I've skated ace 55s and Indy 169s and the 55s definitely stick out more.� I haven't really gotten the measuring tape and the magnifying glass out to measure that carefully but the difference is obvious when riding around.� Every company wants to measure their trucks different and makes slightly different sizes for some reason.� No matter how well those polar bear trucks are made it'd be fucked to look down at my setup and see longboard trucks every time.� You post on silverfish?
Hmm, maybe there is some variance among different lots of Aces, I know they went through a few hiccups in the manufacturing because people were posting picks of weak trucks with bent axles. Maybe it has to do with the threaded part of the axles or what width wheels you were skating? Who knows. I will maybe give them a shot at some point. I know there is one blogger that actually went through the trouble of measuring around 30 pairs of trucks with a pair of calipers.
The Polar Bears are not longboard trucks. Other than the double drilled baseplate, there is nothing "longboardy" about them other than that they're made by a longboard company out of Canada that decided to make a regular truck. They do have taller than normal bottom bushings compared to most of today's trucks but that's not any different than a lot of trucks that skaters were riding in the 80s. They don't feel weird or super squirrelly/carvy like longboard type trucks either. When you're ~200lbs or more, you appreciate things that are durable. I actually corresponded by email with one of the guys that designed the Polar Bears...he mentioned that they were trying to make a durable truck that was good for skating park transitions, pools, etc. They weren't trying to make a longboard truck. I guess Ace was trying to do the same thing with their design throwback to Stage 3 Indys?
I do post of Silverfish occasionally, but only in the Park section. I don't even own a longboard, nor have I ever ridden one. I like the park forum because they're some knowledgeable older dudes that hang around there. As a 90s street skater trying to get back into it and learn more transition oriented skating this time around, there is some worthwhile info over there.
