01 Vittoria Universal Tubeless Tyre Sealant 500ml

£19.99 

3.5/5

AVAILABLE IN FIVE SIZES FROM 80ml to 1L, the Universal is ammonia and scent-free. It's also latex free so won't result in an allergic reaction. Vittoria claim it will seal holes up to 5mm long and not 'ball' or congeal in the tyre, while it's targeted for use on road, gravel and mountain bike tyres. At 80psi (5.5 bar) the sealant performed well, sealing a thin knife incision 8mm-long having already sealed two separate attacks with a large, sharpened screwdriver. An interesting specification is that the Universal sealant won't freeze above -15°C. I wasn't about to put that to the test, but it's good to know.
