If you want to learn something, you have to be first and foremost willing to practice today almost forgotten activity - reading.
In theory, everything is compatible with everything but in practise it takes a bit of help. And that holds true even for the parts from the same brand.
1. What headset should I get for my deck with integrated vs. standard headtube?
You need to get an integrated threadless headset for a deck with integrated headtube. However, since the integrated headset is a subset of a standard headset, you can also buy a standard threadless headset and throw away the parts that you dont need. But why would you do that?
2. What headset should I get for my scooter using threaded fork (entry-level scooters)?
You need to buy a threaded headset. These can be had at any bikeshop and their retail price should not exceed 10 €.
You can also use a standard threadless headset. In this case, it is necessary to use the original nut that sits on the headset. For more information on this watch the following video https://www.youtube.com/watch?v=h0CgOey8lxI&list=PL625D416DF2978025&index=12
Cost-wise this is not the best solution. Chances are the market value of your scooter is the same as is the price of a new threadless headset.
3. Wheel diameter vs. existing fork and deck
When upgrading to bigger wheels, make sure your existing setup = fork + deck + brake is compatible with those wheels.
Visual check and some common sense should be enough. It is no rocket science after all.
4. What clamp should I get considering the outer diameter of my handlebar?
Two different outer diameters (handlebars): 31.8 mm and 34.9 mm.
When getting a new clamp, make sure you are buying a clamp with the correct inner diameter. For a 31,8 mm handlebar you need to get a clamp with 31,8 mm of inner diameter.
Most clamps today come with a steel shim / insert. This allows the clamps to be used with both regular (31,8 mm) and oversized / aluminium (34,9 mm) handlebars. The shim would only be used on handlebars with 31,8 mm of inner diameter.
5. What brake should I get for my existing deck?
Brakes are a headache at times. There is nothing like a universal brake. If you can not find the original brake for your deck in the after market (some brands do sell the original brakes, some others do not) you´d better call or send an email. There will always be a solution to your problem.
6. What SCS should I get for my existing handlebar
The lines bellow are for those customers who are upgrading to the SCS from another compression system. First of all, you need to realize what the specification of your existing handlebar is. Outer diameter of 31.8 or 34.9 mm? Slitted or non-slitted? Aluminium or steel?
a) Most of today's SCSs are compatible with both diameters. However, you´d better verify this before committing to purchase.
b) The SCS shim will ONLY be used on handlebars with outer diameter of 31.8 mm.
c) If you run an aluminium handlebar, reconsider the purchase of SCS. It might be a waste of money. It is namely the aluminium handlebars that work just fine with the ICS compression system.
d) The handlebars used in combination with SCS must not have a slit. There are two ways of removing the slit:
- Cut the slit off
- Use a steel insert. The later will add 40 mm to your handlebar height.
What to keep in mind
a) Using the SCS positions your handlebar higher by about 4 cm.
b) This means that when you remove the slit (the length of which is usually 4 cm) and use the SCS, you do not lose any of the original height of your handlebar
c) However, if you do not cut the slit off and use the steel insert / shim instead you add additional 40 mm to your bar height.
7. Can I run the HIC compression system with my existing handlebar
It's simple. You can use the HIC compression system upon the following conditions: a) You have either the CrMo or titanium handlebar with inner diameter of 31.8 mm and outer diameter of 34.9 mm. b) Your handlebar is slitted.
No other handlebars would work with the HIC compression system.
How does the HIC system look like? http://https://www.gizmania.ee//freestyle-scooter-parts/kompresni-systemy/hic-kubars.html
8. What handlebar would fit my existing compression system?
See the points 6 and 7.
My existing compression system: ICS, threaded fork, IHC, SCS or HIC?
My existing handlebar: Outer diameter, inner diameter, slit?
If you are buying a new handlebar that needs to be compatible with your existing compression system, it's easy. You know what the specification of your existing handlebar is (outer diameter, inner diameter, material, slit). What are you waiting for? Get out and get any handlebar of the same specifications.
Note: If you plan on switching to the SCS or HIC compression system, refer to the points 6 and 7.
9. What fork should I get?
When selecting a new fork you need to pay attention to what type of compression system you are currently using. If you run the SCS you will not buy an ICS fork, of course.
Be aware of the height of the deck headtube as this may vary by manufacturer.
Decks with short headtubes (for example, MGP decks) do not work well with some of the SCS forks that have long tubes. This problem can be resolved by using spacers, see https://www.gizmania.ee/freestyle-scooter-parts/headsets/headset-spacers.html
The regular height of the non-integrated headtube is about 90 mm (105 mm including headset). The regular height of the integrated headtube is about 100 mm (105 mm including headset). Most forks are designed to fit this height. At any other headtube height, you need to do some *research* on compatibility before committing to purchase.
10. Threaded forks and pegs
We certainly do not recommend using pegs on a scooter fitted with a threaded fork.
Threaded forks are designed for entry-level scooters used by beginners and therefore the fork frame is not as sturdy as it is in case of threadless forks. Threaded forks fitted with pegs would bend or snap soon.
Beginners are advised not to use pegs anyway.
