The lightest tubes I`ve had, after taking my old tubes out and comparing them to these badboys the difference is huge, quality product and merlin provide very fast service
This is Lightest tube with very good quality
SUperlight tube, about half the weight and size of a normal tube. I'm sure they'll be more prone to punctures, but great for a light set of wheels, of as a compact light weight spare.
