Hmmm, rather cool of HoHo to breeze in, zap the site with these sublime beauties and then never be heard from again in the twelve months since.
The Altitude is indeed a 1993, Lagoon Green with Calypso Red and original Mag21s. Rocky claimed a frame weight of 3.9lbs and their claims were usually true (Blizzard 4.4 sounds right and Equipe 4.75 is right).
It would be interesting to have HoHo's observations on the comparisons between the three bikes. In fact it would be good if RetroBike had a mtbr-style section of readers' reviews of their retro rides, with riding impressions, specifications etc.
