GET TO KNOW YOUR FREESTYLE SCOOTER
Here you will find the terminology relating to the freestyle scootering universe.
The platform for placing the feet. The deck can be extruded or machined from solid metal. The distinction lies mainly in design and geometry, and makes little difference to the sturdiness of the deck. Extruded decks generally feature a down tube or head tube welded to them at one end. The most important consideration when selecting a deck is its weight and weight distribution.
This is the scooter's handlebar, and pivots 360°. The bar can be steel, aluminium or chromoly steel. Steel T-bars are more solid, but heavier. Most freestyle scooters have an aluminium or chromoly steel T-bar to make them more lightweight. Weighing the same, chromoly steel is the strongest alloy. A one-piece T-bar is often chosen by freestyle scooter designers. Unlike T-bars joined together with clamps, they are a single piece, welded together. This makes the scooter lighter and prevents parts coming loose.
Holds the front wheel in place and pivots 360°. Forks can be extruded or machined from solid metal. Freestyle scooters general have an aluminium fork to keep them light. Some scooters, like the MF1.8, have steel forks, which are heavier but also stronger when trying out tricks for the first time.
This connects the deck to the T-bar, allowing the scooter to steer. The headset can be threaded, thread less, semi-integrated or non-integrated. Cartridge headsets can be threaded, thread less, semi-integrated or non-integrated.
These help the wheels and the fork to turn for longer and more quickly on their axle. Bearings are classified by ABEC (the Annular Bearing Engineers' Committee). The higher the ABEC rating, the quicker the bearing rotates, but also the more fragile it is.
A collar securing the T-Bar to the fork with the aid of a self-locking screw. It can be made of between one and four screws.
A hard polyurethane resin wheel, allowing the scooter to roll. Most wheels are extruded and then re-worked. The hub can be solid or with holes. It can be aluminium or nylon. Nylon (plastic) wheels are by definition less resistant than their lighter aluminium counterparts. Aero Core (Madd-mark) wheels are more suited to expert scooter-riders who make fewer errors when landing or performing tricks and therefore gain from their increased lightness. The resin around the hub is polyurethane (PU). Its durability is measured by its "A" rating. (85A for Oxelo wheels; 88A for Eagle wheels, etc...).
Pegs are metallic accessories attached to the wheels' axles, allowing the rider to perform grinds.
This is the system for tightening the headset. There are several kinds of compression system. The compression system allows the rider to control the headset throughout his or her ride. There are three types of compression system with thread less, semi-integrated and non-integrated headsets: the SCS, the HIC, and the ICS (see picture). To check the headset of a scooter with an SCS or HIC compression system, it is necessary to remove the T-bar. If the scooter has an ICS compression system, then the wheel must be removed.
