Running tyres ‘tubeless’ – which, as the name suggests, means without an inner tube has many advantages. A tubeless setup is lighter (your bike is minus the extra weight of two tubes), more resistant to pinch flats (so you can run tyres at lower pressure with more grip and more confidence) and because a tubeless tyre will contain liquid sealant, also helps to avoid penetration punctures from thorns and sharp stones.
Tubeless tyres also roll faster – by conforming more readily to the ground and absorbing impacts, rolling resistance is reduced for a faster overall speed.
However not all tyres and wheel rims are ‘tubeless ready’, so if you want to run a tubeless setup on your bike you may need a conversion kit. This normally consists of replacement valves, rim strip (to seal the spoke holes) and sealant.
