===Flat setup===
A flat setup is the most common setup used on inline skates. Almost all non-aggressive inline skates are sold with a flat wheel setup. Flat means that all the wheels touch the ground at the same time when resting on flat ground. Flat setups are not the most maneuverable but what they lack in maneuverability they make up for in speed. Flat setups tend to be the fastest setups, compared to setups such as the Hi-Lo or anti-rocker. The presence of two middle wheels matching the diametrical size of the rest increases contact points with any surface.  They also minimize the rate at which the skater's loading weight deforms the wheels. This minimizes the wheel's footprint thereby minimizing rolling resistance. [[Inline speed skating|Speed skaters]] and marathon skaters normally use flat setups. This setup also allows for a [[Powerslide (inline skating)|powerslide]], an advanced braking method.

Aggressive skates are sometimes sold with flat setups, but with a small space in the middle for grinding. With aggressive skates, the flat setup obviously leads to better control on the ground when either accelerating on a push or decelerating on a drag because of increased traction. It also grants a faster speed, translating to faster grinds, more powerful pumps in a skate ramp, and higher heights ('airs') off the edge of a vert ramp. Indeed, flat setups are quick save for the likelihood that they will be heavier and the two standard central wheels tend to 'bite' when grinding. Similar to skateboarding in certain respects, 'biting' is a common hindrance during grinding whereby friction between the wheel(s) and surface it comes into contact causes the wheel(s) then entire boot to suddenly reach a halt and the momentum throws the aggressive inline skater off the rail or ledge. Again, the aspect of wheel profile is key here. A harder wheel on a flat setup will slide and 'bite' less than a softer wheel. Likewise an elliptical profile (Undercover's Dustin Werbeski 'super bullet' wheels for example) possesses less surface area hence it will not bite as much either. Adjusting to a flat setup can even out shock when landing jumps. In doing so, an inline skater's hardware like wheels, bearings, axles and the frame itself are twice as much to be spared damage.

It is worth noting that having a flat setup is just one factor in a fast skate setup. A long frame, low resistance bearings, and good technique all contribute greatly to a skater's speed.
