The frameset was acquired from Jay's Pedal Power. Getting him to sell this was pretty tough, but well worth it. Full build details below:
Frameset: 57cm GT Edge
Wheelset: Handbuilt White Industry T11 hubs laced to HED Belgiums
Groupset: Campagnolo Chorus 11 Speed
Saddle: Brooks Cambium C13
This frame is a '89 564 built by Schwinn. Many features of this frame were inspired by Gary Klien frames, such as the wishbone seat stay and strange chain stay cable guide. One very unique feature however, is the lack of a seatpost clamp. This frame was built to be paired with a Suntour quill seatpost, a very tough item to find.
