Lance - now working as a shop wrench

Discarding the valve cap--is that a weight weenie thing? I never bother with it because , ahem, I'm kinda lazy that way, but every time the bike comes back from the shop the valve caps have been replaced with shiny new ones.

Valve caps are an important part of air retention in a Schrader valve. Those should always be in place and in good condition.

On a Presta valve, they're kinda pointless. A waste of time IMO, rather than a waste of weight. Mainly they keep the valve stem from poking through the wall of a new tube in the box or in the seat bag. I suppose they might give the stem a tiny bit of protection on 'cross bikes, but for the most part, skinny Presta tubes don't get ridden through the kind of debris that might threaten a valve stem anyway.

I think tossing the nut is kind of a weight weenie thing though. To me, they're useful for positioning a new tube, and at that point it's a waste of time to take it off again.

Makes sense. I will probably continue not bothering with the cap on my presta vlaves, even though I endure a lot of ribbing from a riding buddy who always notices that right off the bat. Now I can say, "lance says it's best!".
