• 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.

Archived: Frame: Double-butted Reynolds 520 Cr-Mo, 21" toptube, externally relieved MID BB shell, integrated headset, hydroformed chainstays, removable seatstay-mounted U-brake boss, 5mm thick dropouts for 14mm axle · Fork: Cr-Mo, butted/tapered blade, 1-1/8" threadless, 1pc.

• Check paint damage, vent holes and accessible internal surfaces for corrosion. Look for dents, bent tubes and cracking around welded or brazed joints.
• 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: Group: BMX mix · Crankset: P.Crank, 3 pc. Cr-Mo, tubular arms, 48-spline, 25T, Cr-Mo, P.Spline sprocket · Bottom bracket: MID BB, 2x sealed cartridge bearings w/ 19mm, 48-spline Cr-Mo spindle · Chain: KMC Z510H, BMX 1/2" x 1/8", anti-drop inner links

• 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: Tektro, U-brake, coil spring, 1 pc. pads, 15mm offset arms

• Inspect pads and braking surfaces, check the complete cable or hose path, and confirm both controls feel consistent and return cleanly.
• 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: Wheel size: 20 · Rims: P.20, alloy double-wall, triple void, 35mm inner width, 36h · Hubs: P.Series BMX, bolt-in, sealed cartridge bearings, 36h, P.Series BMX, alloy, sealed cartridge bearings, hollow axle, 36h · Front tire: Specialized Compound Street, 30TPI, wire bead, 20x2.3"

• 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: Headset: 1-1/8" integrated threadless, Campy style, full cartridge bearings, 8mm cone spacer · Handlebar: Specialized P.Series BMX, steel, 11-degree backsweep, 2-degree upsweep, 217mm rise, 22.2mm · Stem: P.Series BMX, forged alloy, top load, 52mm, 22.2mm clamp · Seatpost: Alloy, 0mm offset, 25.4mm, integrated w/ saddle · Saddle: P.Seat SL, 1 pc. w/ co-molded alloy 25.4mm seatpost · Pedals: Specialized P.Series, nylon platform w/ molded pins, loose ball, 9/16"

• 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.
