Silca Ultimate TPU Bicycle Tube 700 x 24-43 w/ 70mm Valve

Compact, light, and engineered to actually hold up in the field — the SILCA Ultimate TPU Tube for 700 x 24–43mm tires with a 70mm valve is the smart choice for riders who want the packing efficiency of a TPU tube without compromising reliability. At just 46g and folding down to 39mm x 95mm x 21mm, two of these fit easily in the space a single butyl tube used to occupy.

SILCA's patented valve attachment mechanically bonds the threaded aluminum valve to the tube body, solving the detachment problem that has plagued cheaper TPU tubes. A welded sleeve joint eliminates the other common failure point. The threaded aluminum valve core resists heat from electric pumps and accepts a valve nut for a rattle-free, secure fit in deep-section rims.
