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 alloy frame, dents and hairline cracks around welds matter more than cosmetic scratches. Pay closest attention near the head tube, bottom bracket shell, dropouts and other heavily loaded junctions. The archive lists a published weight of 23.5 lb. Treat it as a reference for the documented build because frame size, pedals, tire setup and production substitutions can change the actual scale reading.
Brake service
Rim braking
Pad compound, cable condition and wheel braking-surface wear belong in the inspection.
Frame material
Aluminum / alloy
Dents and cracking around welds at the head tube, bottom bracket shell and dropouts deserve attention.

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 →
- 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Historical reference geometry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 | 533.4 mm |
| Head-tube angle | 75° |
| Seat-tube angle | 71° |
| Chainstay / rear center | 393.7 mm |
| Wheelbase | 965.2 mm |
| Fork offset / rake | 30.5 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 533.4 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 71° 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 75° head angle points to relatively quick-steering steering geometry. Wheelbase is listed at 965.2 mm, but because the historical source does not identify frame size, it is retained as a model reference rather than used for a size-normalized handling conclusion. Fork offset is listed at 30.5 mm. Offset works with head angle and wheel size to determine trail, so it is useful steering evidence even though the archive does not provide enough information here to calculate trail reliably.
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.
