Fluff question of the day - use valve stem caps on Presta?
Is there any need to put a valve stem cap on a Presta valve?

Cap and nut, pitch them both. Not a weight savings issue to me, to be they are just two more things to have to remove when I'm on the side of the road changing a flat with sweaty hands.

You Know!? For Kids!
yes, of course, but run carbon fibre ones to save weight and make sure they are gram matched to keep wheels in balance. Nothing worse than having your valve come unscrewed spontaneously and then have some sort of abberation in the laws of the universe occur that allows the presta valve to open against the force of the air in the tube and you get instant deflation. Happens to me all the time

On my roadster, no valve caps or stem nuts.
But on my mountain bike, I have some chi chi red anodized aluminum valve caps for the pure pimpin' bling of it.

Why not use the nut? It seems to make it easier to put the pump on if the valve is immobilized against the rim.

The nuts stay on mine. Nothing drives me crazier than noises on my bike, and without the nut, the stem tends to rattle around in the hole. No thanks.
I also keep the caps on. I color coordinate my caps with my cable housing. It's a OCP thing.

The cap is for transporting the tube in the box to keep the stem from poking a hole in the tube. If the valve is closed there's no place for dust to get in.

Sometimes I forget to look where the stem is when I grab the rim.

My mech at the LBS always rolls his eyes as he says, "Oh yeah, you're one of those nut and cap guys" as he puts them back on. Yesterday he left them off again and I said nothing.
This morning, with some trepidation, I rode for an hour and a half with no caps and only two nuts (neither of which were bike parts). Nothing untoward happened. No noises. No valve failures. Nothing.
Well there is one thing. I did notice my average speed went way up.
I'll probably leave them off.

I spin the wheel slowly, if it stops with the valve at the top then I add the cap and/or the nut, if it stops with the valve at the bottom then I leave it (them) off. No AR's in my family.

How do you get the nut off? Mine stops when it's fully unscrewed. Do you Dremel it? Besides, it seems a little too easy to bump the stem and deflate your tire a little without the nut.
