Historical reference geometry

Geometry

Legacy reference · 6 measurements

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.

MeasurementLegacy reference
Top tube565 mm
Head-tube angle73°
Seat-tube angle73°
Chainstay / rear center410 mm
Wheelbase990 mm
Fork offset / rake40 mm

The preserved source contains one model-level geometry set without an identified frame size.

Published drivetrain ratios

Gearing

Chainring ÷ rear sprocket

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.
