Silicone balls in tubeless tyres

[Ysterperd]

I have been using Stans up to now and have had the experience of both the balls and the latex linning all round the inside. thinking of switching to Bat seal going forward - apparently they maintain that they have elimanted this problem.

The difference between sealants was explained to me this way by Johan Bornman on a maintenance course.

There are 2 types of sealants used in bicycle tyres namely latex based and glycol based.

Latex is a natural plant sap which needs to be preserved otherwise spores get in and it rots. Ammonia is used as the basic preservation chemical. This mixture which is approximately ph neutral reacts by coagulating when exposed to acidity introduced by a co2 bomb and creating balls or coral structures. Co2 bombs should only be used to get home then the latex sealant needs to be replaced.

Glycol sealants do not react to co2. They have a lifespan of most tyres but are slightly less efficient as they block puncture holes due to their viscosity but do not seal like latex which effectively bonds like a glue when sealing the hole.

 

Catch 22. Latex seals better. Glycol lasts longer. Sounds like a 26v29er type debate all over again. Both are better than tubes imho.

I been cycling for many,many years and have neved used a bomb nor felt like it is something I should cary with me ! Please remind me again why a pump is a kuk idea !?? And therefor the only balls I got/get are steel .

If you get a puncture (a cut in the sidewall) which the sealant for obvious reasons will not seal. If you take the tire off to place a gator over the cut, resealing the tire sometimes requires a "kick" to seat it again which you might not achieve with a hand pump.

 

Then again, guess you could also revert to a tube as a quick fix and use the pump. Whatever floats your boat.
