Specialized TPU Gravel Tube Clear, 65mm Valve, 700x35-50mm

What Our Gearhead(R) Experts Are Saying:"I swapped these into my training setup before a long gravel weekend and immediately noticed how much lighter the wheels felt through the climbs. The thorn resistance gave me real confidence on rougher sections of road, and the alloy valve with the removable core made topping up pressure at camp genuinely easy."The road ahead is long, the pack is lean, and every gram you can shed from the wheels makes the whole day feel lighter. The Specialized TPU Gravel Tube is built for riders who care about that calculus, shaving meaningful weight from the rotating mass where it matters most without asking for any compromise on durability or performance. Thermoplastic polyurethane construction puts this tube 60% lighter than a traditional butyl option, drops rolling resistance by 5%, and adds 70% more thorn resistance for the kind of mixed-surface riding that doesn't always stick to clean tarmac. The alloy Presta valve is built to last with a removable core for easy top-ups, and at 65mm it clears deep-section rims without the fumble.
