This Koga-Miyata FullPro-S frame is showing many aero influences and dates from before the aero era took off. Serial# tells me it is from 1977. Rare, not present in any catalogue and not much known of. Maybe it is even a one off for display on bikeshows, but without any doubt it is at least part of a very small run.
The full bike came with several drilled out parts for the purpose to save weight. The 3T stem had drillings in the shaft, a drilling from the back through the actual stem and there was even excess material shaved off the bolt head flange...
The aero features of the frame:
- Aero crown
- Shifters on top downtube
- Internal routing for brake AND gear cables. Rear brake cables exits through seatpost!
- Low profile seatcluster, milled stainless binder bolt
- Recessed brake calliper mounting bolts, milled stainless steel
- 63mm wide bottom bracket shell
exit gear cable front
exit gear cable rear
I will be rebuilding it with early Dura-Ace groupset including Crane mech.
In 1981 Koga introduced the FullPro-L with several aero influences. A year later a completely fillet brazed FullPro-A with drop shape tubing was introduced. Both FP-L and FP-A were equipped with the full Dura-Ace AX groupset.
