The FR UFR Street frames are frames of the brand FR and have been designed by the frame brand Oysi.
They are designed to ride flat, using 4x60mm wheels.
It offers a generous, refined out-of-the-box groove centered between a middle wheel split of 115mm. It provides a lower ride height within a compact form and slim profile.
There are three wheel bases : 275mm, 260mm and 241mm.
There are three colours too: white, black and red (in fact magenta).
The maximum diameter of the two inner wheels is 60mm. So that is of course the maximum wheel diameter when riding flat.
But when skating anti-rocker, it is a different story.
- The outer wheels can have a maximum 62mm diameter.
- When using the FR UFR soulplates (as found for instance on the FR UFR Street Diako Diaby) you can take outer wheels with a larger diameter because of the outer wheel recess in this soulplate.
- With the 241 mm wheel base, the max. diameter of the outer wheels is 65 mm.
- With the 260 and 275 mm wheel bases, the max. diameter of the outer wheels is 72 mm.
Which wheel base should you choose?
* for sizes EU 34-39: take wheel base 241mm.
* for sizes EU 40-42: take wheel base 260mm.
* for sizes EU 43-47: take wheel base 275mm.
