- Upgraded Aluminum Valve Stem: Made from premium aluminum alloy, it offers metal-like strength and durability while staying lightweight—only 2g heavier than a plastic valve TPU tube and about 5g lighter than a metal valve TPU tube. Resistant to deformation, corrosion, and wear for reliable long-term use.
- TPU Material: The Spingo 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.
- Three Presta Valve Options – 48mm / 60mm / 80mm: Match your rim depth—48mm standard, 60mm mid-depth, 80mm deep carbon rims. Spingo Ultra-Light TPU Inner Tube 700c fits road bike tires from 23mm to 32mm (23c / 25c / 28c / 30c / 32c), for quicker acceleration, better road feel, and responsive handling.
- Portable & 48g 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 48 grams, this TPU inner tube 700c saves up to 110g per wheel vs butyl inner tubes for better handling, faster climbs, and a smoother ride. The 48g 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.
