• 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: Specialized M4 Premium Aluminum, fully butted w/ smooth welds, tapered headtube, post-mount disc dropouts, 190mm rear hub spacing, replaceable alloy derailleur hanger · Fork: RockShox Bluto RL, Solo Air spring, TurnKey damping, tapered alloy steerer, external rebound adj., 32mm alloy stanchions w/ mag lowers, disc mount, QR 15mm thru-axle for 150mm hub spacing · Suspension

• Look for dents or shape changes and inspect the edges of welds around the head tube, bottom bracket, seat cluster and suspension mounts for hairline cracks.
• 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.

• Shift through every available gear under light load. Hesitation, skipping or inconsistent indexing can reflect wear, damage, poor adjustment or mismatched replacement parts.
• 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.

• 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: 26 · Rims: Specialized Fatboy SL, alloy disc, single wall, 90mm wide, sleeve joint, hookless design, 32h · Hubs: Specialized Hi Lo disc, sealed cartridge bearings, 15mm thru-axle, 150mm wide, 32h, Specialized Hi Lo disc, alloy, sealed cartridge bearings, XD driver body, 190mm wide, QR, 32h · Front tire: Specialized Ground Control Fat, 120TPI, folding bead, 26x4.6", Specialized Ground Control Fat, 120TPI, folding bead, 26x4.6"

• 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.

• 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.
• 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.
