Wait so what are the true wheel bases for Polar?
It is a curious one, because quite a few people have said that anything listed as 14.5 is actually 14.375 but then a couple of people have said their specific version of whatever board did have a 14.5 wheelbase.
Every Polar board I have seen has had the stated wheelbase - 8.375 and 8.75 popsicles are 14.375 as well as Dane 1 14.125 and a few others I can't remember right now, but I haven't had a couple of the main ones listed as 14.5 like the normal 8.5 or 9.0 popsicles, which I think are the ones with the 14.375 wb.
I would check in person if possible any of those ones, but 14.5 or 14.375 is not a huge leap, compared to some other brands with 14.25 listed and are 14.5 or something. That said, I can definitely feel a difference in even the slight wheelbase change, so make of that what you will.
