Frequently Asked Questions
How big a hole will it seal?
Up to 1/2 inch, per Rambo. It works continuously inside the tire, so it plugs punctures as they happen rather than after you notice them.
Which bikes does Rambo offer it for?
Rambo offers it with the Rambo Dominator UD, Hellcat 2.0 FS, Krusader 3.0, Megatron 4.0, Rebel 2.0, Revolt AWD, Roamer 2.0 and Savage 2.0.
Does it replace Tannus Armour inserts?
They do different jobs. Sealant plugs punctures once they happen; the Tannus Armour inserts add a layer between the tube and the ground to stop them.
