As with a bicycle's tubing, a skate's frame material largely determines its feel. Less expensive skate frames are made of plastic or nylon, both of which provide a smoother ride. Plastic is particularly adept at damping vibrations, but it loses its resilience on bumpy roads, ergo less control. A skate's chassis length is just as important as its construction. A shorter wheelbase facilitates acceleration and maneuverability.
Wheels determine how the pavement feels underfoot.
Harder, or denser, wheels roll faster on smooth surfaces and are highly durable. Soft wheels offer a smoother, more comfortable ride on rough ground. Hardness is indicated by a durometer rating. The harder the wheel, the higher the durometer number. Most skates in this review come standard with 78A-durometer wheels.
