• 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.

Archived: Fork: FOX FLOAT 34 Factory, GRIP2 damper, Kashima Coating, 15x110mm, 44mm offset, 140mm of travel · Rear shock: FOX FLOAT DPS Factory, Rx Trail Tune, EVOL Air sleeve, Kashima Coat, 3-position adjustment w/ Open Mode Adjustment, 190x45mm

• 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: Shifters: SRAM XX1 Eagle AXS · Rear derailleur: SRAM XX1 Eagle AXS · Crankset: SRAM XX1 Eagle, DUB, S1:165mm, S2-S5: 170mm, S6: 175mm; chainrings: 30T · Bottom bracket: SRAM DUB, BSA 73mm, Threaded · Cassette: SRAM XG-1299 Eagle, 10-52t · Chain: SRAM XX1, 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: (F) SRAM G2 ULTIMATE, 4-piston caliper, hydraulic disc, 200mm / (R) SRAM G2 ULTIMATE, 4-piston caliper, hydraulic disc, 180mm

• 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: Rims: Roval Control 240, hookless carbon, 29mm inner width, hand-built, 2Bliss Ready · Hubs: (F) DT Swiss 240, sealed cartridge bearings, 15x110mm spacing, 28h / (R) DT Swiss 240, Ratchet EXP, 36t engagement, SRAM XD driver body, 12mm thru-axle, 148mm spacing, 28h · Front tire: Butcher, GRID casing, GRIPTON® compound, 29x2.3" · Rear tire: Purgatory, GRID Casing, GRIPTON® compound, 29x2.3"

• 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.

Archived: Handlebar: Roval Traverse SL Carbon, riser bar, 6-degree upsweep, 8-degree backsweep, 30mm rise, 780mm, 35.0mm · Stem: Deity, 35.0mm · Seatpost: RockShox Reverb AXS, 30.9, 1X remote, (S1:100mm, S2: 125mm, S3: 150mm, S4-S6: 170mm) · Saddle: Bridge, 155/143mm, Hollow Ti-rails

• 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.
• Cycle the dropper post repeatedly. It should reach full travel, remain extended under load and have no unusual oil, excessive rotational play or damaged remote, cable, hose or battery.

• 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.
