• 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: 800 Series OCLV Carbon, TQ drive system, tapered head tube, rear IsoSpeed, internal routing, flat mount disc, fender mounts, 142x12mm thru axle · Fork: Domane+ carbon, tapered carbon steerer, internal brake routing, fender mounts, flat mount disc, 12x100mm thru axle · 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 Dura-Ace R9270 Di2, 12 speed · Front derailleur: Shimano Dura-Ace R9250 Di2, braze-on, down swing · Rear derailleur: Shimano Dura-Ace R9250 Di2, 34T max cog · Crankset: 50, 52: Praxis Carbon, 165mm length / 54, 56: Praxis Carbon, 170mm length / 58, 60, 62: Praxis Carbon, 172.5mm length · Cassette: Shimano Dura-Ace R9200, 11-34, 12 speed · Chain: Shimano Dura-Ace/XTR M9100, 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.

Archived: Brakes: Shimano Dura-Ace hydraulic disc, flat mount

• 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 · Wheels: (F) Bontrager Aeolus RSL 37, OCLV Carbon, Tubeless Ready, 37mm rim depth, 100x12mm thru axle / (R) Bontrager Aeolus RSL 37, OCLV Carbon, Tubeless Ready, 37mm rim depth, 142x12mm thru axle · Front tire: Bontrager Kwaremont RSL TLR, tubeless ready, folding bead, Race Dual-Compound, 320 tpi, 700x32mm · Rear tire: Bontrager Kwaremont RSL TLR, tubeless ready, folding bead, Race Dual-Compound, 320 tpi, 700x32mm

• 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: 50, 52: Bontrager Pro IsoCore VR-SF, 40cm / 54, 56: Bontrager Pro IsoCore VR-SF, 42cm / 58, 60, 62: Bontrager Pro IsoCore VR-SF, 44cm · Seatpost: 50, 52, 54, 56: KVF aero carbon seatpost, 20mm offset, 280mm length / 58, 60, 62: KVF aero carbon seatpost, 20mm offset, 320mm length · Saddle: Verse Short Pro, carbon rails, 145mm width

• 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.

• Inspect the battery case, mount, lock and electrical contacts for cracks, impact, corrosion, swelling, overheating marks or looseness. Confirm the battery charges normally.
• Confirm the correct charger, battery keys and removable system parts are included. Check charger cables and connectors for damage or improvised repairs.
• Power the system on from cold, check the display for warnings, and test every assist mode. Assistance should engage and stop predictably without intermittent cutouts or abnormal motor noise.
• Ask for available battery-health, cycle-count, diagnostic and firmware records. Confirm that replacement batteries and system support remain available before agreeing on value.

• 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.
