The Ortem Butyl Schrader Valve MTB Tube is a replacement bicycle inner tube designed for mountain bikes and other bicycles with compatible tyres and rims. Made from butyl rubber, it provides reliable air retention and flexibility for everyday riding, commuting and recreational mountain biking.

Dependable Air Retention. Butyl rubber helps minimise gradual air loss, allowing tyres to maintain pressure between rides. Its flexible construction conforms to the inside of compatible tyres, making it a practical replacement for punctured or worn inner tubes during routine bicycle maintenance.

Convenient Inflation. The Schrader valve is compatible with standard Schrader pump heads, including those commonly used for automotive tyres. This makes inflation convenient at home, in a workshop or at compatible air stations. Before installation, check the tyre dimensions and rim valve opening to ensure the replacement tube fits correctly.
