• 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: Specialized A1 Premium Aluminum, Fitness Geometry, butted tubing, internal cable routing, flat-mount disc, Plug + Play rack/fender mounts · Fork: Specialized FACT 9r Carbon, flat-mount disc, quick-release · Carbon Fiber

• 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: microSHIFT, 9-speed · Front derailleur: Shimano Sora FD-R3000, 31.8mm clamp · Rear derailleur: Shimano Sora, 9-speed · Crankset: Shimano MT210, 46/30, chainguard · Bottom bracket: Shimano 68mm threaded · Cassette: Shimano CS-HG400, 9-speed, 11-34t · Chain: KMC X9, 9-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.

Archived: Brakes: (F) Tektro HD-R280, hydraulic disc, 160 mm rotor / (R) Tektro HD-R280, hydraulic disc, resin pads, flat-mount, 140mm

• 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: 700C disc brake, double-wall alloy, 22mm depth, 21mm internal width · Hubs: (F) Alloy, 6-bolt disc, loose ball bearing, quick-release, 32h / (R) Alloy, 6-bolt disc, 8-/9-speed freehub, loose ball bearing, quick-release, 32h · Front tire: RoadSport Reflect, Wire bead, Blackbelt/Endurant Casing, 700x32c · Rear tire: RoadSport Reflect, Wire bead, Blackbelt/Endurant Casing, 700x32c

• 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: Double-butted alloy, 9-degree backsweep, 31.8mm · Stem: 3D-forged alloy, 31.8mm, 7-degree rise · Seatpost: Alloy, 12mm offset, 2-bolt clamp, 27.2mm · Saddle: Bridge Sport, Steel rails, 155/143mm · Pedals: Specialized Body Geometry Fitness, Platform, Plastic

• 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.
