Velopedia analysis
What the specifications mean
The 255% cassette range describes the available gearing more clearly than the component-group name alone. On the steel frame, paint damage and moisture entry deserve attention because corrosion can begin at scratches, vent holes or internal surfaces. 700C · 622 mm identifies the rim diameter, while tire width and available frame or fork clearance remain separate compatibility questions.
Gearing
255% cassette range
Calculated from the published 11–28-tooth sprocket span.
Frame material
Steel
Paint damage and moisture entry matter because corrosion can start externally or inside the frame.
Wheel standard
700C · 622 mm
The label fixes rim diameter, not tire width or available frame and fork clearance.
Published weight
29.5
Frame size, pedals, tire setup and production substitutions can change the measured result.
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 →
- BrakesTest each brake separately and confirm it stops firmly and releases cleanly. Inspect the pads and braking surfaces for wear or contamination, and check the cables or hoses for damage.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 →

Historical reference geometry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 | 558.8 mm |
| Head-tube angle | 72° |
| Seat-tube angle | 73° |
| Chainstay / rear center | 439.4 mm |
| Wheelbase | 1051.6 mm |
| Fork offset / rake | 45.7 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 558.8 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 73° 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 72° head angle points to moderate steering geometry. Wheelbase is listed at 1051.6 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 45.7 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.
Period context
At 72°, the head angle sits toward the steeper end among hybrid geometries represented in Velopedia for this period. Its 73° seat angle is close to the middle of the group among the same-period hybrid references.
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.
