Michelin C4 Protek Max Mountain Bike Inner Tube - With Sealant}
  • £3.99
  • RRP £12.99
  • Saving you £69

Michelin C4 Protek Max Mountain Bike Inner Tube Punctures due to perforation or nipping impact (edges of sidewalks in the city or rocks for mountain bikes, etc.) are a major fear among all cyclists. Repairing or changing an inner tube is not always a very simple operation. An inner tube must be regularly re-inflated.Thanks to its uneven design, the MICHELIN Protek Max inner tube undergoes a "compression" reaction in the event of piercing or nipping (the hole closes up naturally), whereas a classic inner tube has an "extension" reaction (balloon effect).This self-plugging effect is enhanced by adding the preventive sealant originally supplied.Features: Exceptional puncture resistance Self-sealing liquid inside Valve: Presta 40mm Width Capacity: 47/58 Diameter Capacity: 559 Weight: 330gBuy Michelin Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
