I am curious about the manufacturing origin of this bike. I know most Ascents were partially built by Toyo Japan and the stays and finish work were done by Tom in Palo Alto. I’ve read that there were a few TIG welded frames either made in Tom’s shop or by other local frame builders. It seems Toyo frames had a fairly consistent serial number format Letter – Number – Letter – followed by 4-5 numeric digits. A few, like mine, have 3 numerals hand stamped under the bottom bracket. The other difference I have noticed is in the seat tube lug. All of the longer serial format bikes have a pointed lug and the 3 digit bikes use a straight cut lug. That is one clue to these bikes being built in different places. I would love to know if anybody has more information on what might be going on here. I e-mailed Ritchey’s contact us address through their website and got a fairly generic answer (Toyo tig’d the front triangles in Japan and Tom finished them in his shop).
Is there a URL where people can read or see more about your bike?
