Velopedia analysis
What the specifications mean
With rim brakes, the wheel’s braking surface is part of the system, so rim wear matters alongside pads and cables. On the steel frame, paint damage and moisture entry deserve attention because corrosion can begin at scratches, vent holes or internal surfaces. The $140.00 original MSRP records the bike’s launch positioning, not its present condition or current market value.
Brake service
Rim braking
Pad compound, cable condition and wheel braking-surface wear belong in the inspection.
Frame material
Steel
Paint damage and moisture entry matter because corrosion can start externally or inside the frame.

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 the full range under light load, measure chain wear and inspect the cassette or freewheel teeth. Skipping or hesitation can indicate wear, poor adjustment or mismatched parts.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 →

Historical reference geometry
Geometry
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.
| Measurement | Legacy reference |
|---|---|
| Top tube | 495.3 mm |
| Head-tube angle | 74° |
| Seat-tube angle | 70° |
| Chainstay / rear center | 368.3 mm |
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.
Geometry interpretation
What this geometry means
Legacy reference geometry
Fit reference
The historical source lists a 495.3 mm top-tube length, but it does not identify which frame size this model-level reference describes or whether the historical field was measured horizontally. Treat it as an archival frame reference rather than a size-specific fit recommendation. Its 70° seat-tube angle describes the reference frame’s seat-line orientation. Actual seated position still depends on frame size, saddle height and fore-aft adjustment.
Handling tendencies
The 74° head angle points to relatively quick-steering steering geometry. Wheel size, fork offset, trail and the unknown reference frame size still matter to the final steering feel. The 368.3 mm chainstay records the rear-center dimension of the historical reference. Rear-center length influences weight distribution and how readily the rear of the bike changes direction.
This is historical model-level reference geometry, not a known frame-size geometry table or a ride test. Frame size, rider proportions, cockpit setup, tires, suspension and components can materially change fit and handling.
Specifications are presented as a reference. Components may vary by market, size, production run, or later manufacturer revisions.
