• 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.

Archived: Frame: Specialized A1 Premium Aluminum, Ground Control Positioning, formed tubes, disc mount, fender/rack mounts, reflective paint · Fork: A1 Premium Aluminum, Cr-Mo steerer, post disc mount, fender/rack mounts, reflective paint · Aluminum

• 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 Deore, 10-speed · Rear derailleur: Shimano Deore, Shadow Plus design, SGS cage, 10-speed · Crankset: Single crank, 130mm BCD spider; chainrings: 42T w/aluminum chainguard · Bottom bracket: BSA, square taper, cartridge bearings · Cassette: SunRace, 10-speed, 11-40t · Chain: KMC X10, 10-speed w/reusable MissingLink

• 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) Shimano Acera, hydraulic disc, resin pads, 160mm rotor / (R) Shimano Acera, hydraulic disc, resin pads, 160mm rotor

• Squeeze each lever firmly. It should feel consistent and return cleanly. Check levers, hoses and calipers for fluid, inspect pad thickness and contamination, and examine rotors for wear or bending.
• 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: Specialized Roll, double-wall, 33mm inner width, disc · Hubs: (F) Specialized disc, double-sealed, loose ball bearings, 9mm QR / (R) Specialized disc, loose ball bearings, for Shimano 10-speed cassette, QR · Front tire: Nimbus Sport Reflective, 60 TPI, 27.5 x 2.3" · Rear tire: Nimbus Sport Reflective, 60 TPI, 27.5 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, alloy, 10-degree backsweep 31.8mm · Stem: Specialized Flowset, 3D-forged alloy, 12-degree rise, 31.8mm clamp · Seatpost: Alloy, 12mm offset, 2-bolt, 27.2mm · Saddle: Milano Sport, steel rails · 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.
