It’s everywhere on our site, but what is durometer?
Durometer is the scientific word for hardness in elastomers. It’s measured from 0 to 100, with 100 being the hardest.* We consider 90-97.5a to be hard, 80-88a to be Medium hard, 70-78a to be medium soft, and 60-68a to be soft. Our softest bushings can be “squished” by hand and feel a bit like a gummy bear (not as tasty though - do not try to eat our bushings).
We have the widest range of durometers of any bushing manufacturer because different disciplines and riders want different hardnesses. We started RipTide because when Jeremy was young, he wasn’t heavy enough to turn his skateboard and it wasn’t fun for him. Going down to 60a gave him and a lot of other young riders the ability to turn and control their boards.
Along that line, lighter riders typically want softer (lower durometer) bushings because they take less weight to turn, and heavier riders typically want harder (higher durometer) bushings. We recommend you look at our weight charts to give you an idea of what each durometer will feel like depending on your weight, especially when combined with different shape combos.
A note on mixing durometer: It is usually not necessary to mix durometer within the same truck because the different duros will even each other out. For example, if you try an 95a bottom bushing and a 85a top bushing, it will feel like you’re riding 90’s. So just order 90’s.
