aero tubes and cores, what to do?KurtVF
Sep 1, 2002 6:50 PM
I have aero rims, I'd like to be able to use regular length stem tubes (cheaper, more variety, more available)with extenders. Most of the extenders(Vittoria, Campy)I've seen need to be used with stems with removeable cores. How do I know which tubes have removable cores? Or is it just easier to buy the tubes with long stems?????

Valve adapters are an endless source of aggravation and annoyance. The ones that you use with a removable valve core are better than the other style, but they're still a nuisance. It was one of the greatest days of my life, years ago, when I first discovered a Torelli tube with a long stem. I've never used a valve adapter with that set of wheels (Shamals) again. However, I now have a set of Zipp sewups for race wheels, and long valve sewup tires are few are far between. So I'm back to dealing with adapters again. But if you're riding clinchers, don't even think about adapters. Just buy long stem tubes, and be glad they're so easy to find!

I have had problems with the valve not seating correctly and leaking when the core is down in the tube since you can't screw it tight. Also, the valve core can vibrate and screw itself tight and then you can't fill the tire. Extenders are a pain - but a necessary pain for deep rim wheels.
