road tube with a 2 inch long valve...

Last year I bought a few 700x19-26C road bicycle tubes from Performance Bike,
the ones I always buy, and today when I opened them the first time I was
shocked to see that they all have 2 inch [5 cm] long valves. In the past all
the tubes I saw had 1.25 inch valves.

Is this normal? Could they be simply mispackaged? Can I use them on a normal
tire? Any suggestions?

I know I could send them back for replacement but it's a lots of extra work
which I'd like to avoid unless it's necessary.

Thanks, Paul

Those are needed for some aero rims, and other than the slightly
greater weight, they work just fine in rims that can use a shorter
valve. If you know somebody who has aero rims, offer to trade.

Odd, that's the size I prefer, and I can't get them at my local Performance.

They will work fine, they just look funny. Careful when you inflate, it's
easier to bend the stem and give your self a flat.

My local Performance only carries only two sizes, but I find 3 lengths of
Presta stems in local shops:
1) Regular (approx 1.25 inches)
2) 48mm (probably what you have)
3) 68mm/Long (Super long, way to long even for my Velocity Deep V rims)

OK guys. I appreciate your advice. All of you told me that it's OK to use it
so I will. Many thanks, Paul

Be careful when you pump up long stems in normal box rims. A sloppy pumping
technique can cause the stem to be tilted in the rim hole, which can cause
damage to your tube.

OTOH, with Prestas, I find the extra length gives me something to grab
so that I can stabilize the stem while I'm hooking up the air hose.
Of course, if all you have is a hoseless pump, then your caution
warning is very appropriate.

Good advice even with "hosed" pumps. Best regards, Paul

'Normal' lengths are 36mm, 48mm and 60mm.
