• 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: BallisTec Carbon, SAVE, BB30-83 Ai, internal cable routing, flat mount disc, 12x142 thru-axle · Fork: BallisTec Carbon, 1-1/8” to 1.5” steerer, internal cable routing, 12x100mm thru-axle, 55mm OutFront offset · Carbon

• Inspect the frame in bright light, especially the head tube, bottom-bracket area, chainstays and clamped surfaces. Look for cracks, ripples, crushed sections or signs of impact.
• 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 GRX RX600 hydro disc · Rear derailleur: Shimano Ultegra RX · Crankset: Cannondale 1, BB30a w/ FSA ring, 40T · Bottom bracket: Cannondale Alloy PressFit30 · Rear cogs: Shimano 105, 11-34, 11-speed · Chain: Shimano HG601, 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: Shimano hydro disc, 160/160mm RT56 rotors

• Inspect pads, rotors, calipers and the complete cable or hose path. Both levers should feel consistent and both calipers should release without persistent rubbing.
• 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: CX 2.0, 28h front, 28h rear · Hubs: (F) Formula RX-512 12x100 / (R) Formula RX-142 12x142 · Front tire: Vittoria Terreno Mix TNT, 700 x 33c, tubeless ready · Rear tire: Vittoria Terreno Mix TNT, 700 x 33c, 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: SuperX, 1.5” lower to 1-1/8” upper w/ reducer, 25mm Alloy top cap · Handlebar: Cannondale 3, 6061 alloy, Compact · Stem: Cannondale 3, 6061 alloy, 7-degree · Seatpost: Cannondale 3, 6061 Alloy, 25.4 x 350mm (46-56), 400mm (58-61) · Saddle: Fabric Scoop Shallow 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.
• 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.
