• 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 E5 Premium Aluminum, fully manipulated butted tubing w/ smooth welds, internal cable routing, tapered/integrated headset, fender/rack eyelets · Fork: Specialized FACT carbon w/ Zertz, alloy steerer/crown · Carbon Fiber/Aluminum

• 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: Shimano Tiagra · Shifters: Shimano Tiagra, 10-speed · Front derailleur: Shimano Tiagra · Rear derailleur: Shimano Tiagra, 10-speed, long cage · Crankset: FSA Omega, forged alloy, 50/34 · Rear cogs: Shimano Tiagra, 10-speed, 12-30 · Chain: KMC X10, 10-speed, 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: Tektro Gemini, hydraulic disc, resin pads

• 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 1.0 Disc · Hubs: AXIS 1.0 Disc · Front tire: Specialized Espoir Sport Reflect, 60TPI, wire bead, Double BlackBelt protection, 700x30c

• 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" sealed Cr-Mo bearings integrated w/ headset, 15mm alloy cone spacer · Handlebar: Specialized flat, 6061 double butted alloy, 10-degree backsweep, 4-degree upsweep, 31.8mm · Stem: Specialized Comp Multi, 3D forged alloy, 4-bolt, 12-degree rise · Seatpost: Alloy, 2-bolt, 12.5mm offset, 30.9mm, anti-corrosion hardware · Saddle: Body Geometry Targa Sport, steel rails, 155mm · Pedals: Sirrus, 1.5mm Varus angle, nylon body, symmetric alloy cage, low profile bearing system, toe clip capable

• 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.
