• 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 A1 SL Aluminum, EVO 650b geometry, fully butted tubesets, ORE downtube, tapered headtube, forged dropouts w/ disc mount, replaceable alloy derailleur hanger · Fork: Custom SR Suntour XCR-AIR 650b, w/ custom Multi-Circuit Damping, mag lowers, air spring, Hi-Ten 32mm stanchions, tapered alloy steerer, hydraulic lockout w/ preload adjust, disc mount, size-specific 100/120mm travel · 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.

Archived: Fork: Custom SR Suntour XCR-AIR 650b, w/ custom Multi-Circuit Damping, mag lowers, air spring, Hi-Ten 32mm stanchions, tapered alloy steerer, hydraulic lockout w/ preload adjust, disc mount, size-specific 100/120mm travel

• 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: Group: Mountian mix · Shifters: SRAM X5, 2x10, trigger · Front derailleur: SRAM X5, 2x10, high mount · Rear derailleur: SRAM X7 Type 2, 10-speed, medium cage · Crankset: Specialized Stout XC, 2x10, 2 pc., 24mm spindle, 36/22, anti-corrosion hardware · Bottom bracket: 24mm BSA for 2 pc. design, 73mm · Rear cogs: Sunrace, 10-speed, 11-36 · Chain: KMC X10, 10-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.

Archived: Brakes: Tektro Gemini, hydraulic disc, resin pads, I-spec compatible

• 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: 27.5 · Rims: Stout XC, 650b disc, alloy double-wall, pin joint, 26mm inner width, 32h · Hubs: Specialized Hi Lo disc, alloy, RCC bearing system, QR, 32h, Specialized Stout XC disc, alloy, RCC bearing system, QR, 32h · Front tire: Specialized Ground Control Sport, 60TPI, wire bead, 650bx2.3", Specialized Ground Control Sport, 60TPI, wire bead, 650bx2.3"

• 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: Headset: 1-1/8" upper, 1-1/2" lower, Campy style, integrated sealed cartridge bearings · Handlebar: Specialized, low rise bar, double butted 6061 alloy, 9-degree backsweep, 5-degree upsweep, 15mm rise, 31.8mm · Stem: Specialized 3D forged alloy, 4-bolt, 6-degree rise, anti-corrosion hardware · Seatpost: Alloy, 2-bolt, micro-adjust, 12.5mm offset, 30.9mm, anti-corrosion hardware · Saddle: Body Geometry mountain, steel rails, 143mm · 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.
• 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.
