2022 Specialized Demo Expert

• 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: Aluminum · Fork: RockShox BoXXer Select 29, DH DebonAir spring, adjustable low-speed compression, adjustable rebound, short crown, 20x110mm thru-axle, 56mm 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: RockShox BoXXer Select 29, DH DebonAir spring, adjustable low-speed compression, adjustable rebound, short crown, 20x110mm thru-axle, 56mm offset, 200mm of travel · Rear shock: RockShox Super Deluxe Select Coil, 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 GX DH, trigger, 7-speed · Rear derailleur: SRAM GX DH, 7-speed, trigger · Crankset: DESCENDANT DH, DUB, alloy, Direct mount ring, 165mm; chainrings: 34T · Bottom bracket: SRAM DUB, 83mm · Cassette: SRAM GX DH, 7-speed, 11-24t · Chain: SRAM PC1110 w/ Powerlink™

• 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 RS, 4-piston caliper, hydraulic disc, 200mm / (R) SRAM Code RS, 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 · Hubs: (F) Alloy, sealed cartridge bearings, 20x110mm, 28h / (R) Alloy, sealed cartridge bearings, 12x148mm thru-axle, 32h · Front tire: Butcher, GRID GRAVITY casing, GRIPTON® T9 compound, 2Bliss Ready, 29x2.3" · Rear tire: Butcher, GRID GRAVITY casing, GRIPTON® T9 compound, 27.5x2.3"

• 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. 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.
• 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, 30mm rise, 800mm, 35mm clamp · Stem: Descendant 35mm Direct Mount Stem, 50mm length · Seatpost: Specialized, 6061 alloy, 2-bolt clamp, 0mm setback, 30.9mm · Saddle: Body Geometry Henge DH, hollow Cro-Mo 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.
• 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.
