90 degree valve stem.

What is the proper mounting direction for them?

Most pictures I see it is mounted with the stem facing the brake disc on the rear...like this.


Is that proper? or should the stem be facing in line with the wheel instead of "crossing" the wheel? (though that would kinda defeat the purpose of the stem?)

FYI these are the stems I have: Kurvey Girl stems


Thanks in advance

Since you use your bike on the street, I'd mount it facing the rotor. That way you can fill the tires with the bike on the side stand.

All my euro bikes had angled valve stems, and they were all pointed opposite side of the kickstand for easy tire checks.

Get the 45 degree ones next time. Some of the 90 degree ones aren't as long enough to allow you to get the bare air hose on them to bead new tires. If you're OCD about your bike, the 45 keeps the quick release part of the air chuck away from the paint and less likely to scratch them.

90 degree ones don't really work all that well. Get the 60 degree ones, or the 45 in the future. Some air chucks can't fit on the 90s because they are too close to the rim.

I can show you a variety of them next time you are over.

Kurveys arent exactly 90's.


I'm sick of following my dreams. I'm just going to ask them where they're goin', and hook up with them later!!

Angled valve stems

Mounting them pointed towards the disc facilitates filling when the bike is leaned on the kickstand (nozzle away from chain or grease). Mounting them parallel to the rim rotation is NFG.

Angled Schrader Valves FTW!

All done. pointing away from the kickstand. I had no issues getting the hose on for setting the bead.

Thanks for all the input.

We used the 90's on all of our front wheels....keeps you from burning the top of the hand on the rotors...the 45 and 60's are nice as well.

I've got some if anyone else needs any...
