SILCA Launches Ultimate TPU Tubes: The Premium Lightweight Alternative to traditional butyl and latex tube set ups.

Indianapolis, IN/Amsterdam (NL) — OCT 14th, 2025 — SILCA, a leader in precision cycling equipment, announces the launch of its Ultimate TPU Tubes, an advancement in bicycle inner tube design.

Made in Germany from clear uncolored or dyed Thermoplastic Polyurethane (TPU), the SILCA Ultimate TPU Tubes are engineered to deliver unmatched reliability, compact portability, and real-world performance as both a dependable spare and a premium upgrade to butyl tube set ups!

At less than half the weight of traditional butyl tubes (45g vs 150g for 700x35mm) and packing down to less than half the size, the Ultimate TPU Tubes offer cyclists a better option to carry spares. Riders can carry them easily in a jersey pocket or saddle bag without sacrificing space or performance.

With some of the lowest rolling resistance of any tube material 2-4 watts saved and compatibility across both rim and disc brake systems, SILCA TPU Tubes provide an edge while also excelling in gravel and MTB applications. Sizes range from 24–43 mm for road (50mm and 70mm valve) to 44–64 mm for off-road 50mm valve, ensuring versatility across riding disciplines.

• Clear TPU Construction — Made without dyes or pigments which can reduce strength and elongation performance in plastics and increase rolling resistance.

• Ultimate Rolling Efficiency – Within 0.2 watts of Latex Tube rolling resistance, and 2-4 watts faster than butyl.

• Patented Mechanical Valve Bond — TPU material sandwiched between aluminum flanges eliminating stresses caused by pump head installation and removal, which is the most common TPU tube failure mode.

• Threaded FULLY Aluminum Valve with Locking Nut — Guarantees a secure pump connection during roadside or trailside inflation. Movement in valves while inflating can cause friction-based punctures around the valve. No plastic bonding in the valve.
• Removable Valve Cores & Extender Compatibility — Flexible for deep rim setups.
• Heat Resistance During Rapid Inflation — Engineered to withstand the heat generated by modern high-flow pumps and electric pumps

• Field Repair Ready — Each tube is packaged with an adhesive patch kit and alcohol prep wipe, making each tube effectively 2 spares when carried as a backup.

Designed with today’s pumps in mind, including SILCA’s ELETTRICO electric pump, the TPU Tubes maintain performance and safety when inflated in 15 PSI steps, preventing the heat-related failures common to other TPU tubes.

Like all SILCA products, the Ultimate TPU Tubes are backed by SICLA’s renowned commitment to quality and customer satisfaction. Priced at $39 USD (MAP), they represent the ultimate balance of lightweight performance, durability, and reliability.
