The Ultimate Performance Upgrade.
The Rocket TPU Inner Tube is a high-performance alternative to traditional butyl tubes, designed specifically for riders looking to reduce rotating mass and improve rolling efficiency. Made from Thermoplastic Polyurethane (TPU), these tubes are significantly lighter, more compact, and offer superior puncture resistance compared to standard rubber tubes.
This specific model is tailored for modern road and gravel setups, fitting tire widths from 25mm to 32mm. The extra-long 100mm Presta valve is a critical feature for riders using deep-section aero wheels (60mm to 80mm depth), eliminating the need for finicky valve extenders and ensuring a secure, airtight pump connection.
Key Features
Ultra-Lightweight Construction: Weighing a fraction of a standard tube, it reduces peripheral weight on the wheel for faster acceleration and easier climbing.
100mm Reinforced Valve: The extra-long integrated valve stem is designed for deep-profile carbon rims, featuring a reinforced base to prevent leaks at the high-stress junction.
Low Rolling Resistance: The material properties of TPU minimize internal friction between the tube and tire, resulting in a smoother, faster ride similar to a tubeless setup.
Superior Puncture Protection: TPU is naturally more resistant to pinches and sharp objects than butyl, providing increased reliability on debris-strewn roads.
Compact Packability: When folded, these tubes are roughly 1/3 the size of a standard tube, freeing up significant space in your saddle bag or jersey pocket.
High-Heat Resistance: Engineered to withstand the temperatures generated by rim brakes, though they are equally optimized for modern disc brake systems.

✅ Ideal For
Aero Road Specialists: Riders using 60mm+ deep-section wheels who want a lightweight, one-piece tube solution without valve extenders.
Weight Weenies: Cyclists looking for the most cost-effective way to drop 100g+ of rotating weight from their wheelset.
Space-Saving Commuters: Perfect as a backup tube because it takes up minimal room in a small saddle bag or top-tube bag.
❌ Considerations
Installation Care: TPU tubes must not be inflated to more than 5-8 PSI outside of the tire, as they can permanently deform or burst without the casing's support.
Specific Patch Kits: Standard rubber cement patches will not work; ensure your customers know they require TPU-specific adhesive patches for repairs.
Initial Cost: While performance gains are high, the unit price is higher than bulk-buy butyl tubes, reflecting the advanced material technology.
Pro Tip
When installing a Rocket TPU tube, use a small amount of talcum powder or ensure the inside of the tire is clean. Because TPU is so thin, it is easier to "pinch" during installation compared to thick rubber. Always hand-seat the last section of the tire bead rather than using levers to avoid snagging the tube. For riders using very deep rims, the 100mm valve ensures enough clearance to fit almost any track or floor pump head comfortably.
