Make sure you’re always prepared for punctures with the Slime Smart Self-Healing Inner Tubes. Pre-filled with a fast-acting and environmentally-friendly Slime sealant, this pair of powerful tubes seal punctures up to 3mm in size and prevent flat tyres for up to 2 years.
The microfibers in Slime's patented formula are carried by the escaping air to the puncture, where they build up to form a plug that stops air loss and seals the puncture.
Designed for Presta valves, you can take on rough and ready runs with confidence, without letting punctures hold up your journey. And for those commuting, punctures will never disrupt your regular ride to work when you’ve got Slime’s super reliable tubes to hand. Altogether, these self-sealing tubes keep your riding for as long as possible with minimal fuss.
