Reliable pressure retention - thanks to seam-free construction

Fewer slow leaks between rides, meaning less frequent top-ups and more confidence on long trail days.

Faster inflation and easier roadside repairs, compatible with most standard tyre pumps and compressors.
Broad 21-inch compatibility - with multi-size fitment
Fitment includes 2.75/3.00-21 as well as 80/90-21, 90/90-21 and 100/80-21 sizes, matching common front tyre dimensions. The specification targets a range of popular off-road tyre profiles for 21-inch rims.
