Review on Schwalbe SV7 Tube Presta 1 5 2 50 by Marfel Fekete

These are the lights that I think suit my TerraTrike best. They are not that common and definitely more expensive. But they are the right size (other manufacturers tend to be narrower and "split" or "pinpoint leaks" after replacement. My only "negative issue" is the higher cost. And that's probably due to the back- and return shipping is no "local" source for such things (and I've also worked in the international shipping industry).
