• 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: 200 Series Alpha Aluminum, E2 tapered head tube, BB86.5, internal control routing, disc brake balanced post mount, 3S chain keeper, hidden fender mounts

• 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.

Archived: Group: Shimano 105 mix · Shifters: Shimano RS685 hydraulic, 11 speed · Rear derailleur: Shimano Ultegra · Crankset: FSA Energy Cross, 46/36 · Bottom bracket: BB86.5 · Rear cogs: Shimano 105, 11-28, 11 speed · Chain: Shimano 105

• 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 RS685 hydraulic disc, 160mm rotors

• 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: Bontrager Affinity Comp Tubeless Ready · Hubs: Bontrager, 15mm front · Front tire: Bontrager CX3 Team Issue, aramid bead, 120tpi, 700x32c

• 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.
• Confirm whether the bike is actually set up tubeless, whether both tires hold pressure, and when sealant and rim tape were last serviced.

Archived: Headset: FSA Integrated, sealed cartridge bearings, 1-1/8" top, 1.5" bottom · Handlebar: Bontrager Race Lite IsoZone, VR-CF, 31.8mm · Stem: Bontrager Elite, 31.8mm, 7 degree, w/Blendr computer & light mounts · Seatpost: Bontrager carbon, 2-bolt head, 27.2mm, 8mm offset · Saddle: Bontrager Paradigm R, hollow chromoly rails

• 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.
