• 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.

• 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: Group: Shimano Ultegra · Shifters: Shimano Dura-Ace, bar-end control, 11 speed · Front derailleur: Shimano Ultegra, braze-on · Rear derailleur: Shimano Ultegra · Crankset: Shimano Ultegra, 52/36 (semi-compact) · Rear cogs: Shimano Ultegra 11-25, 11 speed · Chain: Shimano Ultegra

• 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: Bontrager Speed Limit integrated, Bontrager Race Lite aero levers

• 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: 700c · Rims: Bontrager Race Tubeless Ready · Hubs: Bontrager Race Tubeless Ready · Front tire: Bontrager R3 Hard-Case Lite, 700x23c

• 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.
• Confirm whether the bike is actually set up tubeless, whether both tires hold pressure, and when sealant and rim tape were last serviced.

Archived: Headset: Integrated, sealed bearings · Handlebar: Bontrager Speed Concept full foil aero bar, carbon, direct mount · Stem: Bontrager Speed Concept, direct mount · Seatpost: Bontrager Speed Concept Race Lite, Alloy, +/-20mm offset · Saddle: Bontrager RXL Hilo, hollow titanium 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. Look particularly closely for crushing, scoring or cracks at carbon handlebar clamp areas.
• 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.
