• 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.

• 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 Altus, 7-speed · Rear derailleur: Shimano Tourney, 7-speed · Crankset: Cold-forged alloy crankarms, 3-piece construction, 104mm BCD spider, 4-arm w/steel chainring; chainrings: 42T w/steel chainguard · Bottom bracket: BSA, square taper, cartridge bearings · Cassette: Shimano Tourney freewheel, 7-speed, 14-34t · Chain: KMC Z51, 7-speed

• 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.

Archived: Brakes: (F) Tektro V-brake, linear pull / (R) Tektro V-brake, linear pull

• Inspect pads, cables and housings, then examine both rim braking surfaces for concavity, cracking or heavy wear. Confirm each caliper returns and centers correctly.
• 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 rim brake, double-wall aluminum, 16mm rim depth, 30.4mm internal width, 32h · Hubs: (F) Specialized V-brake, alloy, loose ball bearings, 9mm, QR / (R) Specialized V-brake, loose ball bearings, QR, 32h · Front tire: Nimbus Sport, 60 TPI, BlackBelt protection, 650b x 2.3"" · Rear tire: Nimbus Sport, 60TPI, 650bx2.3"", BlackBelt protection

• 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, 5-degree upsweep, 125mm rise, 31.8mm · Stem: Forged alloy, 17-degree rise, 31.8mm clamp · Seatpost: Alloy, 12mm offset, 2-bolt clamp, 27.2mm · Saddle: Body Geometry The Cup, 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.
