• 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 SL8 FACT 10r Carbon, Rider First Engineered™, Win Tunnel Engineered, Clean Routing, Threaded BB, 12x142mm thru-axle, flat-mount disc · Fork: FACT 10r 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 Ultegra Di2 R8170, hydraulic disc · Front derailleur: Shimano Ultegra Di2 R8150, braze-on · Rear derailleur: Shimano Ultegra Di2 R8150, 12-speed · Crankset: Shimano Ultegra R8100 · Bottom bracket: Shimano Threaded BSA BB · Cassette: Shimano Ultegra, 12-speed, 11-30t · Chain: Shimano Ultegra, 12-speed

• Confirm every shift battery charges and every control operates. Shift through the full cassette under light load while checking pairing, derailleur alignment and response at both ends of the range.
• 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.

• 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: Wheels: (F) Roval C38, 21mm internal width carbon rim / (R) Roval C38, 21mm internal width carbon rim, tubeless ready · Front tire: S-Works Turbo, folding bead, 700x26mm · Rear tire: S-Works Turbo, folding bead, 700x26mm

• Spin both wheels and watch for side-to-side and vertical movement. Check spoke tension, rim condition and hub play. Inspect the carbon rims closely for impact marks, cracks, delamination or damage around spoke holes and bead hooks.
• 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.
• Confirm whether the bike is actually set up tubeless, whether both tires hold pressure, and when sealant and rim tape were last serviced.

Archived: Handlebar: Specialized Expert Shallow Drop, alloy, 125mm drop x 75mm reach · Stem: Tarmac integrated stem, 6-degree · Seatpost: S-Works Tarmac SL8 Carbon seat post, FACT Carbon, 15mm offset · Saddle: Body Geometry Power Expert

• 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.
