Nice-looking super-light inner tube. Easy to fit. Quite pricey but seems to be well worth it. Seems to be easy to stick with special stickers. Fortunately no experience yet. Nice looking and actually a shame to hide it in the outer tyre.
Initial fitting was good to do but a little trickier than regular butyl. Rides just as comfortable as latex only you don't have to re-pump every day. Unfortunately after
Punctured on first ride. Racing bike . Mounted at the same time as new tires. Puncture with an almost invisible vegetable plug. And to say I hadn't punctured in over a year. I had to spend 25 euros to puncture right away.
