About this item
- Size Compatibility: Spingo Ultra-Light TPU Inner Tube 700c fits gravel road bike tires from 35mm to 43mm (35c /38c / 40c / 42c / 43c). One lightweight TPU inner tube covers multiple sizes, making it an ideal replacement tube for gravel road cycling, racing, and daily training. Fully compatible with rim brake and disc brake systems, it delivers reliable performance in all riding conditions.
- 48mm Presta Valve – 48mm / 60mm / 80mm: Match your rim depth—48mm standard. This ultra-light TPU inner tube upgrades 700c gravel bike tires for quicker acceleration, better road feel, and responsive handling. Ideal for cycling, climbing, racing, training, and commuting—a durable, lightweight bike tube replacement.
- Upgrade TPU Material: The Spingo Gravel TPU Tube 700c is up to 70% lighter than traditional butyl, reducing rotating weight for faster acceleration and climbing. A smart upgrade from butyl, this lightweight road bike inner tube offers excellent air retention, durability, and a compact design, delivering race-level performance with everyday value for road racing, training, and high-speed riding.
- Portable & 56g Ultra-Light: SPINGO TPU tubes can Pack down to 4.45in × 1.38in × 1.18in, making it far more portable than traditional butyl tubes—easy to stash in a saddle bag or jersey pocket. At just 56 grams, this Gravel TPU inner tube 700c saves up to 110g per wheel vs butyl inner tubes for better handling, faster climbs, and a smoother ride. The 56g TPU build is more durable than ultra-thin 26g TPU tubes, with strong puncture resistance—an ideal lightweight road bike inner tube.
- Easy Install for Road Bike: SPINGO TPU tubes match the 700c road bike tire size, check rim tape, and remove debris inside the tire. Slightly pre-inflate (max 0.5 PSI), insert the Presta valve straight, tuck the tube evenly (no twists), and mount the bead slowly to avoid pinch flats. Check both sides for any tube showing before inflating. Never exceed 5 PSI outside the tire. Need help? Message us anytime for support.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
