In my foggy memory back to the late 80's I had 2 custom J P Weigle road racing bikes made by master builder Peter Weigle. I competed successfully on these steel beauties for several years; before being seduced by the the allure and light weight of Ti (Litespeed Ultimate) and carbon (Trek 5900). My Weigle's were custom fit to my long legs and short torso. No need for odd length steerer's and stems for a comfortable fit. I can't complain about my Trek addiction -- I won a lot of races over the years on them. None the less, I have fond memories of the Weigle's, and the custom, 6-9 month process of measuring my body, optimizing my positions, and coming up with a nearly perfect build. Surprisingly, after many years, custom steel bike builders are still around and flourishing. Even the race oriented crew at GCN is jumping on the custom steel bandwagon:

For more information on why custom steel refuses to fade into ancient history, here is a recent blog post from Jan Heine of Compass:

While the Swiss Cross isn't custom, the frame is well designed and manufactured. When I finally get the itch for a replacement to the Swiss Cross, I'll very likely be heading down to my neighbor Kris Henry who builds knock out gorgeous custom bikes right here in Lyndeborough NH - 5 miles from my house:
