| 24/9/2017 7:09 PM Saved my bacon this week... but not 100% by Chris have used this twice now. First time it failed (it slowed the leak but didn't fix it). Second time a charm, fixed the leak without having to remove the wheel / tube. Brilliant! you still need to pump the tyre up after if you want any reasonable pressure but it's a darn site faster and easier than changing a tube.It seemed to take a while for the latex to "set" - I had to do two injections to get enough in there to actually stem the leak; after the first it was literally blowing bubbles but after the second injection it finally plugged it up. Have been riding on the tyre @ 120psi (road tyres) since then no dramas.The cap leaks a bit when you're loading which makes it a bit messy. If this was improved and the hitrate was 100% then 5 stars... but still pretty bloody good.
