Feels like a lot of the ace team uses risers to get em to standard Indy height
Funny that some people are so against risers, but at the end of the day, I think I would be happy to have trucks of a slightly lower height to start with that I could put on risers, than have trucks that were too tall to start with, as you couldn't really go lower once they are standard at 55mm height.
That said, I find the 55mm Indy standards perfect for the skating I do and have very thin risers on other setups with lower trucks, be it older Indys, Thunder, etc.
Oddly enough I don't have risers on the Ace 33 truck setup, but that one has pretty small wheels, compared to my other setups. The Ace 55 and 66 setups are cruisers, so have 1/4 risers and 60mm wheels.
