Ultra-lightweight. Compact. Fast.

The Race Formula Ridenow TPU Inner Tube is a high-performance 700c road bike inner tube made from thermoplastic polyurethane (TPU), delivering a significant weight and pack-size reduction compared with conventional butyl tubes.

At just 36g, it weighs up to 70% less than a traditional butyl inner tube while taking up around 50% less space when packed. That makes it an ideal spare for racing, training or long rides where every gram and every bit of storage space counts.

The TPU construction also offers reduced rolling resistance, helping create a fast, responsive setup for road bikes running tyres from 18–32mm wide.

Race Formula's latest TPU + metal composite valve provides improved durability, strength and airtightness compared with conventional TPU valve designs. The removable valve also makes the tube practical for riders using deeper-section wheels.

Available in bright colours for easy identification in your saddle bag or workshop.

Important Installation & Inflation Warning

Do not inflate the tube outside of a tyre.

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

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

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