Historical reference geometry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 | 555 mm |
| Head-tube angle | 73° |
| Seat-tube angle | 73.5° |
| Chainstay / rear center | 408 mm |

Model-level historical reference
Period context: At 73°, the head angle sits close to the middle of the group among road geometries represented in Velopedia for this period. Its 73.5° seat angle is close to the middle of the group among the same-period road references.
Compared with 334 distinct legacy road geometries from model years 2001–2005. Only angular measurements are used because the historical reference frame size is unidentified.Parts & serviceability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 →- FrameInspect the composite sections for impact or clamp damage, then check the metal joints and welds for dents or cracking. Ask about any crash history.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 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 →
