• 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: Carbon fiber · Fork: RockShox Lyrik Ultimate, DebonAir+ w/ ButterCups, Charger 3.1 RC damper, tapered steerer, 44mm offset, Boost110, 15mm Maxle Stealth, 150mm 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.

Archived: Fork: RockShox Lyrik Ultimate, DebonAir+ w/ ButterCups, Charger 3.1 RC damper, tapered steerer, 44mm offset, Boost110, 15mm Maxle Stealth, 150mm travel · Rear shock: RockShox Deluxe Ultimate RC2T, 205mm x 60mm

• 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.
• Inspect the shock shaft and seals, cycle the rear suspension through its travel and check for oil, air loss, binding or unusual top-out and bottom-out noises.
• Hold the rear brake and load the suspension from several directions. Check pivots, bearings and mounting hardware for knock, looseness or side play.
• Ask for dated fork, shock and pivot-service records. A clean exterior does not establish the condition of internal seals, oil, bushings or bearings.

Archived: Group: SRAM X0 Eagle AXS T-Type, 12-speed · Shifters: SRAM AXS pod · Rear derailleur: SRAM X0 Eagle AXS, T-Type · Crankset: SRAM X0 Eagle, DUB, 30T, T-Type, 55mm chainline, 170mm length · Bottom bracket: SRAM DUB MTB Wide, 73mm, BSA threaded · 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.

Archived: Brakes: SRAM Maven Silver 4-piston hydraulic disc

• 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: Headset: 1-1/8'' threadless, sealed cartridge bearings · Handlebar: Race Face ERA, carbon, 35mm, 40mm rise, 800mm width · Stem: Race Face Turbine R, 35mm, 0 degree, 40mm 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. 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.
