• 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 Jekyll, 165mm travel, BallisTec Carbon front triangle, SmartForm C1 Alloy swingarm, carbon shock link, Ai offset drivetrain, ISCG05, PF30, flat mount brake, tapered headtube · Fork: Fox Float 36 Performance, 27.5, 170mm, 110x15, tapered steerer, 44mm offset

• Inspect composite areas in bright light for impact marks, cracks, ripples or crushed clamp zones. Check metal sections and welds separately for dents or cracking.
• 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: Fox Float 36 Performance, 27.5, 170mm, 110x15, tapered steerer, 44mm offset · Rear shock: Fox Float Performance DPS EVOL w/ Gemini remote-actuated dual mode air spring system, Flow Mode - 165mm / Hustle Mode - 130mm

• 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: Shimano SLX, 11-speed · Rear derailleur: Shimano XT, 11-speed Shadow Plus · Crankset: Cannondale Si, BB30, SpideRing 30T, Ai offset · Bottom bracket: Cannondale Alloy PressFit30 · Rear cogs: Shimano XT, 11-speed, 11-46 · 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 SLX hydro disc, 203/180mm

• 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: 27.5" · Rims: WTB Frequency Race i29, 29mm inner, TCS Tubeless Ready 27.5”, 32h · Hubs: Formula w/ HG driver - 110x15 thru front / 148x12 thru rear w/Ai offset · Front tire: Maxxis Minion DHF 27.5x2.5” front, DHR II 2.4” rear, Dual Compound, folding, Tubeless Ready · Rear tire: Maxxis Minion DHF 27.5x2.5” front, DHR II 2.4” rear, Dual Compound, folding, 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: Integrated, 1-1/8 to 1.5”, sealed angular contact bearings · Handlebar: Cannondale C3 Riser, 6061 Alloy, 15mm rise, 4° up, 9° back, 31.8, 780mm · Stem: Cannondale C3, 6061 Alloy, 1-1/8”, 31.8, 0°, 35mm · Seatpost: TransX dropper, Internal Routing, 31.6, 120mm drop · Saddle: Fabric Radius Scoop

• 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.
