I just purchased this bike locally in Southern California and thought it would be straightforward to identify but I've asked around and no one seems to know.

The specs are:

  • Lugged steel (fork crown lugs match frame)
  • No serial number or builder's mark (likely repainted)
  • Mostly SSC/Zap Mavic components (suggesting French or custom build)
  • Gipiemme "patent" front and rear dropouts (124.6mm rear spacing)
  • Geometry mostly resembles an early Pinarello Prologo (not TT or track version), due to curved seat stays (only lo-pro frame I've seen with this feature!!), shape of upper seat stay tubes and their meeting point on the seat tube lug, but differs in placement of shifter boss, shape of rear drop out, and lack of builder's stamp.

  • It has a small peg/tube on the front of the upper seat tube of unknown purpose.

  • BB shell is 68mm, unknown threading (until I can remove the Phil Wood BB).

Please see attached photos. Any leads appreciated.

  • Can you get more details from the place/person from whom you bought the bike ? Looks gorgeous - would be even better with unfaded red/black splash bartape . Pink doesn't go with the frame :) – Criggie Jan 17 at 9:44
  • Damn, this bike looks like she was made of PVC, left in the sun for too long and started to melt. It's great! The headtube lugs resemble those that Gazelle (Dutch manufacturer) used for their Champion Mondial frames in the '80. The fork crown is Cinelli aero, at least it's what it looks like. The peg on the seat tube is the pump peg, common in vintage road bikes ('80s and earlier). – Mike Jan 17 at 10:45
  • Thanks for the feedback guys! The first thing I did was ask the guy I bought it from. He was selling it for a neighbor who also had no info on it. I had someone suggest it may have been stolen, repainted, and the serial filed off. However, the bike itself looks like it was untouched/unchanged since the early 90s and features a mish-mash of parts. Campy aero shifters, Phil Wood bb, Shimano 105 front derailleur, off brand steel seatpost and seat, 36h Shimano 600 front hub laced to an 18 spoke Hed front rim (who does that!?!), a specialized rear skewer, 7sp Dura Ace 7300 freewheel. – M.

  • I found it guys! The builder of this bike is Toronto-based Jo Gardin! Look up the "signature TT" or "crono" models. Canadian with Oria tubing. Woohoo! – M. Hernandez Jan 29 at 0:54
