Slow puncture (tubeless tyre)

Featured Replies

I’ve got a slow puncher, it turns out the rim tape has a very small split where a spoke has damaged it!

Anyone ever repaired a rim tape with a puncture repair kit?

 

I struggle to get new rim tapes to seal nevermind repaired ones!

Just finished it, put a large patch on the rim seal. It currently seems to be holding 40psi quite well at the moment :unsure:

 

As with most rim tapes, having them hold high pressure is the easy bit lol

True!

I'll leave it overnight with 5psi

Get some stansnotubes sealer from a mtb shop great stuff. Google it and look at their videos

Do away with rim tape

Fit a bolt in valve with O ring

Seal spokes with sikaflex winsdscreen adhesive or dow corning lead and gutter seal. Do not use acetoxy silicone, it will rapidly corrode the rim.

Its an easy enough job to fit a rim tape and get it to seal if you learn the technique.

Big disadvantage with dadies idea is theres too much risk that in a trial the rim will leak and doesnt allow any spoke adjustment going forward.

Never had a problem getting a seal, just make sure everything is clean and well lubed

The puncture repair seems to be holding even at low pressure :thumbup:

Wouldn’t it be easier just to fit a rim tape? :rotfl:

I had a similar problem about a year ago, the air was escaping around a couple of spokes. I ended up sticking a tube in, it was tight and it took a couple of hours to get it in. :mellow: If your solution doesn't hold up, try a tube. :D

we've been here before. Grip is lost with a tube in.

I'm by no means the best mechanic in the world but fitting a rim tape isn't that hard. Once it's in properly it last for years.

I've ran tubes before in a split tyre, fitted a patch to the inside wall. It's ok short term but if you get a puncture you are out of the trial unless you can get back to the van and generate enough pressure to fit another one. It can also damage the rim at the valve hole when the tube slips.

One trial later and the rim tape still holds pressure, so rim tapes do repair :thumbup:

Well done. I notice a bulge in the rim tape(?) if so, put the tyre back on and leave 60 psi for a few days and it will flatten out nicely!
