• 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.

• 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: Shifters: SHIMANO TIAGRA ST-4700, 2x10 SPEED DUAL CONTROL LEVER · Rear derailleur: SHIMANO TIAGRA RD-4700 SS DIRECT ATTACH · Crankset: PRAXIS ALBA M24 50/34T, MAX CHAINRING: 50/34T, CRANK ARM: 170mm · Bottom bracket: PRAXIS M24 · Cassette: SHIMANO CS-HG500 10-SPEED 11-34T · Chain: KMC X10-1

• 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.

• Check both cables and housings for corrosion, fraying or drag. Confirm each caliper releases cleanly, then inspect pad thickness, rotor wear and rotor alignment.
• 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: ALLOY DOUBLE WALLS 32H · Rims: ALLOY DOUBLE WALL FV H: 28.3 451X19.3 28H FOR TYRE 451-28/62 DISC · Hubs: F: ALLOY DISC BRAKE QR9x100mm 28H 6B / R: ALLOY DISC BRAKE QR9x135mm 28H 6B FOR SPROCKET · Front tire: SCHWALBE ONE 20"-1 1/8 (451-28) · Rear tire: SCHWALBE ONE 20"-1 1/8 (451-28)

• 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: ZERO STACK W/ CAGED BEARING, ZS 44/28.6 | ZS 44/30 · Handlebar: ENTITY SPORT, W: 420mm, BB: 31,8mm, D: 124mm, B: 80mm · Stem: ENTITY SPORT, EXT: 90mm, BB: 31.8mm, R/D: 7degree · Seatpost: ENTITY SPORT, 27,2 x 350mm · Saddle: ENTITY SADDLE · Pedals: PP PEDALS W/ PP CAGE

• 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.
