Maxxis Flyweight Tubes

While they offer a significant weight advantage, their ultra-thin 0.45mm wall thickness makes them more susceptible to punctures than standard tubes. They are best reserved for race days or performance-focused rides where minimizing rotating mass is your priority.

No, these tubes are specifically designed for narrow road tires ranging from 18c to 25c. Using them in a wider tire can overstretch the material, significantly increasing the risk of failure.

These tubes use standard Presta valves, so any pump compatible with Presta valves will work. The 60mm valve length is generally long enough for most standard road rims, but be sure to check your rim depth before purchasing.

The rim strip is included to protect the ultra-thin tube from potential damage caused by spoke holes or sharp edges inside your rim bed. It is essential to install it to ensure the tube seats properly and to prevent premature punctures.

At 76 grams, these are significantly lighter than standard butyl tubes, which often weigh between 100 and 150 grams. You can expect to shed roughly 25 to 75 grams per wheel, which is a noticeable reduction in rotating mass for climbing and acceleration.
