• 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 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 Pod Controller, MMX Bridge · Rear derailleur: SRAM GX Eagle AXS T-Type, 12sp · Crankset: SRAM Eagle, 30T, CL55, 165mm (S1,S2) -170mm (S3,S4,S5) · Bottom bracket: SRAM DUB, BSA 73mm, MTB WIDE · Cassette: SRAM 1275 Eagle T-Type, 10-52T, 12sp · Chain: SRAM GX Eagle T-Type, 12spd

• 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 Code Silver Stealth, 4-Piston, Sintered Pads / (R) SRAM Code Silver Stealth, 4-Piston, Sintered Pads; Rotors: (F) SRAM Centerline, 180mm, 1.8mm Thickness, 6-bolt / (R) SRAM Centerline, 180mm, 1.8mm Thickness, 6-bolt; Levers: SRAM Code Silver Stealth

• Inspect pads and braking surfaces, check the complete cable or hose path, and confirm both controls feel consistent and return cleanly.
• 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: 29"; 29"/27.5" · Rims: Stan's Flow S2, 32H, F/R- 29", 30mm ID · Hubs: (F) DT Swiss 370, 15x110 Boost, 32H, 6-bolt / (R) DT Swiss 370, 12x148 Boost, XD, 6-bolt · Front tire: Maxxis Minion DHF, 3C Max Terra EXO, 29x2.5", Folding · Rear tire: Maxxis Dissector 2.4", 3C, MaxxTerra / EXO / TR, Folding

• 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. This record indicates different front and rear wheel diameters, so verify each tire at its correct end.
• Remove and reinstall or closely inspect both wheel-retention systems. Axles or quick releases should tighten correctly with undamaged threads, hardware and dropouts.

Archived: Headset: FSA No. 57 ZS, Sealed Bearing, Tapered 1-1/8" - 1.5", ( ZS44/28.6 | ZS56/40 ) · Handlebar: OneUp Aluminum, 800mm, 20mm rise · Stem: OneUp 42mm length , 35mm clamp · Seatpost: TranzX YS105, 34.9mm, 150 (S1) -170mm (S2) -200mm (S3,S4) -230mm (S5) · Saddle: Ergon SM-1 Enduro

• 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.
