Ultra · Performance · GT (Gran Turismo)
Eclipse makes three lines of TPU inner tubes. Same patented valve, same patented welding process, same German manufacturing and individual QC testing. What changes is the wall thickness — and with it, the balance between weight and durability.
Wall thickness and road weight
Thinner wall = lighter. Thicker wall = more puncture protection.
Same valve, same welding, same testing. Pick the wall thickness that fits your riding.
The competition tube
The thinnest TPU wall in the Eclipse range — for riders who want every possible gram advantage.

The everyday tube
The centre of the Eclipse range: the weight savings and ride quality of TPU without compromising on real-world durability.
The widest size range: from road to MTB, BMX and Brompton

The durable tube
The thickest TPU wall in the range — built for riders who measure their days in hours and kilometres, not sprints.

Weight depends on size and valve length.
Ultra — The competition tube
Good to know: The Ultra's thinner wall trades some puncture resistance for the weight saving. If you're riding rough roads, mixed surfaces, or in conditions where flats are likely, consider the Performance or GT instead. The Ultra is a purpose-built racing tube — it excels when speed and weight are the priority.
Performance — The everyday tube
Good to know: It's the tube we recommend to anyone trying TPU for the first time. The weight penalty versus Ultra is minimal in real-world riding, and the durability gain is meaningful.
GT (Gran Turismo) — The durable tube
Good to know: If you're unsure between Performance and GT, ask yourself: would a flat on this ride be an inconvenience or a serious problem? If the answer is "serious problem", GT is the right choice.
Every Eclipse tube — Ultra, Performance and GT — is built on the same foundation.
With removable core. Compatible with standard extenders. A loose core is a 60-second fix, not a new tube.
Eliminates the overlap seam — historically the most common failure point in TPU tubes.
Water-immersion test and 24-hour pressure test before shipping. Not batch sampling. Every single one.
Every tube is manufactured in Germany: welded, valve fitted, individually tested and packaged in our own facility.
TPU is thermoplastic and can be reprocessed; the recycled material can be used to produce new tubes.
