Squirt Seal 200ml - superior sealant £11.99

This is really good stuff, it costs a bit more than other sealants but we have found it better. From the land of two inch thorns & the Cape Epic ... it's very well tested. One for those important races.

200ml does 2 x 29er tyres easily.

With more long distance events and extreme riding conditions ever increasing, a flat can make life difficult, whether racing or on a social ride. SEAL is a liquid sealant that is inserted into the tyre that will protect against punctures and air leaks. It is compatible with various tyre valves like Schraeder, Presta removable core valves and tubeless. It is ideal for high puncture-risk off-road riding and has been proven by top athletes. It will effectively seal a hole caused by a 10mm-wide thorn or nail and ensure a flat-free ride.
