Had a couple of these puncture bbut never been able to repair them very well.
Both have gone down after 24 hours due to the inner tube ripping inside the patch.
I normally use Park self adhesive patches.
Have you safely repaired these tubes and if so what repair kit did you use?
I wont be buying anymore though for an extra 20 grams I'll buy Michelin air lights in future.
