Historical reference geometry
Geometry
This historical geometry describes the model, but the original source does not identify its frame size. Use it as a period reference, not a size-specific fit comparison.
| Measurement | Legacy reference |
|---|---|
| Top tube | 560 mm |
| Head-tube angle | 73.5° |
| Seat-tube angle | 73.5° |
| Chainstay / rear center | 405 mm |
| Wheelbase | 980 mm |
| Fork offset / rake | 40 mm |
The preserved source contains one model-level geometry set without an identified frame size.
Published drivetrain ratios
Gearing
Lower ratios provide more mechanical advantage for climbing. Higher ratios turn the rear wheel farther with each crank revolution.
The bar uses the same mechanical-ratio calculation as Compare. Wheel-dependent speed appears only when the record includes an exact ISO/ETRTO rear tire size; no tire size is assumed.
