Eclipse Gravel GT Inner Tube | 28" | 30-45 mm

Eclipse GT – Inner Tube with Thread and Nut

A gravel inner tube for long days on rough roads – featuring a thicker TPU wall than the Performance line for added puncture protection exactly where it matters most. Made in Germany with a patented all-aluminum valve and a patented end-to-end welding process.

Features of the Eclipse Gravel GT Bicycle Tube - Includes thread and nut

Thicker sidewall for greater confidence on rough terrain.

The GT uses a thicker TPU than the Performance gravel tube. Sharp-edged rocks, broken asphalt, and unpredictable terrain—the GT is built for surfaces where you can’t freely choose your line.

65–69 g, depending on valve length.

That’s still about 60% lighter than a standard butyl gravel inner tube—a significant weight savings you’ll feel both when accelerating and when carrying a spare inner tube in your frame or jersey pocket.

Pressure-stable.

TPU maintains air pressure more consistently than butyl. You’ll need to top up the air less often, and the ride feel stays consistent even after a long day on the saddle.

Patented all-aluminum valve with removable valve core.

If the valve core ever comes loose or develops a leak, it can be repaired in 60 seconds using a valve tool. No new inner tube required.

Fully 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 small.

Fits in a jersey pocket, frame bag, or saddle bag. An important detail when you’re hours away from the nearest bike shop and need to carry your own insurance.

100% recyclable.

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