• 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: Specialized FACT carbon, full monocoque, tapered steerer, 135mm hub spacing, open QR dropouts · Carbon Fiber

• 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 crown, blades, dropouts and visible steerer area. Check that it is straight, securely installed and free of cracks or impact damage.

Archived: Group: SRAM XX1 · Shifters: SRAM XX1, 11-speed, trigger · Rear derailleur: SRAM XX1, 11-speed, carbon cage · Crankset: Race Face Next SL, PF30 BB, 100mm spindle, 30T, spiderless · Rear cogs: SRAM XX1, 11-speed, 10-42 · Chain: KMC X11L, 11-speed, w/ reusable MissingLink

• 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: HED Big Deal, carbon, single wall, tubeless, 85mm wide, 32h · Hubs: Specialized Stout XC 135, Hi Lo disc, alloy, sealed cartridge bearings, QR, 32h, Specialized Stout XC 190, Hi Lo disc, alloy, sealed cartridge bearings, 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 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.
• 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" upper, 1-1/2" lower, Campy style, integrated sealed cartridge bearings · Handlebar: Specialized flat, carbon, 8-degree backsweep, 31.8mm · Stem: Specialized Stout XC, 3D forged alloy, 4-bolt, 6-degree rise, anti-corriosion hardware · Pedals: Alloy, 1 pc. body, 9/16", w/ reflectors

• 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.
