Fly Ruben LIGERA Folding Tire 1.90 - Black
After the original Ruben tyre changed how standard bead tyres were made, FLY decided to release a kevlar version.
The two classic treads and a newer, updated version were put out.
The LIGERA version of Ruben's signature tread is very similar to the original, but, they cut out some material for less weight and more grip.
Good on any surface.
