For anyone looking for more info on the cranks, they are a 2/3 year old model from FSA (new in box) NOS I guess but not exactly a classic part, very very beefy, along the same kinda lines as Profile SS cranks (much beefier version of profile race), comes with 19mm hollow axle, all bearings/cups for mid or USA BB installation, and is compatible with Euro BB's for use on mtb/euro BB bmxes, you could use them on fixed if you want, but a bit too long for fixed use IMO, would be fine for an SS polo bike though I reckon.
