STRONG. LIGHT. AFFORDABLE.

Yes, it's possible to have all three. Thermoplastic Polyurethane (TPU) Tubes are an innovative and high-performance alternative to conventional bicycle tubes. Like any new technology, it's usually expensive, and TPU tubes were once reserved for the cycling elite, costing up to 5 times more than a regular rubber tube. Entity has teamed up with the industry leader in TPU, RideNow, to bring you a 60% reduction in weight, improved puncture protection, enhanced riding dynamics, and ease of use compared to rubber tubes - all at an affordable price point.

LIGHTWEIGHT SPARE

Its feather-light construction and easily rolled-up compact design make it the ideal spare – a powerful solution in a small package for tubeless and tube riders alike.

PUNCTION PROTECTION REDEFINED

TPU significantly reduces the risk of punctures and offers advanced puncture resistance compared to traditional rubber tubes for a worry-free cycling experience.

OPTIMIZED ROLLING DYNAMICS

Enjoy a smooth and efficient ride with minimal rolling resistance, enhancing your cycling performance on various terrains.

VERSATILE AND HASSLE-FREE INSTALLATION

Designed for compatibility with both disc and rim brakes, the Entity TPU Tube provides easy and secure installation without slipping or pinching, catering to riders of all skill levels.

Whether you're looking to save some rotational mass to squeeze out extra watts on your road bike, searching for an ultra-lightweight spare to carry on your rides, or seeking a lightweight alternative to tubeless without the hassle of sealant, check out the Entity TPU tubes.

BONUS TIP: These tubes are an excellent option to pair with TANNUS tire armor for the ultimate setup to prevent punctures on your commuter or mountain bike!

NOTE: Do not use tubes outside the recommended tire size specs, as TPU tubes unlike rubber tubes do not stretch as much, which could lead to unwanted punctures.
