Historical reference geometry

Geometry

Legacy reference · 6 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.

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Model-level historical reference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 70°, the head angle sits toward the slacker end among mountain geometries represented in Velopedia for this period. Its 73° seat angle is close to the middle of the group 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 Only angular measurements are used because the historical reference frame size is unidentified.

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 →
  • 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 8-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 →

Market Snapshot

Across 4 qualifying used eBay listings, the median current asking price is $347.50. The sample is large enough for a median but not a stable price band, so Velopedia does not publish the raw low and high.

Evidence standard Fixed-price and Best Offer item prices only Shipping and tax excluded Active asks, not completed sales

Model-year coverage: 0 of 17 qualifying asking-price listings explicitly state 2003. There are not yet three year-confirmed used listings, so the used summary is labeled as broader model-family context.

Listings shown have not passed their eBay-supplied end time. Velopedia rechecks matched bicycles on a protected weekly cycle; availability can still change between checks. Price calculations use active fixed-price and Best Offer item prices before shipping and tax. Auction bids, auction-only prices, classified ads, lower-confidence Review candidates and ended listings are excluded. These observations are not completed-sale prices, a certified appraisal or a guarantee of value.

Specifications are presented as a reference. Components may vary by market, size, production run, or later manufacturer revisions.
