Hi,
Rear wheel in my new wheelset is assymetric. I found that nut on Presta valve looks let say "stupid".
Is it neccessary to use that part? I do not have problem with pumping up tire without nut. To stop "rattling" I want to use heat shrink.
What do you think? Is there any reason that I should use it?

Speaking of nuts, has anyone else noticed that it's a mast year for acorns?

So, you're on the side of the road and just changed a flat.
As a purist, you don't use a CO2 inflator; you've sentenced yourself to this little 8" wanna-be pump that rides in your jersey pocket and requires 1,832 strokes to put air in a 700x23 so the velominati dudes don't snicker at you when they fly by on the A-ride at 26mph.
And you finally got that damned clincher tire's wire over the rim without pinch-flatting the third tube or breaking the unbreakable blue plastic tire lever because you had to use four levers and stand on the last one or cracking the carbon wheel you bought from your dental hygienist.
So you wiggle and jiggle and twist and wobble and try to get the damn head of the baby pump onto the valve stem far enough to seal but it keeps psssffting all the air out the sides and nothing goes into the damn tube which still might have a new hole in it cause you didn't rub a friggin cotton ball all over the inside of the kevlar chili dark matter advanced composition tire. Mainly, because you keep pushing the valve stem down into the 70mm carbon fakie aero shell of a wheel and it disappears down the damn hole and the air is going pssssfttt pssftfttft out the side and suddenly....
Oh... that's what those little nuts are for. I just chucked over in the grass somewhere....

I run Vittoria and Challenge latex tubes (likely made at the same factory) and neither have threads for a valve nut.

Agree so I get the michelins. That said, I bought a tube once but can't recall the brand, and it seems an obvious solution, and not sure why it isn't more universal, but why don't even the threaded valve makers just put the thread only at eg. the bottom 1cm of the valve and leave the rest smooth?

I put as many nuts as I can on my valve stems. Retro-reflective nuts made out of reflective dork disks, spoke reflectors, and valve caps.

This is not possible, unless the threads at the lower end are made larger in diameter, so the nut would slide over the unthreaded portion. Then the threaded portion wouldn't fit through the small hole in the rim. The smooth and threaded versions are both about the same diameter, so they fit the rim and presta inflators.

2) 26 mph? Is it a recovery ride for arthritic grandmothers? Real velominati dudes (Use the V!) don't even shift out of the little ring til 45 kmh.
Sheesh... Internet Freds...
