Silca TPU Tube
Product Details
The Silca TPU Tube delivers a revolutionary approach to spare tube carrying, combining ultra-compact design with reliability engineering that transforms TPU technology from a space-saving convenience into a dependable performance solution. Long favored by cyclists seeking to maximize saddle bag efficiency, TPU tubes now address the durability concerns that previously limited their appeal through patented mechanical innovation and thoughtful material selection.
Traditional TPU tubes suffered from predictable failure points, plastic valves detaching from the tube, valve cores pressed into plastic, causing leaks, and sleeve joints failing under use. Silca engineered a comprehensive solution: patented technology mechanically attaches the valve directly to the tube, while welded construction eliminates joint failures entirely. A threaded aluminum valve resists heat from electric pumps and provides superior durability, while an included valve nut ensures a rattle-free, completely secure design. When you need that spare tube, it will perform reliably rather than fall apart.
Recent advances in TPU materials have narrowed the performance gap with traditional options. Silca's TPU tubes now deliver rolling resistance efficiencies that rival latex tubes and tubeless setups while weighing a fraction of butyl alternatives. Ranging from 45–62 grams, these tubes achieve unprecedented weight efficiency while maintaining the compact profile that defines TPU technology. The tubes are less than half the size of traditional butyl tubes, allowing riders to carry two spares instead of one or reduce tire weight by over 200 grams by replacing butyl tubes entirely.
Whether optimizing weight for competitive riding or maximizing space in a saddle bag for extended adventures, the Silca TPU Tube combines innovative engineering with practical performance that makes ultralight, reliable spares finally achievable.
