gotrax g4
The media could not be loaded. if you grew up fixing your own bikes then you wont have any trouble. i boiled each tire 1 at a time for 20mins then quicky install when its hot af so wear work gloves. took me 1 to 2 mins to get the tires on. didnt even use the plie bar that thing was useless n was scratching up the rim.the ride feels fine just stiffer like you can feel the cracks you run away but your get use to it. ill gave it like 7 outta 10

Cheap product
Both of the tubes lasted about 2 weeks they both failed at the same spot the seam where the valve stem is attached.
