Velopedia analysis

What the specifications mean

Derived from the archived manufacturer record

The calculated 436% cassette spread is a clearer measure of gearing breadth than the component-group name by itself. The mixed wheel system uses different front and rear bead-seat diameters, so tires, tubes, rims and spare wheels are not interchangeable end to end. For the steel frame, paint damage and moisture entry matter because corrosion can begin at scratches, vent holes or internal surfaces.

Gearing 436% cassette range Calculated from the published 11–48-tooth sprocket span.

Wheel system Mixed 29 / 27.5 Front and rear tires, tubes, rims and spare wheels use different diameters.

Frame inspection Steel Paint damage and moisture entry matter because corrosion can start externally or inside the frame.

Bottom bracket Threaded interface Shell width, thread standard and crank-spindle interface still require confirmation.

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.

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.
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.
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.
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.
Bottom bracketTurn the cranks slowly, feel for rough bearings and check for side-to-side play. Creaking under load deserves investigation but does not identify the source by itself.

This interpretation explains relationships in the published data. Confirm exact standards and dimensions before ordering parts or performing service.
