I've never seen any Dopplegangers for my bikes, but they are all uncommon models -- Eddy Merckx AX, De Bernardi SL, Salsa Casseroll and a Waterford RST-22. The Casseroll is the only one that I am every likely to see as we have a local Salsa dealer, but most of the roadies around here ride carbon fiber Treks, Giants and Specialized.
