Review: Bought 4 all have held pressure - I ride the road bike tires at 70psi on 30mm contis. These save about 80g over latex and 180g over butyl. They do lose ~20psi pressure over 2weeks so need to keep an eye on that. Haven’t noticed the noises when riding that others mention. They ride well and are small and light. Also easier to put on than butyl. Expensive but not crazy expensive - I would be a bit worried about how well they would survive in the saddle bag for a few months waiting to be used in event of a puncture but I guess we will see. Certainly a relatively cheap way to lose rotational weight - losing 200g off my wheels would cost a lot more than £24
Review: Waste of money - Yes they are light but quality is poor. One developed a major tear and the other a slow leak within a week of install. Waste of money.
