• 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: 500 Series OCLV Carbon, TQ drive system, tapered head tube, IsoSpeed, internal routing, flat mount disc, fender mounts, UDH, 142x12mm chamfered thru axle · Fork: RockShox Rudy XPLR, Solo Air spring, tapered steerer, 45mm offset, 12x100mm thru axle, 40mm travel

• 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 stanchions for scratches or coating wear, look for oil or dirt rings at the seals, and cycle the fork through its travel while checking for binding or bushing play.
• Ask for dated fork-service records. A clean exterior does not establish the condition of internal seals, oil or bushings.

Archived: Shifters: SRAM Force AXS E1 · Rear derailleur: SRAM X0 Eagle AXS, T-Type · Crankset: S: Praxis Alloy, 165mm length / M, ML: Praxis Alloy, 170mm length / L, XL: Praxis Alloy, 172.5mm length · Cassette: SRAM Eagle XS-1295, T-Type, 10-52, 12 speed · Chain: SRAM X0 Eagle, T-Type, 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.

• Identify the installed brake type and actuation before choosing replacement parts or service procedures. Inspect every installed pad and braking surface, then check the complete cable, hose or linkage path for damage, corrosion, leaks or binding.
• 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 · Front tire: Bontrager Girona Pro, Tubeless Ready, GR puncture protection, aramid bead, 60 tpi, 700x42mm · Rear tire: Bontrager Girona Pro, Tubeless Ready, GR puncture protection, aramid bead, 60 tpi, 700x42mm

• 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: 1-1/8'' threadless, sealed cartridge bearings · Handlebar: S: Bontrager Pro Gravel, 40cm width / M, ML: Bontrager Pro Gravel, 42cm width / L: Bontrager Pro Gravel, 44cm width / XL: Bontrager Pro Gravel, 46cm width · Seatpost: Bontrager carbon, 27.2mm, 8mm offset, 330mm length · Saddle: Verse Short Elite, hollow magnesium 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.
