I think it will be a very nice ride for somebody a little taller than me, it's just a bit too big at 60cm for me to keep.
All were HECHO EN MEXICO ! I'm sure the Fraysee & Raysport were both "house brands" built for US shops, and they're made of 531. Windsor used Columbus SL/SP tubes. BTW, if your frame has the serial# stamped in the side of the seat lug, it's a most likely a Windsor. Windsors used the 26.8 seatpost on early models, and 27.2 on later ones.
