Specialized Tubes|700c TPU Inner Tube (Presta) (25 – 35mm) (65mm)

Specialized 700c TPU Inner Tube Description:

The Specialized 700c TPU Inner Tube is a phenomenal upgrade for any traditional tube and tire setup and is a high-performance tube option for a flat repair kit. TPU is a much lighter substance than the butyl rubber used in traditional bicycle tube construction and is much more puncture resistant. This tube will also reduce rolling resistance, and when it comes to using this tube in a flat kit, they take up about half the space that a normal tube would so there is more room in the bag or pocket for other gear. Finally, an aluminum alloy valve stem with a removable core allows damaged valve cores to easily be replaced as well as allowing valve extensions for deep dish wheels to be installed, and multiple sizes are available to fit virtually any road or gravel bike.

Features:

• Thermoplastic Polyurethane, or TPU, construction is significantly lighter, reduces rolling resistance, and has better puncture resistance than a butyl rubber tube
• Aluminum valve stem with a removable valve core enables the ability to attach valve extensions so these tubes can be used with very deep aerodynamic wheels
• TPU tube takes up less space in pockets or bags than rubber inner tubes, leaving more space for a second tube, tools, or other ride essentials
• Compatible with rim and disc brake style wheels, and can be used on or off road
