▬▬▬▬ Video Overview ▬▬▬▬
Josh Poertner, CEO of SILCA and host of the Marginal Gains Podcast, introduces the SILCA Ultimate TPU Tubes, a SILCA-fied take on the lightweight inner tube.
TPU tubes have long been fast but limited by lower-cost manufacturing methods that made them more prone to air leaks, valve pullout, and heat-related issues. In this episode, Josh explains how SILCA addressed these weaknesses by reengineering the category from the ground up.
Made in Germany from clear, undyed Thermoplastic Polyurethane (TPU) for superior strength, flexibility, and rolling performance, these tubes feature a patented aluminum valve design, RF butt-welded construction, and a heat-resistant inflation system compatible with SILCA’s modern inflators such as the Hiro Chuck, Elettrico Ultimate, Elettrico Micro, Gravelero, and Tattico Mini Pumps.
Josh also shares how his early frustrations with TPU tubes (and a few flat tires that got him in trouble with his wife) led him to develop something truly better, both as an engineer and as someone trying to live a happy, balanced life.
Key Highlights:
• Patented aluminum valve system: dual flanges mechanically bond the TPU, eliminating weak points and air leaks.
• Clear, pigment-free TPU: made in Germany for strength, flexibility, and efficiency, testing within 0.2–0.3 watts of latex.
• RF butt-welded seams: airtight, durable, and stronger than glued TPU joints.
• Heat-resistant valve assembly: designed for safe inflation with electric and high-flow floor pumps.
• Compact and ultra-lightweight: half the weight and size of butyl tubes.
• Includes adhesive patch and alcohol wipe: simple, reliable repair system for extended service life.
• Optimized for SILCA inflation tools: perfect with Hiro Chuck, Elettrico, Gravelero, and Tattico.
These tubes deliver near-latex performance, ultra-low rolling resistance, and real-world reliability, redefining what a premium TPU tube should be.
