I use those light ones on my Swift and only have good words for them. They are really so much better in air retention - with cheapies I would pump once a week; with Schwalbe, months go by between pumps. Literally. Mostly I only pump when repairing a puncture! I only use Schwalbe on all my bikes.

Worth the money, and I patch these many times over before thinking about chucking them in the bin. In fact I have yet to throw one away.
