Built for the Rides That Keep Going
Some cyclists ride for speed. Others ride because they enjoy being out there a little longer.
The Endurance Gravel Tube was created for the second group. It fits 700×32–45C tires and weighs 46g ±5g, making it a practical choice for riders who spend hours on gravel roads, quiet backroads and mixed terrain.
It isn't the lightest tube we make, and that's intentional. A little extra material provides added confidence when the route becomes rough or the ride stretches farther than expected.
Highlights
Made for Long Days
Built around comfort, reliability and consistent performance rather than minimum weight.
Compact by Nature
A folded TPU tube takes up very little room in your luggage or repair kit.
700×32–45C Compatibility
Suitable for many gravel, endurance and touring bicycles.
Ready for OEM Projects
Available with custom branding, packaging and private-label production.
Who Is It For?
Distance Riders
Ideal for cyclists who regularly spend several hours in the saddle.
Gravel Explorers
Suitable for everything from maintained gravel roads to rough country lanes.
Weekend Escapes
A dependable companion for riders who prefer long routes over short loops.
What Makes This Model Different?
Instead of chasing the lowest possible weight, this tube focuses on everyday usability.
The TPU construction keeps it much lighter than a traditional butyl tube, while its compact size means it disappears into a saddle bag without taking up valuable space.
For many riders, that's exactly what an endurance tube should do-stay out of the way until it's needed.
