Foam insert RockStop

Rockstopis a tough, highly absorbent rubberized polymer designed to fit modern ATV rims and protect them from impact in the event of a puncture.
The design of the Rockstop® places the edges of the rim against the inner sidewalls of the tire in order to diffuse the impact in the most efficient way and avoid pinching punctures. The hole design allows a good performance in terms of weight at 250 gr per insert in 29 inches.
Available for 27.5, 27.5 + and 29" rims. Compatible
with internal rim diameters from 23mm to 34mm (35mm - 45mm for 27.5+)
.
Compatible with original tubeless valves
