Pirelli Cinturato SmarTUBE Lite - 29"x35-50c / 650x35-50c - Yellow

Following the technological success of Pirelli's SmarTUBE developed for high-performance road racing applications, Pirelli now extends its new TPU formulation to off-road riding with the new SmarTUBE Lite family. Specifically engineered for Gravel and MTB applications, the SmarTUBE Lite range has been designed to meet the needs riders who demand lower weight, reduced rolling resistance, and high versatility without compromising reliability. Dual-diameter compatibility allows a single tube to fit two wheel diameters, 29" and 27.5"/650b. Combined with a very wide tire width range, and its compactness makes these a perfect spare to bring on your off-road rides. Mullet setup? Just bring one SmarTUBE Lite.

Cinturato SmarTUBE Lite is designed to deliver a tangible upgrade in efficiency, weight, and packability, key factors for modern gravel and off-road riding. When compared to traditional butyl tubes, the advantages become even more evident, especially for riders looking to optimize both performance and practicality; lighter, lower rolling resistance and comparable puncture resistance. Thanks to this combination of low weight, improved rolling efficiency, and balanced durability, along with its dual-diameter design and wide tire compatibility, Cinturato SmarTUBE Lite stands out as a versatile solution for modern gravel and endurance off-road setups.

Compared to standard Cinturato SmarTUBE:

• 28.6% lighter - Reduces rotating mass, making the bike feel faster and more responsive
• 37.5% thinner - More compact and easier to carry in a pocket or saddle bag, ideal as a space-saving spare tube
• 6.3% rolling resistance - Improves riding efficiency, helping you maintain speed with less effort
• Virtually unchanged air retention (-0.14%) - Ensures consistent pressure and reliability
