• 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: Shifters: SRAM Apex AXS, 12-speed · Rear derailleur: SRAM GX Eagle AXS, T-Type, 12-speed · Crankset: SRAM Apex 1 Wide, 40T: 165mm (47cm), 170mm (51cm), 172.5 (54-56cm), 175mm (58-61cm) · Bottom bracket: SRAM DUB BSA Road 68 Wide · Rear cogs: SRAM XS-1270, 10-52, T-Type, 12-speed · Chain: SRAM Apex, 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: Wheel size: 700c · Rims: WTB KOM Team i25 TCS, 28h, tubeless ready · Hubs: (F) Shimano TC500, 12x100mm centerlock / (R) Shimano TC500, 12x142mm centerlock · Front tire: WTB Vulpine TCS Light, 700x45c, tubeless ready · Rear tire: WTB Vulpine TCS Light, 700x45c, tubeless ready

• 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: Acros IS52/40 ICR · Handlebar: Cannondale 2 ShortDrop, 7050 alloy, 12 deg flare, 105mm drop: 400mm (47cm), 420mm (51-54), 440mm (56-61cm) · Stem: Cannondale C1 Conceal, Alloy, 31.8, -6°: 70mm (47-51m), 80mm (54cm), 90mm (56-58cm), 100mm (61cm) · Seatpost: Cannondale 2 Carbon, 27.2x350mm (47-58), 400mm (61) · Saddle: Fizik Terra Argo X7, S-Alloy rails, 150mm

• 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.
