Kenda has made the perfect slick "fast" tire for racking. We brought these in for our kids bikes. However they are perfect for folding bikes as well. Replacing 1.75" with these light 1.2's will save you over a pound of rotating weight. Rotating weight that is far from the center of rotation drags the bike more. There is nothing as far from the center of rotation as the hub. These tires are the best way to lighten and reduce rolling resistance.

Features:

• 20" ( 406mm ) x 1.2"...don't buy these for 20" ( 451mm ) wheels, they will not fit.
• Kenda Quality
• Superlight
• Narrow to minimize rolling resistance
• Max 100psi pressure means these things will fly on the open road.
• Wire bead folds into a figure 8 for easy transport.
