• 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: M5 alloy, Style-Specific DH Geometry, BSA threaded BB, full internal cable routing with option for full external brake, 148mm rear spacing, sealed cartridge bearing pivots, replaceable derailleur hanger, 200mm of travel · Fork: Öhlins DH 29, Twin-Tube design, air spring w/ adjustable 3rd chamber, adjustable high- & low-speed compression, adjustable rebound, 20x110mm thru-axle, 58mm offset, 200mm of travel

• 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: Öhlins DH 29, Twin-Tube design, air spring w/ adjustable 3rd chamber, adjustable high- & low-speed compression, adjustable rebound, 20x110mm thru-axle, 58mm offset, 200mm of travel · Rear shock: Öhlins TTX, Twin-Tube design, high- & low-speed compression adjust, external rebound adjust, Trunnion mount, 225x75

• 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 X01 DH, trigger, 7-speed · Rear derailleur: SRAM X01 DH, 7-speed, trigger · Crankset: SRAM X01 DH, DUB, carbon, Direct mount ring, 165mm; chainrings: Steel, 30T · Bottom bracket: SRAM DUB, 83mm · Cassette: SRAM X01 DH, 7-speed, 10-24t · Chain: Sram PC1130 w/ Powerlink, 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: (F) SRAM Code RSC, 4-piston caliper, hydraulic disc, 200mm / (R) SRAM Code RSC, 4-piston caliper, hydraulic disc, 200mm

• 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 29" Alloy DH, 28mm internal width, 28h, tubeless ready · Front tire: Butcher BLCK DMND, 2Bliss Ready, 29x2.6" · Rear tire: Butcher BLCK DMND, 2Bliss Ready, 29x2.3"

• 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: Handlebar: Specialized DH, FACT carbon, 6-degree upsweep, 8-degree backsweep, 27mm rise, 800mm, 31.8mm · Stem: Specialized Direct Mount DH Stem, two-piece, forged alloy, 45mm · Seatpost: Thomson, alloy, straight, 12-degree clamp · Saddle: Body Geometry Henge DH, hollow titanium rails, 130mm

• 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. Look particularly closely for crushing, scoring or cracks at carbon handlebar clamp areas.
• 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.
