Smartube RS – Redefining Inner Tube Performance. Introducing the upgraded Smartube RS: engineered to be up to 21% faster than the original Smartube, lighter and featuring enhanced puncture protection. Thanks to a brand-new Thermoplastic polyurethane formulation, Smartube RS sets a new standard—delivering unmatched performance, reliability, and versatility.

Whether you’re using Tube Type or Tubeless Ready (TLR) tires, Smartube RS integrates seamlessly into your setup. Testing proves it offers rolling speeds comparable to sealant-based tubeless systems—without the mess or maintenance.

No compromises. No complications, just pure speed, made simple. Pair it with our P ZERO Race RS tires for the fastest, most efficient system we’ve ever created.

• NEW (TPU) Thermoplastic polyurethane formulation up to 21% faster than Smartube. Further development of our TPU material, now with even lower hysteresis for lower rolling resistance, at the same weight and compact volume as before. 
• Available in 42/60/80mm valve lengths, yellow tube with a black valve stem and non removeable valve core.
• Weight: 42/60/80mm valve - 32/33/34g
