<< Are Alan lugged aluminum frames on topic >>
Technically, no... based upon this wording in the header oon the front page of the CR web site:
<<Dedicated to Lightweight Vintage Bicycles, circa 1900~1983. The purpose of this not-for-profit site is to encourage those interested in enjoying and preserving vintage lightweight "racing" style bicycles of the period from the early 20th century until 1983. These are primarily steel, most often "lug built", not welded, injection molded, or glued. >>
But I have been lenient on this because Alan's, although aluminum & glued, are closer to the vintage style with their lugs and looks, versus welded Cannondales and such...
