“I've always used Stan's sealant but I saw this at 99 bikes and it was way better value for money so far it works great”
“Good product and easy to use. The online tutorial video which was found on the 99 Bikes website helped enormously.”
“I have used the Schwelbe version but this is much thicker, not too thick but just right. Works very well.”
“Excellent product, great value for the bulk quantity, highly recommended.”
“I think it's one of the best sealant around..easily last 5 months even during summer”
