Historical reference geometry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 | 560 mm |
| Head-tube angle | 71° |
| Seat-tube angle | 73.5° |
| Chainstay / rear center | 419 mm |
| Wheelbase | 1062 mm |
| Fork offset / rake | 38.1 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Model-level historical reference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 71°, the head angle sits somewhat steeper than typical among mountain geometries represented in Velopedia for this period. Its 73.5° seat angle is somewhat steeper than typical among the same-period mountain references.
Compared with 529 distinct legacy mountain geometries from model years 2001–2005. Only angular measurements are used because the historical reference frame size is unidentified.See it in periodOpen an immediate comparison with preserved 2003 mountain geometries.

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 →- FrameInspect the frame in bright light, especially around the head tube, bottom bracket, chainstays and clamped areas. Look for cracks, ripples, crushed sections or signs of a previous impact.Inspect the frame and fork →
- BrakesInspect pad condition, cable movement and the rim sidewalls or brake tracks for wear. A concave or heavily worn braking surface can mean the wheel also needs replacement.Inspect the brakes →
- SuspensionAsk when the fork was last serviced. Check the stanchions for damage, look for oil at the seals and make sure the fork moves smoothly without bushing play.Evaluate the suspension →
- DrivetrainShift through every gear under light load and measure chain wear. Confirm that the shifter, derailleur, chain and cassette belong to the same 9-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 →
