||These wheels are excellent on my SFR Street 86 skates, although I did put 2 x 3mm washers between the truck and the plate on each truck to give more clearance, and so the combination has formed a really good outdoor quad skate combination. As my quad skates are blue, the wheels fit in so well they look stock.
These wheels are 70mm x 44mm x 78a wheels are really good for outdoor street quad skate use. So far, due to weather, I have only used them outside in a park called Town Lawns in Market Drayton, England. I have also used them on our local indoor roller rink too. However, I will use them more outside from March onwards, which I am so looking forwards to.
