These two pics show the 2nd and 3rd generation 3Rensho Allez bikes. The first, which came out in 1981 and was sold into 1982, did not have markings on the stay caps. It had "allez" on the top tube in a different font than the later 82-83 model, where "allez" was placed on the down tube. 1984 brought Campagnolo dropouts instead of earlier Shimano.
