Silca TPU Inner Tube

The Silca TPU tube is significantly lighter and more compact than a standard butyl tube, making it an excellent choice for reducing rotational weight and saving space in your saddle bag. While it offers faster acceleration, it requires careful installation to avoid pinching, unlike more forgiving rubber tubes.

No, these TPU tubes are designed specifically for disc brake wheels. The heat generated by rim brakes can cause the TPU material to soften and fail, leading to a blowout.

These tubes are optimized for 700c tires commonly used in road, gravel, and cross-country cycling. Always check your specific tire width against the manufacturer's recommended range to ensure a proper fit and prevent tube damage.

Each tube comes with a dedicated glueless patch kit. These patches are designed specifically for the TPU material, allowing for quick, reliable repairs without needing to carry messy glue or wait for it to dry.

Yes, the Silca Ultimate TPU tube features a removable Presta valve core. This allows you to easily install valve extenders if you are using deep-section aerodynamic rims.

A mechanically attached aluminum valve stem provides a much more secure and robust connection to the tube body compared to standard glued interfaces. This design significantly reduces the risk of leaks or separation at the valve base, which is a common failure point in lesser TPU tubes.
