• 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: Series 3 Double Butted CrMo, Size-Specific Wheels (XS, S = 650B, M, L, XL = 700C) , Biometric Geometry, Fender and Rack Mounts, Thru-Axle, Flat Mount 160 Disc Mount · Fork: Series 3 CrMo, Thru-Axle, Flat Mount 160 Disc Mount, Fender, Rack, and Bottle Cage Eyelets

• Check paint damage, vent holes and accessible internal surfaces for corrosion. Look for dents, bent tubes and cracking around welded or brazed joints.
• 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 1x12-Speed · Rear derailleur: SRAM Apex 1 12-Speed · Crankset: SRAM Apex 1, 40T · Bottom bracket: SRAM DUB BSA · Cassette: SRAM CS-XG-1275, 10-52T · Chain: SRAM NX

• 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: (F) SRAM Apex 1 Flat-Mount Hydraulic Disc, 160mm Rotor / (R) SRAM Apex 1 Flat-Mount Hydraulic Disc, 160mm Rotor; Levers: SRAM Apex 1 w/ Integrated Shifter

• 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: Rims: Marin Aluminum Double Wall, 25mm Inner, Disc Specific, Tubeless-Compatible · Hubs: (F) Forged Aluminum Alloy, Disc, 32H / (R) Forged Aluminum Alloy, Disc, 32H · Front tire: Vee Tire Co., QuikStyk, 700x45, Folding Bead, Tubeless Compatible · Rear tire: Vee Tire Co., QuikStyk, 700x45, Folding Bead, Tubeless Compatible

• 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 No.8B · Handlebar: Marin Butted Alloy, Compact 16º Flared Drop · Stem: Marin 3D Forged Alloy · Seatpost: Marin Alloy, 27.2mm · Saddle: Marin Beyond Road Concept · Pedals: Nylon Platform

• 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.
