Eisentraut is quite simply “the man”. He learned the craft of building handmade bicycles alongside Paramount maker Oscar Wastyn in Chicago. Many regard him as is the father of USA custom frame builders. Known for his “Model A” frames of the 60s and 70s, Eisentraut’s work stood heads above other US builders, who looked to Europe for their precedents.
There’s a great article from Bicycle Guide on Eisentraut below, so check it out!
Thanks to Map Cycles for digging this article up. It’d been a while since I saw it.
