I run Vittoria tubes on my race wheels and they are not threaded for a jam nut. I use a crack pipe to inflate both tubes and have never been able to properly seat a pump head using threads. So... I end up holding (pressing) the crack pipe up into the valve stem to get a seal and pumping by sitting onto my pump handle. It's not difficult to do but I keep bursting latex tubes because the pressure I'm putting on the valve stem weakens the tube (it's super fragile in the area believe me).
Anyone have any suggestions? I've lost probably 5 tubes in the last few years.
