MTB: Peaty's Tubeless Sealant Review

If you want to use tubeless tyres (i.e. not have to use inner tubes) you usually have to add some form of liquid sealant to stop small leaks etc. Here’s my experience with Peaty’s Tubeless Sealant.

Pros:

  • Easy to use, quite liquid, easy to clean up
  • Works (eventually) to seal tyre fits, small holes, tears in rim tape etc.

Cons:

  • Takes a lot longer to seal small holes/punctures than I expected – up to 48 hours
  • Doesn’t seem to stop some slow leaks
  • Seems to be ineffective on sidewall cuts

Overall impressions

Am slightly ambivalent about Peaty’s Tubeless, to be honest. It’s relatively easy to use, but I am not that convinced it is effective.

While it has usually sealy sealed small holes/leaks for me, it has usually been quite slow to do so – i.e. it’s taken days – so am not sure how reliable it will be on the trail.

When I had a slash/cut on a sidewall, it was ineffective.
