Has anyone had one work on a road tube?
Used one the other day when we had a jammed bolt through axle, so repaired the tube in-situ. The patched leaked after about 5 miles - pumped it up to a lowish 50/60 psi as well.
Been carrying them for decades but first time I've ever used one, were we just unlucky?
yeah worked well at road pressure for me, i like to give it a couple of minutes before inflating.
A lot can depend on the location of the patch really though. Anywhere near the valve is a no.
yep - quite a few times. No problems. Have to be careful not to get the sticky side dirty/gritty - then they won't do the job.
They do seem to lose their stick after an extended period (yrs), but as a slow puncture and just change the tube at that point.
ok, sounds like we were just unlucky. NB We didn't wait 2 mins before inflating....
In the end we changed the tube - I jammed a hex key in one end of the bolt through axle, took my shoe off and hammered the axle out using the heal of my shoe! No idea why it wouldn't budge, brand new Cervelo, the owner had never taken a wheel off.
I've never used the park patches but have had success with 'scabs' I think they are called. Self adhesive with a foam top. The last road bike puncture I fixed I was surprised to find when I got back I had managed to get 75psi into the tube too.
The Lezyne ones are pretty reliable
I was always told when I started using them years ago that they weren’t meant to be used with high pressures like on road bikes.
Bit hit and miss here.
Basically if the tyre is at all damp or partially inflated when putting them on they do seem to fail for me. And as above, any small grit / finger print patches are not conducive to them staying put.
Bit hit and miss, but the best I've found, and never had an issue with a road tube at 90 PSI other than the points above, which were generally MTB tyres.
