Product Description

The Pirelli SmarTUBE RS is a next-generation inner tube built for speed, lightness, and reliability. Using a new thermoplastic polyurethane (TPU) compound, it is up to 21% faster than the original SmarTUBE. Designed to rival the performance of tubeless setups without the added maintenance, it sets a new benchmark for efficiency and ease.Key Features and Benefits:Advanced TPU formulation with reduced hysteresis: The latest thermoplastic polyurethane compound lowers rolling resistance by up to 21%. This gain turns into higher efficiency on every ride, meaning less wasted energy and faster speeds over the same effort.Ultra-lightweight construction at 32 34g: By shaving grams without losing durability, the SmarTUBE RS reduces rotating mass at the wheel. The result is quicker acceleration, sharper handling, and less fatigue over long distances.Enhanced puncture resistance from refined material design: The TPU structure balances elasticity with resilience, creating a strong barrier against sharp objects. This increases reliability on varied surfaces, lowering the risk of flats cutting a ride short.Comparable rolling performance to sealant-based tubeless systems: Independent testing shows speed levels on par with premium tubeless setups. Riders gain the efficiency of tubeless, without the need for liquid sealant or ongoing upkeep.Compact size for easier packing and storage: The material allows the tube to fold down smaller than standard butyl options. This saves space in a jersey pocket or saddle bag, making it practical to carry spares on any ride.Available in multiple valve lengths (42/60/80mm): With consistent weights across options and a sleek black stem, the tube integrates cleanly into both aero and standard rim depths. This ensures wide compatibility without compromise on looks or performance.Riders looking for maximum speed gains often weigh the complexity of tubeless against the simplicity of tubes. SmarTUBE RS changes this equation. It combines low rolling resistance, light weight, and robust puncture protection in one system. By doing so, it makes high-level performance achievable with fewer steps, less maintenance, and broader compatibility.The SmarTUBE RS brings speed, reliability, and practicality together in one design. If you want a tube that delivers top-tier performance while keeping setup simple, this is the clear choice.Specification: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 removable valve core.Weight: 42/60/80mm valve - 32/33/34gFor 700 x 26-35c size tyres
