The Silca Ultimate TPU Tube is designed for riders who want the speed and efficiency of tubeless with the convenience of an inner tube. Made from advanced Thermoplastic Polyurethane (TPU), this high-performance tube is exceptionally lightweight, compact, and durable, making it perfect both as an everyday inner tube or an ultra-packable spare.

Weighing around half the weight and size of traditional butyl tubes, the Silca Ultimate TPU Tube easily fits into a jersey pocket, saddle bag, or tool roll, making it ideal for long rides and race-day emergencies. Despite its compact size, the clear TPU construction provides excellent strength and puncture resistance, while also delivering lower rolling resistance than many traditional and TPU alternatives.

Designed for reliability and longevity, both the TPU tube and aluminium valve stem resist heat build-up, helping maintain consistent performance and durability even during long descents or high-pressure use.

Manufactured in Germany, the tube features a patented mechanical valve connection that is securely bonded to prevent pull-out during repeated installations. A threaded aluminium valve with locking nut ensures a secure fit in the rim, while the removable valve core allows compatibility with deep-section rims and valve extenders.
