I currently have a pair of presta valve extenders that work with removable core tubes. These work great and I've had zero problems with them. I have no idea what brand they are as they came with my 58mm November wheelset.

However. As I found out Wednesday. When your spare tube flats, you need to rely on the generosity of others. Luckily I have a very generous group of people I ride with. They all gladly shoved their tubes my way but not a single one had a tube with a removable core that I could use in my wheels.

So..... I want to buy a couple valve extenders that work on tubes without removable cores. I will still continue to carry my own spare tube, but having an extender that will work with a donated tube would have prevented me calling my wife to pick me up on Wednesday.

There are a million out there but I have no idea which ones work the best. My LBS is ordering a few for me, but I wanted to know what he community has used so I know which ones to buy. Thanks

Zipp extenders are perfect... but you know, you'd be better off not using extenders except as a backup situation. Get a box of 80mm valvestem tubes (Conti and Bontrager make them).

I have the Topeak valve extender and it works very well. I carry it strictly for the same purpose you do, as a back up in case i need to use a friends tube. I carry an 80mm valve spare tube but if the tube fails for whatever reason hopefully i can bum a tube off a friend and use the extender.

I use the Zipps for non-removable cores. My tubulars are removable core Vittorias so I use their extenders. GL

One thing to keep in mind about the zipp extenders is they need teflon tape to seal fully and you need an allen wrench and small plier to put them on properly. I think for an emergency extender, something like the topeak with a built-in rubber seal might be better.
