35–40 g, depending on valve length.

That’s about 70% less than a standard butyl tube—a difference you’ll feel when accelerating and in your jersey pocket when you’re carrying a spare tube.

Holds pressure like it means business.

TPU doesn’t “creep” at high air pressure like butyl does. You get a stable, consistent ride feel over long distances—less frequent re-inflation, no gradual deflation while riding. No sealant, no clogged valves, no Tuesday ritual.

Patented aluminum valve with removable valve core.

If the valve core ever loosens or leaks—it’s fixed in 60 seconds with a valve tool. No new inner tube needed. The valve is also compatible with standard extensions for high-profile rims.

Seamlessly welded, not glued.

Eclipse’s patented welding process eliminates the seam—historically the most common weak point in TPU inner tubes. Backed by strict in-house quality controls before anything is shipped.

Packs down extremely small.

Smaller than a butyl spare tube. Fits in any jersey pocket, saddle bag, or lunchbox without having to rearrange everything else.

100% recyclable.

When it finally wears out, it won’t end up in a landfill.
