Perfect for cycling, mountaineering, racing, training and commuting - a durable, lightweight replacement tube for road bikes. Upgraded TPU Material The SPINGO TPU Tube 700C is up to 70% lighter than traditional butyl, which reduces rotation weight and leads to faster acceleration and better climbing properties. A smart alternative to the butyl tube, this lightweight road bike inner tube offers excellent airdensity, durability and a compact design - ideal for road racing, training and high speed riding. Portable & 45g Ultralight: SPINGO TPU tubes can be compressed to 11.3 cm × 3.5 cm × 3 cm, making them significantly more portable than conventional butyl tubes - perfect for storing in a saddle bag or jersey pocket. At only 45 grams, this TPU inner tube saves up to 110g per wheel compared to butyl inner tubes, resulting in better handling, faster climbs and a smoother ride. The 45g TPU tube is more resistant than ultra-thin 26g TPU tubing and provides strong puncture resistance - ideal for lightweight road bike inner tubes. EASY INSTALLATION FOR ROAD BIKES SPINGO TPU tubes fit the 700C road bike tire size, check rim tape and remove dirt in tire. Lightly pre-inflate (maximum 0.5 PSI), insert Presta valve straight, clamp the hose evenly (without rotation) and slowly mount the bead to avoid punctures. Check both sides to ensure no hose is visible before inflating. Never exceed 5 PSI outside the tyre. Need support? Contact us anytime!
