Velopedia analysis
What the specifications mean
The fork provides the documented suspension, so fork setup and rear-tire pressure are the main adjustments for balancing the two ends of the bike. 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.
Suspension setup
Front only
Fork settings affect the front while rear-wheel behavior remains dependent on tire and wheel setup.
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
Nominal 26 inch
Confirm the ISO bead-seat diameter because several incompatible standards have used this name.
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 →
- SuspensionAsk when the fork was last serviced. Check the stanchions for damage, look for oil at the seals and make sure the fork moves smoothly without bushing play.Evaluate the suspension →
- 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Historical reference geometry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 | 563.9 mm |
| Head-tube angle | 71° |
| Seat-tube angle | 73° |
| Chainstay / rear center | 424.2 mm |
| Wheelbase | 1059.2 mm |
| Fork offset / rake | 38.1 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 563.9 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 71° head angle points to relatively quick-steering by current mountain-bike conventions steering geometry. Wheelbase is listed at 1059.2 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 38.1 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 71°, the head angle sits close to the middle of the group 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.
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.
