Me and Greg created a list of some scooter terms that needed to be clarified and/or modernized. If you have any more stuff that is commonly misunderstood, just post it and I'll edit it in.
BROKEN WHEELS
Dehubbing Ã?¢ââ??‰â?¬Å? A dehubbed wheel is a wheel where the glue of the wheel has failed. There is little to no urethane left on the core of a dehubbed wheel. The urethane has completely separated from the core. If the urethane has split, then it has NOT dehubbed, itÃ?¢ââ??‰â??¢s chunked, broken, whatever.
WELDED BARS
Two-Piece Bars Ã?¢ââ??‰â?¬Å? These are also known as one-piece bars, but that is NOT accurate. The basic shape of welded bars is two tubes welded as a Ã?¢ââ??¬Ã?â??TÃ?¢ââ??¬Ã? shape. These are known as two-piece bars. This is because there are two tubes, not one. Bars with gussets such as Wee v3s and Rad v4s are known as gusseted two-pieces.
Four-Piece Bars Ã?¢ââ??‰â?¬Å? Protos are the only four-piece bars available right now. This design consists of four distinct tubes. One vertical, one horizontal, and two diagonal, creating a Ã?¢ââ??¬Ã?â??YÃ?¢ââ??¬Ã? shaped handlebar.
FORKS
Threaded Ã?¢ââ??‰â?¬Å? Threaded forks consist of a forktube that has been threaded on the top. The reason to this is to be able to tighten the headset with a threaded nut that presses against the bearings. Stock razor forks are threaded.
Threadless Ã?¢ââ??‰â?¬Å? Threadless forks consist of a forktube without threads. For these forks to function properly you need a separate compression system, such as the SR compression system requiring a bolt and starnut, and a threadless headset. This compression system pulls the bars against the threadless top cap which presses against the headset bearings, keeping them tight and smooth.
HEADSETS
Unsealed Ã?¢ââ??‰â?¬Å? Unsealed headsets are headsets in which the bearings are NOT sealed. Unsealed bearings are found in stock razor headsets and many aftermarket bmx headsets as well. You can tell if they are unsealed if when you disassemble the headset you can see the ball bearings clipped inside the bearing race. These headsets might be slightly faster but they require more maintenance and cleaning and are not as smooth.
Sealed Ã?¢ââ??‰â?¬Å? Sealed headsets are headsets in which the bearings are sealed. Sealed bearings are found in most aftermarket bmx headsets. You can tell if they are sealed if when you disassemble the headset, the ball bearings are not visible because they are enclosed in a cartridge cage. These are generally slower than unsealed, but are smoother, stronger, and require much less maintenance.
Threaded Ã?¢ââ??‰â?¬Å? A threaded headset includes a top cap that has threads on the inside. These are found in stock razor headsets. These require a threaded fork to function properly.
Threadless Ã?¢ââ??‰â?¬Å? A threadless headset includes a top cap without threads on the inside. These require a threadless fork to function properly.
MATERIALS
Aluminum Ã?¢ââ??‰â?¬Å? Aluminum is a lightweight material with a low density. Aluminum is used in razor decks to keep the weight down and the machining cheap. It is not a sufficient material for aftermarket bars and forks unless thick walled tubing is used.
4130 Chromoly Ã?¢ââ??‰â?¬Å? 4130 chromoly is a steel alloy with a much higher density than that of aluminum. It has a great strength to weight ratio which makes it a perfect candidate for bars and forks. It is much more expensive to machine than aluminum so chromoly decks are very uneconomical.
Titanium Ã?¢ââ??‰â?¬Å? Titanium is in between aluminum and chormoly. It is heavier than aluminum, but weaker than chromoly. It is extremely expensive to weld and machine making it extremely uneconomical for any parts. IT SUCKS FOR SCOOTERS.
SCOOTER FLIPS
Inward Ã?¢ââ??‰â?¬Å? Inward scooter flips are NOT front scooter flips. In fact, an inward scooter flip is a category of scooter flips. Inward means that the scooter flips in front of your feet. That means that if you ride goofy, you flip the scooter on your left. If you ride regular, you flip the scooter on your right. If you ride ski, it depends how you land. If you land in skiÃ?¢ââ??¬Ã?¦youÃ?¢ââ??‰â??¢re badass. This also applies to back and front briflips.
Outward Ã?¢ââ??‰â?¬Å? Outward scooter flips clarify when the scooter flips behind your feet. If you ride goofy, you flip the scooter to your right. If you ride regular, you flip the scooter to your left. This also applies to back and front briflips.
NOSEMANUAL VARIATIONS
Nosemanuals Ã?¢ââ??‰â?¬Å? Nosemanuals consist of balancing on your front wheel with both feet on the deck.
Hang-5 Ã?¢ââ??‰â?¬Å? Hang 5s consist of balancing on your fronwheel with one foot on the folding-mech/headtube and one foot dangling to help counter-balance your weight.
One-Footed Nosemanual Ã?¢ââ??‰â?¬Å? A one-footed nosemanual consists of balancing on your front wheel with one foot on the deck and one foot dangling.
