Frequently-Asked Questions
ANGLED TRUCK RISERS
The Seismic steering geometry is absolutely fixed and perfectly consistent - either 30-degrees (Stable-Turn) or 45-degrees (Quick-Turn). So angled risers have a totally direct and predictable effect on performance.
To quicken steering response, orient the wedge with the thin end facing the end of the deck. Usually called “wedging,” this is most commonly done with the front truck. Just remember this reduces your leverage on the springs, so you might want to loosen them or even switch to softer ones.
To slow down steering response, orient the wedge with the thick end facing the end of the deck. Usually called “dewedging,” this is most commonly done with the rear truck, especially on racing boards. Just remember this increases your leverage on the springs, so you might want to tighten them or even switch to stiffer ones.
Optimal truck mounting depends on many different variables - wheelbase, riding speed, skating style, personal preference and even body height. You’ll need to experiment to see what works best for you.
WHEEL RUB
Before skating any new setup for the first time, you should always test on carpet for the possibility of wheel rub.
Wheel rub is a “systems issue,” related to the total deck-wheel-truck combination. The manufacturers of individual components can’t be held responsible for ensuring that you won’t get wheel rub when combining their product with parts from other companies.
The axle height and tilt range of Seismic trucks were very carefully engineered to suit most people most of the time. If you’re experiencing wheel rub, your best solution is to use more riser under your trucks, and/or smaller wheels, and/or a deck with wheel wells or wheel cutouts.
If your bodyweight is on the high side, another issue to consider is torsional deck flexion. Under the weight of heavy skaters, decks twist more than normal. This means that the deck actually flexes toward the wheels during turns (especially at the nose), making wheel bite even more likely. Extra-large skaters should consider choosing stiffer, thicker decks, possibly with concave, to gain more torsional stiffness.
