• Confirm the frame markings and seller description match this archived model. Note every component that differs from the published build.
• Record the frame serial number. It should be legible, unaltered and consistent with the seller’s ownership history.
• Find the size marking on the bicycle and confirm the fit before judging the condition or price.

• Look for dents or shape changes and inspect the edges of welds around the head tube, bottom bracket, seat cluster and suspension mounts for hairline cracks.
• Stand behind and in front of the bicycle to look for obvious frame, fork or wheel misalignment. Ask directly about crashes, transport damage and repairs.
• Inspect the fork crown, blades, dropouts and visible steerer area. Check that it is straight, securely installed and free of cracks or impact damage.

Archived: Shifters: Shimano EF500, 7-speed · Front derailleur: Shimano Tourney FD-TY710 · Rear derailleur: Shimano Altus, 7-/8-speed · Crankset: Shimano Tourney, 3-piece, 46/30T · Bottom bracket: BSA, square-taper, 68mm · Cassette: Shimano HG200, 7-speed, 12-32t · Chain: KMC Z7, 7-speed w/ Missing Link™

• Shift through every available gear under light load. Hesitation, skipping or inconsistent indexing can reflect wear, damage, poor adjustment or mismatched replacement parts.
• Measure chain wear with a compatible gauge and inspect chainring, cassette or freewheel teeth. A new chain does not rule out wear in the remaining drivetrain.
• Turn the cranks slowly, feel for rough bearings and check for side-to-side play. Inspect crank arms, chainring bolts and pedal threads for looseness or damage.

• Check both cables and housings for corrosion, fraying or drag. Confirm each caliper releases cleanly, then inspect pad thickness, rotor wear and rotor alignment.
• Before riding, test every installed brake separately at walking speed. Each should stop firmly and release cleanly without its control reaching the end of its usable travel.

Archived: Rims: 650b disc, double-wall alloy, pinned, 32h · Hubs: (F) Alloy, 6-bolt disc, loose ball bearing, quick-release, 32h / (R) Alloy, 6-bolt disc, 7-speed freehub, loose ball bearing, quick-release, 32h · Front tire: Nimbus II Sport, 650b x 2.3" · Rear tire: Nimbus II Sport, 650b x 2.3"

• Spin both wheels and watch for side-to-side and vertical movement. Check spoke tension, rim condition and hub play.
• Inspect both tire casings for cuts, cracking, plugs, bulges or exposed threads and confirm the installed sizes are safe for the rims and available frame and fork clearance.
• Remove and reinstall or closely inspect both wheel-retention systems. Axles or quick releases should tighten correctly with undamaged threads, hardware and dropouts.

Archived: Handlebar: Specialized Roll, 6061 alloy, 15-degree backsweep, 125mm rise, 31.8mm · Stem: Specialized, 3D-forged alloy, 4-bolt, 7-degree rise · Seatpost: Spring suspension, alloy, 27.2mm, 2-bolt clamp · Saddle: Body Geometry "The Cup," 6-degree rise, steel rails, 245mm · Pedals: Specialized City, platform

• Apply the front brake and rock the bike to check for headset play or notchiness. Inspect the stem, handlebar and clamp zones, then confirm every fastener and control is secure.
• Check that the seatpost moves for adjustment and that the saddle, post and clamp hold securely without cracks, severe corrosion or damaged hardware.

• Before riding, confirm both wheels are secure, tires are safe, both brakes function, and the headset, handlebar, stem, cranks and pedals have no looseness.
• Begin at low speed. Test steering, braking and shifting progressively, then load the drivetrain and suspension only after the basic safety checks pass.
• Listen and feel for repeated knocks, grinding, skipping, brake pulsation or movement at joints. Stop the test if the bicycle cannot be controlled safely.
