This extremely light thermoplastic polyurethane (TPU) tube is the ultimate choice for performance-driven riders, offering maximum puncture protection in a remarkably lightweight package. Designed for minimum rolling resistance, this robust material is specifically engineered to resist snake bites and sidewall damage for a more reliable ride.

Technical Versatility: The tube features a 40mm Presta valve with a removable core, making it perfectly suitable for valve extensions. While the TPU material is incredibly tough, please note that puncture sealing liquids do not achieve a sealing effect with this material and their usage is not recommended for this specific tube type.

Precision Fit: Optimized for 29" tires, these tubes come in a variety of widths including 23-28c, 28-35c, and 37-50c to match your specific setup. Each tube is individually boxed with easy-to-identify size and valve graphics, with the 700x23-28c model weighing in at an impressive 41g to keep your rotating mass to a minimum.
