Features of the Eclipse Performance Gravel Bike Tube - Includes thread and nut

51–53 g, depending on valve length.

About 70% lighter than a standard butyl gravel inner tube—a difference you’ll feel when accelerating on undulating terrain and in your bag when carrying a spare.

Holds pressure on washboard and gravel.

TPU doesn’t creep at gravel pressures like butyl does. Stable ride feel hour after hour, no gradual sagging halfway through the ride.

Patented aluminum valve with removable insert.

If the valve insert ever loosens or leaks—60 seconds and a valve tool are all it takes to fix it. No new inner tube needed. Compatible with standard extensions.

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.

Clik Valve compatible.

Works with the Eclipse Clik Valve conversion kit (sold separately) for one-handed pump connections on the go.

Packs down to almost nothing.

Smaller than a butyl spare tube. Fits in a top tube bag, frame bag, or jersey pocket without taking up the space you’d rather use for snacks.

100% recyclable.

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