Bontrager Self-Sealing Presta Valve Bicycle Tube

The tube is pre-filled with a sealant compound that flows to the site of a puncture when air pressure escapes. As the air rushes out, it forces the sealant into the hole, creating an instant, durable plug so you can keep riding without stopping to change your tube.

This tube is compatible with a wide range of common sizes, including 26-inch, 27.5-inch, 29-inch, and 700c wheels. Please check your tire sidewall for the specific width and diameter to ensure it falls within the compatible ranges listed in the specifications.

Yes, the 0.9mm wall thickness is engineered to strike a balance between weight savings and puncture resistance. While it is robust enough for general trail and road use, it is still a standard-weight tube, so it remains lightweight and responsive.

No, you can use any standard bicycle pump designed for Presta valves. The 48mm valve length is standard for most rim depths, but if you have deep-section aero rims, you may need a valve extender.

Yes, you can patch this tube just like a standard butyl rubber tube. However, because of the internal sealant, you will need to wipe the area clean and dry thoroughly before applying a patch to ensure a proper bond.
