Legacy reference · 5 measurements

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.

Model-level historical reference

Period context: At 70°, the head angle sits somewhat slacker than typical among mountain geometries represented in Velopedia for this period. Its 73.5° seat angle is toward the steeper end among the same-period mountain references.

Compared with 261 distinct legacy mountain geometries from model years 2003–2006. Only angular measurements are used because the historical reference frame size is unidentified.

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 →
  • FrameLook closely for dents and hairline cracks around welds, the head tube and bottom-bracket area. Cosmetic scratches matter less than a change in shape or a crack line.Inspect the frame and fork →
  • BrakesBoth brakes should stop firmly and release without rubbing. Inspect pad thickness, rotor wear and alignment, and check the cables or hoses for damage.Inspect the brakes →
  • SuspensionAsk when the fork and shock were last serviced. Check the stanchions for damage, look for oil at the seals, cycle both units through their travel and test the suspension pivots for 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 →
