If you purchased a kit, you might have wandered about the Wedge Riser and their function.
Here we will try to provide you with more insight into what they are for and if you should use them or not.
The wedge risers serve 2 primary functions:
- Pre-load carbon baseplate against the belly of the board: the carbon baseplate should ideally be as flush as possible with the underside of the board. As the carbon baseplate bends where it transition from the risers to the board, it acts as a spring. This additional tension we get will allow a wider array of board shapes to work with the Unlimited kit without making thumping sounds as the board flexes.
- Reduces rear truck angle (setup as a top mount): the wedge risers will effectively reduce the rear truck angle and make the board more stable and less turny. This is a desired effect for the higher speed riding that is done with electric skateboards, as the board will be more stable in a straight line and through high speed turns. Downhill type trucks already come with a reduced angle for this same purpose.
You might be thinking then that you MUST use the risers, the short answer is NOT ALWAYS! Depending on the board you choose, there might not be a need for the additional preload to secure the carbon plate. You might also want more turny trucks for your style of riding.
So what happens if you don't want to install the risers but are getting thumping sounds or the plate is not fully flush with the bottom of the board (due to shape, flex or other)? We've included a threaded insert in the middle of the carbon plate right below the batteries to be used with either of the #10-32 standard skate thread supplied bolts. We included a 3/4" and 5/8" to be used depending on board thickness, it should NOT protrude over the carbon flat surface.
You will need to drill a hole through your board to install it. Using the carbon plate as a template, mark the location and then drill with a #7 (13/64") or 5mm drill bit. Remember, measure twice and drill once!
Finally, use one of the supplied bolts and tighten the carbon plate agains the board (don't overdo it as you might damage the foam that acts as vibration damper)
