Historical reference geometry

Geometry

Legacy reference · 5 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 tube549 mm
Head-tube angle71.5°
Seat-tube angle69°
Chainstay / rear center429 mm
Wheelbase1087 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 build44/32/22T · 11–32T · 9-speed
Lowest0.69:1 Highest4.00:1 Total range582%

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.
