Trainer skewer vs road skewer?

I dont really have a "Trainer Skewer" but I do have a couple old ones from the back of the garage that will fit in the trainer.  The new ones dont seem to fit.  So I use the old on on the trainer and the new one on the road.  As to why I don't just use the old one for both?  Well the old one is silver and the new one is black.  I can't go riding around with the wrong color skewer!  That and the new one is a little lighter than the old one.  Clearly that will make me faster!!

To preserve the aesthetic of the racing machine.

The trainer skewer is a bit heavier.....so if you are a weight weenie then this is a concern.

I generally leave the trainer skewer in until the "ify" spring season is over and then switch when I know 100% of my rides will be outside.

The skewer that comes with the trainer is what used to come in road bikes years ago. New skewers are now lighter. Nothing wrong with using your trainer skewer unless you want to cut down weight.

I keep my trainer skewer in until I know I will not be using my trainer b/c I'm outdoors for all my rides and then put my lighter one in

Your road skewer may not fit in your trainer. You don't HAVE to have an actual "trainer" skewer--just one that fits in the cups. We've got a box full of skewers at home, and whenever I put a bike on the trainer, I just find one that fits.

FWIW, I never take it off. My tri bike always has one on the rear wheel.

Doh! >.<

Roland, you live in Southern California....all your rides should be outdoors! 

Yes, yes... I know... I ummm, do my long rides outdoors on Saturdays.  Yeah!
