• 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 SL4 FACT 8r carbon, 1-1/8" to 1-3/8" headtube, compact race design, Zertz, internal rear brake cable, OSBB · Fork: Specialized FACT carbon, disc · Carbon Fiber

• Inspect the frame in bright light, especially the head tube, bottom-bracket area, chainstays and clamped surfaces. Look for cracks, ripples, crushed sections or signs of impact.
• 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: Shimano 685 · Front derailleur: Shimano Ultegra, 11-speed, braze-on · Rear derailleur: Shimano Ultegra, 11-speed, long cage · Crankset: Praxis Works, TURN Zayante, BB30, 50/34 · Bottom bracket: BB30 · Rear cogs: Shimano 105, 11-speed · Chain: Shimano 105, 11-speed

• 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: Shimano 785, hydraulic disc, Ice Tech resin pads w/ fins, 140mm RT-99 Ice Tech rotor

• 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 · Rims: AXIS 4.0 Disc, SCS · Hubs: AXIS 4.0 Disc, SCS · Front tire: Specialized Turbo Pro, 127TPI, folding bead, BlackBelt protection, 700x25c

• 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, 1-3/8" lower, Cr-Mo cartridge bearings, 20mm cone spacer, w/ 20mm of spacers · Handlebar: Specialized Comp, shallow drop, 6061 alloy, 125mm drop, 70mm reach · Stem: Specialized Comp Multi, 3D forged alloy, 4-bolt, 12-degree rise · Seatpost: Specialized CG-R, FACT carbon, single bolt, 27.2mm · Saddle: Body Geometry Toupé Comp Gel, hollow Cr-Mo rails, 143mm · Pedals: Nylon flat test ride, loose-ball, 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.
