• 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, 29” geometry, tapered headtube, PF30 BB, internal shift/brake routing, 142mm dropouts, PM 160 rear brake, replaceable alloy rear derailleur hanger · Fork: RockShox Reba RL 29, Solo Air spring, tapered alloy steerer, w/ lockout, compression, rebound adjust, 15mm thru-axle, S: 80mm travel, Others: 90mm · Suspension

• 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.

• 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.
• Ask for dated fork-service records. A clean exterior does not establish the condition of internal seals, oil or bushings.

Archived: Group: SRAM mix · Shifters: SRAM X7, 10-speed, w/ MatchMaker clamp · Front derailleur: SRAM X7, 10-speed, top pull · Rear derailleur: SRAM X9 Type 2, 10-speed, mid cage · Crankset: Custom SRAM S-1250, 7050 alloy arms, 10-speed XC double, PF30 spindle, 36/22, 104/64mm BCD spider · Bottom bracket: SRAM, PF30, OS press-in bearings, sealed cartridge · Rear cogs: SRAM PG 1030, 10-speed, 11-36 · Chain: SRAM PC 1031, 10-speed, w/ PowerLink, nickel finish

• 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: Magura MTS, hydraulic disc, Hi Friction pad, alloy master cylinder, alloy caliper, Storm SL rotor, S/M: 180mm rotor, Others: 160mm, Magura MTS, hydraulic disc, Hi Friction pad, alloy master cylinder, alloy caliper, 160mm Storm SL 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: Wheel size: 29 · Rims: Specialized Hi Lo disc, sealed cartridge bearings, 15mm thru-axle, 32h, Roval 29, alloy, 21mm inner width, 32h · Hubs: Specialized Hi Lo disc, 4 sealed cartridge bearings, 12mm thru-axle, 32h · Front tire: S-Works Fast Trak Control, 120TPI, 2Bliss Ready, folding bead, 29x2.2", Specialized Fast Trak Control, 60TPI, 2Bliss Ready, folding bead, 29x2.0"

• 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.

Archived: Headset: 1-1/8" and 1-1/2" threadless, Campy style upper with 1-1/2" lower, cartridge bearings · Handlebar: Specialized flat, 8-degree backsweep, 31.8mm · Stem: Specialized, forged alloy, 6-degree rise · Seatpost: Specialized alloy, single bolt, 27.2mm · Saddle: Body Geometry Phenom Comp, hollow Cr-Mo rails, 143mm · Pedals: Resin test ride, w/ toe clips, CEN std.

• 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.
