• 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: TIG-welded · Fork: Specialized FACT carbon · Carbon/aluminum, aero crown

• 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: Hybrid Mix · Shifters: Shimano R-440-9, Rapidfire · Front derailleur: Shimano Deore, bottom-pull/clamp-on 31.8mm · Rear derailleur: Shimano Ultegra, 9-speed, long cage · Crankset: FSA Gossamer MegaExo, 2-piece, five arm, black polished arms, 52Ax42x30T teeth · Bottom bracket: FSA Mega EXO · Rear cogs: 9-speed, 12 - 26 teeth · Chain: Shimano CN-HG73

• 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: Avid Juicy 5, hydraulic disc brake with 6" Clean-Sweep rotor brakes, Avid Juicy 5 levers

• 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: 700c wheels · Rims: Alex AT-400, 28-hole/32-hole · Hubs: Front: Specialized Forged Alloy, disc brake compatible, double sealed, QR, Rear: Specialized Forged Alloy, disc brake compatible · Front tire: 700 x 28c Specialized All Condition, aramid bead, 120TPI w/Armadillo

• 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" Intellaset threadless, alloy cap, alloy cone spacer · Handlebar: Specialized, carbon, 580mm width, 3 ply weave · Stem: Specialized 3D forged alloy, 6 degree rise · Seatpost: Specialized Pavé, advanced carbon, 27.2mm diameter · Saddle: Body Geometry Avatar, microfiber, hollow Cr-Mo rails · Pedals: Shimano 520R, SPD

• 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.
