Model-level historical reference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 619 distinct legacy mountain geometries from model years 2000–2004. Only angular measurements are used because the historical reference frame size is unidentified.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 →
  • FrameCheck paint chips, vent holes and the inside of the seat tube for corrosion. Also look for dents, bent tubes and cracking around welded or brazed joints.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 →
  • 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 →

Across 10 qualifying used eBay listings, the median current asking price is $214.00 and the middle half of asks falls between $176.64–$259.33. This is active-listing evidence, not a completed-sale appraisal; condition, size, service history and local demand can change the actual price.

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

Model-year coverage: 0 of 11 qualifying asking-price listings explicitly state 2002. There are not yet three year-confirmed used listings, so the used summary is labeled as broader model-family context.

Each dot is a dated Velopedia observation built from at least three high-confidence, fixed-price or Best Offer used-bicycle listings in one consistent identity, methodology, currency and model scope. The shaded band shows the middle 50% when at least five listings supported that observation. Prices exclude shipping and tax; auctions, completed sales and appraisals are not included.

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.
