• 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: FACT 9m carbon front chassis w/ Specialized M5 Aluminum rear end, 27.5 Trail Geometry, SWAT™ Door integration, PF30 BB, fully enclosed internal cable routing, 12x148mm dropouts, sealed cartridge bearing pivots, replaceable derailleur hanger, 150mm of travel · Fork: FOX 34 Performance 27.5, 44mm offset, 15x110mm thru-axle, 150mm of travel

• 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 34 Performance 27.5, 44mm offset, 15x110mm thru-axle, 150mm of travel · Rear shock: RockShox Monarch RT3, Rx Trail Tune, AUTOSAG, rebound and 3-position compression adjust, 197x48mm

• 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 GX Eagle, trigger, 12-speed · Rear derailleur: SRAM GX Eagle, 12-speed · Crankset: Truvativ Descendant, aluminum, Boost™ 148, 170mm crankarm, 30mm spindle; chainrings: 32T · Bottom bracket: PF30 · Cassette: SRAM GX Eagle, 12-speed, 10-50t · Chain: SRAM GX Eagle, 12-speed w/ PowerLock®

• 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 Guide R, hydraulic disc, organic pads, Guide S4 4-piston caliper, 200/180mm rotor / (R) SRAM Guide R, hydraulic disc, organic pads, Guide S4 4-piston caliper, 180/160mm rotor

• 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: Roval Traverse Carbon 27.5, hookless carbon, 30mm inner width, 24/28h, tubeless ready, hand-built · Hubs: (F) Specialized, sealed cartridge bearings, 15x110mm spacing, 24h / (R) Specialized, sealed cartridge bearings, 12x148mm thru-axle, 28h · Front tire: Butcher, GRID casing, Gripton compound, 2Bliss Ready, 27.5 x 2.6" · Rear tire: Butcher, GRID casing, Gripton compound, 2Bliss Ready, 27.5 x 2.6"

• Spin both wheels and watch for side-to-side and vertical movement. Check spoke tension, rim condition and hub play. Inspect the carbon rims closely for impact marks, cracks, delamination or damage around spoke holes and bead hooks.
• 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: Handlebar: Specialized Trail, 7050 alloy, 8-degree backsweep, 6-degree upsweep, 27mm rise, 780mm, 31.8mm clamp · Stem: Specialized Trail, 3D forged alloy, 4-bolt, 6-degree rise · Seatpost: Command Post IRcc, 12-position micro-height adjustable, alien head design, bottom mount cable routing, remote SRL lever, 30.9mm, S: 100mm, M/L/XL: 125mm of travel · Saddle: Body Geometry Henge Comp, hollow Cr-Mo rails, 143mm · Pedals: Specialized Platform, Cr-Mo, 9/16" spindle

• 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.
