rare opportunity! principia is mostly known for handmade superstiff road frames by their special 7020 alloy, but in the 90ies they also made some very nice mtb-frames, such as the macB. characteristically are the fine welds, high quality anodization and the rear cantilever tube. just some few traces of usage, no dents. only one owner - ladys bike never been abused. last couple of years just parked. principia offered a 10 years guarantee for frame break those days :shock: I'm not totally sure about the year of this one, but since it's got a 1" steerer and a fixed derailleur hanger it has to be a very early version. smallest size (15,75"), 42cm to the end of the seat tube. more info here and here. asking price 260€ parceled europe wide.
