• 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 M5 Aluminum, fully butted w/ Smooth Welds, tapered head tube and seat tube, forged post-mount 160mm disc dropouts, internal routing, forged bottom bracket shell, 197x12mm rear thru-axle · Fork: Specialized FACT carbon, 46mm offset, tapered steerer, 150mm axle · 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: Shifters: SRAM SX Eagle, trigger, 12-speed · Rear derailleur: SRAM SX Eagle, 12-speed · Crankset: SRAM X01 Eagle, DUB, 30T · Chain: SRAM SX Eagle, 12-speed w/ PowerLock®

• 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.

Archived: Brakes: (F) SRAM Level T, hydraulic disc, 200/180mm / (R) SRAM Level T, hydraulic disc, 180/160mm

• 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: Stout XC 80, 27.5", alloy, 76mm internal width, disc-specific, tubeless ready · Hubs: (F) Stout Pro 150, sealed cartridge bearings, 6-bolt disc, 15x150mm, 32h / (R) Stout Pro 197, sealed cartridge bearings, 6-bolt disc, 12x197mm, 32h · Front tire: Maxxis Minion FBF, 120 TPI, EXO, 27.5 x 3.8" · Rear tire: Maxxis Minion FBR, 120 TPI, EXO, 27.5 x 3.8"

• 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.
• Confirm whether the bike is actually set up tubeless, whether both tires hold pressure, and when sealant and rim tape were last serviced.

Archived: Handlebar: Stout Riser, double-butted alloy, 9-degree backsweep, 5-degree upsweep, 15mm rise, 750mm / 780mm width, 31.8mm · Stem: Specialized, 3D-forged alloy, 4-bolt, 7-degree rise · Seatpost: Specialized 2-bolt head, forged alloy, 8mm offset, micro-adjust, 30.9mm · Saddle: Specialized Bridge, size specific, 143/155

• 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.
