Historical reference geometry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 angle70°
Seat-tube angle73°
Chainstay / rear center436 mm
Wheelbase1071 mm
Fork offset / rake42 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.

Published build42/34/24T · 11–28T · 7-speed
Lowest0.86:1 Highest3.82:1 Total range445%

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.
