• 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: Shimano Dura-Ace Di2 hydro disc, 2x11 · Front derailleur: Shimano Dura-Ace Di2, braze-on · Rear derailleur: Shimano Dura-Ace Di2 · Crankset: HollowGram SiSL2 w/ pre-installed power2max NG Eco Power Meter (not activated), BB30a, Vision rings, 52/36 · Bottom bracket: Cannondale Alloy PressFit30 · Rear cogs: Shimano Dura-Ace, 11-30, 11-speed · Chain: Shimano Dura-Ace, 11-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.

Archived: Brakes: Shimano Dura Ace Di2 hydro disc, 160/140mm RT900 rotors

• Inspect pads, rotors, calipers and the complete cable or hose path. Both levers should feel consistent and both calipers should release without persistent rubbing.
• 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: HollowGram 64 SL KNØT, Carbon, 20h front, 24h rear, 64mm deep, 21mm ID, tubeless ready · Hubs: (F) HollowGram KNØT, sealed bearing 12x100 centerlock / (R) HollowGram KNØT, 12x142 centerlock w/ DT Swiss internals · Front tire: Vittoria Rubino Pro Speed, 700 x 26mm (23c) · Rear tire: Vittoria Rubino Pro Speed, 700 x 26mm (23c)

• 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: Headset: Tapered, 1-1/8” upper, 1-1/4” lower bearing · Handlebar: HollowGram SystemBar KNØT, alloy w/ cable cover · Stem: HollowGram Stem KNØT, alloy w/ cable cover, -17° · Seatpost: HollowGram 60 KNØT Carbon, 330mm · Saddle: Prologo Dimension Nack NDR, 143mm width, carbon rails · Pedals: Not Included

• 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.
