24g. That's it.

The Race Formula Ridenow Superlight TPU Inner Tube is built for road riders chasing every last gram. At just 24g, it's approximately 33% lighter than the standard Ridenow TPU road tube, making it one of the lightest practical spare tubes for a modern road bike.

Made from thermoplastic polyurethane (TPU), the Superlight tube combines an exceptionally low weight with reduced rolling resistance and a compact packed size. It's particularly suited to racing, climbing and weight-conscious builds — or simply carrying as a minimalist spare tube without filling your saddle bag.

Race Formula's updated TPU + metal composite valve provides improved strength, durability and airtightness, while the removable valve adds practicality.

The Superlight is specifically designed for disc brake wheelsets and road tyres from 18–28mm wide.

Important Installation & Inflation Warning

Do not inflate the tube outside of a tyre.

Due to the composition and stretch characteristics of TPU, the tyre carcass is required to support the tube during inflation. Inflating a TPU tube outside of the tyre can cause irreparable damage.

This damage is not a manufacturing fault and will void the tube's warranty.

Always install the tube fully inside the tyre before inflating and follow the manufacturer's recommended installation procedure.
