The Ortem Butyl Presta Valve Road Tube is a replacement inner tube designed for road bicycles with compatible tyres and rims. Manufactured from butyl rubber, it provides dependable air retention and flexibility for everyday training, commuting and recreational road cycling.

Reliable Air Retention. Butyl rubber helps minimise gradual air loss, allowing tyres to maintain pressure between rides. Its flexible construction conforms to the inside of a compatible tyre, making it a practical replacement for a punctured or worn inner tube. The material is suitable for regular road cycling where consistent inflation and straightforward maintenance are important.

Convenient Inflation. The tube features a Presta valve for inflation with compatible bicycle pumps. Its valve design is suitable for road rims with the appropriate valve opening and sufficient clearance. Before selecting a replacement, riders should check their tyre size, rim compatibility and valve length to ensure correct fitment.
