• 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: All New Series 4 Alloy for Gen 5 CX Drive Unit, 160mm MultiTrac LT Suspension, Adjustable Headset & CS Length/Height, Integrated Battery/Charging Port, 148mm Rear Thru-Axle · Fork: RockShox Zeb Ultimate, 170mm Travel, 29", 110x15mm Maxle Stealth, 44mm Offset

• 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: Fork: RockShox Zeb Ultimate, 170mm Travel, 29", 110x15mm Maxle Stealth, 44mm Offset · Rear shock: RockShox Vivid Air Ultimate, 205x65, 30xM8 Lower Hardware, Custom Tune

• Inspect the fork stanchions for scratches or coating wear, look for oil or dirt rings at the seals, and cycle the fork through its travel while checking for binding or bushing play.
• Inspect the shock shaft and seals, cycle the rear suspension through its travel and check for oil, air loss, binding or unusual top-out and bottom-out noises.
• Hold the rear brake and load the suspension from several directions. Check pivots, bearings and mounting hardware for knock, looseness or side play.
• Ask for dated fork, shock and pivot-service records. A clean exterior does not establish the condition of internal seals, oil, bushings or bearings.

Archived: Shifters: SRAM AXS Pod Infinity Mount · Rear derailleur: SRAM GX AXS T-Type · Crankset: Sram GX, 34T, 150mm · Cassette: SRAM CS-XS-1275 T-Type, 10-52T · Chain: SRAM GX T-Type

• Confirm every shift battery charges and every control operates. Shift through the full cassette under light load while checking pairing, derailleur alignment and response at both ends of the range.
• 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 Maven Silver, 4-Piston Hydraulic Disc, HSC 200mm Rotor / (R) SRAM Maven Silver, 4-Piston Hydraulic Disc, HSC 200mm Rotor; Levers: SRAM Maven Silver

• 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: 29" · Rims: DT Swiss M552, 30mm Inner, 32H · Hubs: (F) DT Swiss 370 Hybrid, 110x15mm, 6-Bolt Disc, 32H / (R) DT Swiss 370 Hybrid, 148x12mm, 6-Bolt Disc, Mircro Spline Driver, 32H · Front tire: Schwalbe Magic Mary, Gravity Pro, Ultra Soft, Radial, 29x2.5" · Rear tire: Schwalbe Magic Mary, Gravity Pro, Soft, Radial, 27.5x2.5"

• 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. This record indicates different front and rear wheel diameters, so verify each tire at its correct end.
• 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: FSA Custom Headset, Adjustable HTA Design · Handlebar: PNW Range Handlebar, 38mm Rise, 35mm Clamp, 800mm Width · Stem: All New Marin CNC, 35mm Length, 35mm Bar Bore · Seatpost: PNW Loam Post with Range Lever, Size S=150, M=170mm Travel, Size L-XL 200mm Travel, 34.9mm · Saddle: WTB Devo Pick-Up

• 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.

• Inspect the battery case, mount, lock and electrical contacts for cracks, impact, corrosion, swelling, overheating marks or looseness. Confirm the battery charges normally.
• Confirm the correct charger, battery keys and removable system parts are included. Check charger cables and connectors for damage or improvised repairs.
• Power the system on from cold, check the display for warnings, and test every assist mode. Assistance should engage and stop predictably without intermittent cutouts or abnormal motor noise.
• Ask for available battery-health, cycle-count, diagnostic and firmware records. Confirm that replacement batteries and system support remain available before agreeing on value.

• 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.
