Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Fixie in a trainer - quick release a bad idea?

I just got an Ascent magnetic trainer for the winter, one that wants me to use its quick release skewer. Anything special about skewers paired with trainers besides that they fit in the holds? My rear axle with track nuts seems to fit perfectly in it...I was on it for an hour this morning and it seemed to hold up.
I've also heard about how easily quick-releases can go loose from the chain tension on track bikes, which really just sounds like a terrible situation.

if you don't mind squishing the edges of the nuts a little...

You'll be fine using track bolts. It's just as solid with your track wheel as it is with a quick release wheel. Lots of people use those types of trainers. Just don't do any violent waving back and forth (not that I would expect you to)...but that would also apply to a quick release wheel.

IDK about the quick release supplied with your trainer, but mine came with an old fashioned closed cam type, that clamps the wheel very securely and it won't slip under a hard load. These were used in the old days on road bikes with horizontal dropouts where a wheel slipping out would be even more disastrous because it would fall out of the frame, so they are just as secure as track nuts.

Aw, crap! I was just about to throw my bike up on the ol' trainer and do all kinds of violent waving back and forth!

the supplied skewer is always the cheap enclosed type with steel ends, because the open type will just slide right out from the trainer's vices. the aluminum and plastic ends on good skewers will get marred or broken quite easily.

That's probably what it is actually. It reminded me of what came in my Peugeot before realizing how easily wheels get stolen. So they're strong enough to withstand all the tension / ****ty roadage my rear wheel will withstand? Can I whip my bike back and forth on my trainer with it?

I think i'm legit the only fixie rider who can't skid (I can lift my rear wheel up in motion, but that just looks silly and isn't effective) so maybe I should.

Some quick release cams on the trainers may jump loose and release the wheel. It happened to a guy I know. He was out of the saddle sprinting on the trainer and the trainer's cam came loose and released the wheel. Nothing catastrophic, but he put a hole in his disc as he fell over.

EDIT:

This would have happened if he used a quick release rear wheel, too.

This is why some trainers come with a screw system to bind the wheel, like this:

Skid on the trainer.

I can't even afford my own trainer, I'm borrowing it from my mother. but god, that thing looks beautiful. Looks too complicated to mount and unmount though (because chances are I'll leave my bike on it until the next morning when I'm rushing off to work)

Back then I was trying to get on a trainer with my solid axle hubs but soon gave up because I didn't want to risk ruining my track nuts so I invested in some rollers. However, I did come across some of these http://bike.com/tacx-track-wheel-ada...rs-and-rollers ... not sure if those would work with a different manufacturer.

If you are all that worried about hex nuts not fitting the cups of the trainer, how about taking a set and having the very end rounded over to fit the cup. Or, it can not be that hard to have a set machined.

I do not know if you can get extra long hex nuts that fit the axle threading or not, but those could be turned down so you can keep the same flat width for the wrench. And you could round them over using a drill and a angle grinder with a sanding disk.

My 1-ups trainer even though it cams into the rear axle to close it, has adjustable cups for the width of the wheel axle.
