• 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, Fitness Geometry, fully-manipulated butted tubing w/smooth welds, internal cable routing, tapered/integrated headset, post disc mount, Plug + Play fender mount, reflective paint · Fork: Specialized FACT carbon fiber, alloy steerer/crown, Zertz inserts, post disc mount, Plug + Play fender mount, reflective paint · Carbon Fiber

• 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: Front derailleur: Shimano Tiagra, braze-on, road double · Rear derailleur: Shimano Tiagra, 10-speed, GS Cage · Crankset: FSA Gossamer Pro, forged aluminum, MegaExo, sub compact; chainrings: 48/32T w/chainguard · Bottom bracket: FSA MegaExo · Cassette: Shimano, 10-speed, 11-34t · 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: (F) Shimano Acera hydraulic disc, resin pads, 160mm rotor / (R) Shimano Acera hydraulic disc, resin pads, 160mm 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: Wheels: (F) Axis Elite Deep / (R) Axis Elite Deep · Front tire: Espoir Sport Reflect, 700x30mm, 60TPI, double BlackBelt protection · Rear tire: Espoir Sport Reflect, 700x30mm, 60TPI, double BlackBelt protection

• 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: Specialized, double-butted alloy, 9-degree backsweep, 31.8mm · Stem: Specialized Flowset, integrated, 3D forged alloy, 4-bolt, 12-degree rise, 31.8mm clamp · Seatpost: Alloy, 2-bolt, micro-adjust, 25mm offset, 27.2mm · Saddle: Canopy Comp, hollow Cr-Mo rails, 155mm · Pedals: Specialized Fitness platform, alloy

• 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.
