High Pressure FRENCH (PRESTA) Valve Inner Tube - CST

CST High Pressure Inner Tube with Standard FRENCH / PRESTA Valve

Wheelchair Tire Inner Tubes

Most wheelchairs use high pressure inner tubes. To see if your wheelchair needs high pressure tubes, take a look at the sidewall of your tires. If the psi required is above 40psi, we recommend you use these CST High Pressure tubes.

High Pressure FRENCH (PRESTA) Valve Inner Tube - CST Buyer’s Guide

The High Pressure French (Presta) Valve Inner Tube by CST is a high-performance replacement tube engineered specifically for high-pressure wheelchair tires. Designed to maintain optimal inflation, support low rolling resistance, and minimize rotational weight, this CST tube is an ideal choice for active manual wheelchair users requiring maximum efficiency and speed.

CST High-Pressure Inner Tube Compatibility

Built to handle elevated PSI ratings common in active, sport, and daily rigid wheelchairs, this tube ensures superior air retention. By maintaining firm tire pressure over extended periods, it prevents drag, improves coasting distance, and protects rims from pinch flats.

Presta (French) Valve Design

Featuring a slim Presta valve with a threaded valve stem and secure locking nut, this design creates a tight seal against high air pressure. Presta valves are smaller in diameter than standard Schrader valves, maintaining structural strength in narrow high-pressure wheelchair rims and enabling quick, precise pressure adjustments.

Puncture-Resistant Butyl Rubber

Constructed from high-grade, high-elasticity butyl rubber, the CST inner tube resists punctures, tears, and everyday wear. The durable compound flexes smoothly inside the tire casing, absorbing minor road debris without sacrificing pressure integrity.

Lightweight Low-Rotation Construction

The lightweight design reduces rotational mass on the wheels, making push effort easier and less tiring on the user's hands, wrists, and shoulders. Less weight per revolution directly translates to snappier acceleration and smoother overall wheelchair maneuverability.

Versatile Wheel Size Options

CST offers this tube in multiple diameter and width configurations (including standard 24", 25", and 26" / 540mm, 559mm, and 590mm sizes), making it compatible with a wide range of everyday and high-performance wheelchair tires.
