• 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: Tarmac SL6, FACT 9r carbon, Rider-First Engineered™, threaded BB, clean routing, 12x142mm thru-axle, flat-mount disc · Fork: FACT carbon, 12x100mm thru-axle, flat-mount disc · Carbon Fiber

• Inspect the frame in bright light, especially the head tube, bottom-bracket area, chainstays and clamped surfaces. Look for cracks, ripples, crushed sections or signs of impact.
• 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 Tiagra Disc 4720, 10-speed · Front derailleur: Shimano Tiagra, braze-on · Rear derailleur: Shimano Tiagra, 10-speed · Crankset: Shimano Tiagra 4700, 10-speed · Cassette: Shimano, 10-speed, 11-32t · Chain: KMC X10, 10-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.

• Identify the installed brake type and actuation before choosing replacement parts or service procedures. Inspect every installed pad and braking surface, then check the complete cable, hose or linkage path for damage, corrosion, leaks or binding.
• 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.

• 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 Shallow Drop, 6061, 70x125mm, 31.8mm clamp · Stem: Specialized, 3D-forged alloy, 4-bolt, 7-degree rise · Seatpost: Carbon, single-bolt, 27.2mm · Saddle: Body Geometry Power Sport, hollow Cr-Mo rails

• 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.
