Historical reference geometry
Geometry
Historical model-level geometry recovered from Velopedia’s original archive database. The source does not identify which listed frame size this reference describes, so fit interpretation is intentionally limited and no size-normalized Archive Context is generated.
| Measurement | Legacy reference |
|---|---|
| Top tube | 550 mm |
| Head-tube angle | 72° |
| Seat-tube angle | 73° |
| Chainstay / rear center | 450 mm |
| Wheelbase | 1037 mm |
| Fork offset / rake | 50 mm |
Geometry source: Historical archive database — model-level reference geometry. The historical source provides one model-level geometry set and does not identify the corresponding frame size.

Model-level historical reference
Period context: At 72°, the head angle sits toward the slacker end among road geometries represented in Velopedia for this period. Its 73° seat angle is somewhat more relaxed than typical among the same-period road references.
Compared with 496 distinct legacy road geometries from model years 1996–2000. Only angular measurements are used because the historical reference frame size is unidentified.Parts & serviceability

Used-bike inspection
If you’re buying this bike used
Before any test ride: both brakes should stop the bike firmly and release cleanly; both wheels should run true and be securely attached; tires should have no casing damage; and the headset, handlebar, stem, cranks and pedals should have no looseness or play.
Follow the full used-bike inspection order →- FrameCheck paint chips, vent holes and the inside of the seat tube for corrosion. Also look for dents, bent tubes and cracking around welded or brazed joints.Inspect the frame and fork →
- BrakesTest each brake separately and confirm it stops firmly and releases cleanly. Inspect the pads and braking surfaces for wear or contamination, and check the cables or hoses for damage.Inspect the brakes →
- DrivetrainShift through every gear under light load and measure chain wear. Confirm that the shifter, derailleur, chain and cassette belong to the same 7-speed system.Check drivetrain wear →
- Wheels & tiresSpin both wheels and watch the rims for side-to-side or vertical movement. Check for dents, cracks, loose or uneven spokes and hub play, then inspect both tire casings for cuts, cracking or exposed threads.Check wheels and tires →
