Historical reference geometry

Geometry

Legacy reference · 6 measurements

This historical geometry describes the model, but the original source does not identify its frame size. Use it as a period reference, not a size-specific fit comparison.

MeasurementLegacy reference
Top tube590 mm
Head-tube angle71°
Seat-tube angle73°
Chainstay / rear center426 mm
Wheelbase1065 mm
Fork offset / rake38.1 mm

The preserved source contains one model-level geometry set without an identified frame size.

Published drivetrain ratios

Gearing

Chainring ÷ rear sprocket

Lower ratios provide more mechanical advantage for climbing. Higher ratios turn the rear wheel farther with each crank revolution.

Published build42/32/22T · 11–30T · 8-speed
Lowest0.73:1 Highest3.82:1 Total range521%

The bar uses the same mechanical-ratio calculation as Compare. Wheel-dependent speed appears only when the record includes an exact ISO/ETRTO rear tire size; no tire size is assumed.

Market Snapshot

Checked Sep 30, 2026 8:20 pm

Across 6 qualifying used eBay listings, the median current asking price is $265.00 and the middle half of asks falls between $252.50–$375.00. 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 8 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.
