• 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: Group: Shimano RD-TY300 rear and Shimano FD-TY510 top swing front · Shifters: Shimano EZ-Fire Plus ST-EF500 shifters, 21-speed · Front derailleur: Shimano RD-TY300 rear and Shimano FD-TY510 top swing front · Rear derailleur: Shimano RD-TY300 rear and Shimano FD-TY510 top swing front · Crankset: Forged alloy, 48/38/28T, 170mm with chain guard · Bottom bracket: VP sealed cartridge, 68 x 122.5mm · Cassette: Shimano CS-HG200, 7-speed 12-32T · Chain: KMC Z51

• 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: Promax TX-121 linear-pull with front power modulator and Shimano levers

• Inspect pads, cables and housings, then examine both rim braking surfaces for concavity, cracking or heavy wear. Confirm each caliper returns and centers correctly.
• 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: Double wall alloy rims, 32H, alloy hubs with QR and 14g spokes · Front tire: Kenda Eurotrek K-197, 700 x 35c · Rear tire: Kenda Eurotrek K-197, 700 x 35c

• 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: Internal cup threaded, 1 1/8” · Handlebar: Jamis Riser bar, aluminum, 25.4 x 10 ̊ sweep x 40mm rise x 600mm · Stem: Jamis alloy hi-rise, quill type, 35 ̊ rise, 80mm extension, 180mm high, 150mm (14-16”), 180mm (18”) · Seatpost: Jamis alloy micro-adjust, 27.2 x 350mm, alloy clamp with QR seatpin · Saddle: NEW Jamis Touring Women’s with SL cover · Pedals: Platform style, steel cage/resin body

• 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.
