues outside of the visual detraction of a silver skewer on black rims/wheels.

No, using a "trainer" skewer on the road has no negative impact on your bike or safety. The skewer which comes with a trainer is mecahnically and functionally identical to the one that came on your bike, with the exception of the shape of the "heads" on the trainer skewer. It is actually identical to one of the original skewer designs. The reason that one comes with the trainer is because most bike manufacturers have changed the shape of the skewer "heads" that come on the bike to be more aesthetically pleasing. With the side effect that the skewer that comes on your bike is unlikely to fit securely into the clamp mount on your trainer.

I have ridden several thousand km on the road with my trainer's steel skewer, QR and nut in use on an aluminum frame with no problems at all.

For training the weight just doesn't matter...realistically this is an aesthetic choice. There was a time when all these parts would have been steel.

Note if you ride in the rain your steel bits may corrode.
