• 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: Topstone, SmartForm C2 Alloy, 142x12 thru-axle, tapered headtube, flat mount rear brake, internal cable routing · Fork: Cannondale Topstone Disc, Full Carbon, 1-1/4” to 1-1/8” tapered steerer, 55mm offset, flat mount, 12x100 thru axle · Carbon

• 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: SRAM Apex 1 HRD, 1x11 · Rear derailleur: SRAM Apex 1, Long cage · Crankset: SRAM Apex Alloy, 40T · Bottom bracket: SRAM GXP · Rear cogs: SRAM PG-1130, 11-42, 11-speed · Chain: SRAM PC-1110, 11-speed

• 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: SRAM Apex 1 HRD, 160/160mm Centerline

• Inspect pads and braking surfaces, check the complete cable or hose path, and confirm both controls feel consistent and return cleanly.
• 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: WTB ST i23 Light TCS, 28h, tubeless ready · Hubs: Formula RX-512 12x100 front, RX-142 12x142 rear · Front tire: WTB Nano TCS, 700 x 40c, tubeless ready · Rear tire: WTB Nano TCS, 700 x 40c, tubeless ready

• 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: Topstone Si, 25mm Alloy top cap · Handlebar: Cannondale C3, butted 6061 Alloy, 16 deg flare drop · Stem: Cannondale C3, 6061 Alloy, 31.8, 7° · Seatpost: TranzX Dropper Seatpost, 50mm travel, 27.2 x 365mm, internal routing, drop bar remote · Saddle: Fabric Scoop Radius Sport, steel rails · Pedals: Not Included

• 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.
• Cycle the dropper post repeatedly. It should reach full travel, remain extended under load and have no unusual oil, excessive rotational play or damaged remote, cable, hose or battery.

• 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.
