Hartex Action Gumwall is a straightforward fat bike tyre for riders who need large casing volume at a sensible price. The 26x4.00 / 100-559 size gives the footprint expected from a fat bike setup, helping the bike float on sand, snow and loose ground. Its small knobs keep it adaptable, making it suitable for replacement builds, utility fat bikes and casual off-road use rather than a narrow racing role.
