First, I'm pretty sure this is a 1978 model, as opposed to 1977. There is no direct correlation to the 1980's models and the separation in years makes it a bit difficult but I'd call it upper entry level and place it between a 110 and 210. The Liberty had slack angles and a longer wheelbase so the geomtery is line with the grand touring models but a high tensile frame and heavy 29 lbs advertised weight place it among entry level models. FYI, original cost was a bout $200 US.
