I bought this 1970s Rabasa Derbi Spanish frame and converted it to a fixed gear, retaining some of the original parts and adding a modern touch with new wheels, cranks and seat. The original parts include, the alloy seat stem, head set and bars (Beleri France), and Olympic centre pull brakes. The wheel set is Star Circle deep V and I’m running a 52/17 ratio. the cranks are lasco, and the seat is a Selle Italis SLR.

I hardly know anything about the frame, so if anyone can tell me about it I’d be really appreciative!
