• 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: A1 alloy, Sport XC 29 Geometry, zero-stack head tube, internal cable routing, 135x9mm forged dropouts, chainstay-mounted disc brake, replaceable alloy derailleur hanger · Fork: SR Suntour XCT 29, coil spring, custom Multi-Circuit damping, quick-release, 46mm offset, 80/90/100mm of travel (size-specific)

• 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.

Archived: Shifters: Shimano EF505, EZ-Fire Plus, 8-speed · Front derailleur: Shimano Altus, 3-speed · Rear derailleur: Shimano Acera, 8-speed · Crankset: Stout, forged alloy, 3x8; chainrings: Steel, 44/34/24T · Bottom bracket: Square taper, 73mm, internal bearings · Cassette: SunRace, 8-speed, 11-34t · Chain: KMC X8EPT, 8-speed, anti-corrosion coating w/ reusable Missing Link™

• 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) Shimano BR-MT200, hydraulic disc, 160/180mm / (R) Shimano BR-MT200, hydraulic disc, 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: Specialized Alloy 29, 25mm internal width, disc-specific · Hubs: (F) Shimano, Center Lock™ disc, 9x100mm spacing, quick-release, 28h / (R) Shimano, Center Lock™ disc, 9x135mm spacing, quick-release, 32h · Front tire: Ground Control Sport, 29x2.3" · Rear tire: Fast Trak Sport, 29x2.1"

• 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.

Archived: Handlebar: Stout XC, double-butted alloy, 8-degree backsweep, 6-degree upsweep, 10mm rise, 31.8mm · Stem: Stout 3D-forged alloy, 31.8mm, 6-degree rise · Seatpost: Alloy, 12mm offset, 2-bolt clamp, 30.9mm · Saddle: Henge Sport, steel rails, 143mm · Pedals: Specialized Dirt

• 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.
