Rims are tubeless ready. Any recommendations?

Stans and you may need to top it up every 6 months. The quart bottle should last an age. Avoid the CO2 cylinders as they seem to react with the sealant and you get big balls of sealant in the tyre. I think it is the extreme cold from the CO2 when injected into the tyre.

If you’ve tubeless tyres and tubeless rims I’d go for the cheapest I could find.. Stans or Joes NoFlats if your tyres need a little help holding air.

I use noflats – seems to work fine. 100ml per tyre.

I think it is the extreme cold from the CO2 when injected into the tyre.

I think it’s actually the CO2 acting as a coagulant upon the latex – which is part of the reason that sealant ‘dries’ out: CO2 in the atmosphere slowly coagulating the latex component of the sealant whilst the other liquids slowly evaporate.

Thanks for the above info wondered why I was getting the balls!
