I know there will be some variables on this, but I've been trying (in my head) to piece together what the average/ standard sizes of boards/trucks/ wheels were. Shaped board eras (especially mid/late 80s)being one of the harder ones I would suppose. I've skated since 1986 so there's been a lot of changes. I know in 1994, I skated a 7.5 deck with 5.0's but can't remember what size wheels I was rolling then. Same with 1995-1997 either. I would check old catalogs, but I lost all of that stuff about 3 moves ago. I would imagine the "standard" of today to be something such as 8.25 deck, 149 (depending on brand) trucks and 54mm wheels? For an examples.
