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Model-level historical reference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 steeper end 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 1565 distinct legacy mountain geometries from model years 1995–1999. Only angular measurements are used because the historical reference frame size is unidentified.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 →
  • FrameInspect the complete frame and fork in bright light for cracks, dents, distortion, corrosion, impact marks, suspicious paint differences or signs of repair. Check the head tube, bottom-bracket area, dropouts, joints and clamped surfaces especially closely.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 →
  • 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 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 →
