Redefine your ride with the State Bicycle Co. SuperGravel TPU Tube — built for riders who want a faster-feeling setup, fewer flat interruptions, and a tube that doesn’t weigh down the party. Lightweight, durable, and impressively compact, it’s an easy upgrade for gravel, all-road, and adventure builds. Key Features Optimal Size Fit: Designed for 700c tires in the 45–55mm range (1.75"–2.2") for a snug, efficient fit. 60mm Presta Valve: Perfect for deeper rims and easier access when you’re running chunky rubber. Feather-Light: Roughly ~69% lighter than traditional butyl tubes , helping your bike feel more responsive on accelerations and climbs. Enhanced Puncture Resistance: TPU material delivers excellent resistance to everyday trail and road debris—ride harder, worry less. Supreme Durability: Built for the real world: rough roads, sharp gravel, and long days that would chew up a standard tube. Smooth Riding Experience: TPU’s elasticity helps take the edge off bumps and chatter for a noticeably smoother feel. Stellar Air Retention: Holds air better than standard tubes, so you’re not topping off before every ride. Eco-Conscious Construction: Longer-lasting construction means fewer tubes burned through over time. Extended Lifespan: TPU tubes commonly outlast traditional butyl options by a wide margin—great for high-mileage riders. Compact Size: Packs down small, making it an ideal spare to stash in a saddle bag, frame bag, or pocket. Please note valve stems bodies are non-threaded
