Review on Topeak Presta Valve Extender by Anferny Pineda

I switched to a set of 35mm carbon wheels and Tubolito tubes but didn't want an ultra light tube so it only came with a short stem . Other adapters required removable valve stems to work. it works, which is not possible on Tubolitos. This was my last chance and I was a little nervous about the mediocre reviews. They arrived, screwed in easily and worked as promised when using light pressure unscrewing and reinstalling the Presta valve stem. Once they loosened on me (no bleeding) I tightened them and no problem since. Try it, they solved my problem
