Archived: Frame: Welded aluminum · Fork: Girvin AL MCU · Aluminum, ovalized, Girvin Linkage crown

• 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.
• Inspect the fork crown, blades, dropouts and visible steerer area. Check that it is straight, securely installed and free of cracks or impact damage.

Archived: Fork: Girvin AL MCU · Rear shock: Girvin MCU, 3.5" travel

• 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 shock and pivot-service records. A clean exterior does not establish the condition of internal seals, oil, bushings or bearings.

Archived: Group: Shimano Deore XT · Shifters: Grip Shift SRT-800 X-Ray · Front derailleur: Shimano Deore XT, bottom-pull · Rear derailleur: Shimano Deore XT SGS · Crankset: Sugino Impel 500, 22/32/42 teeth · Bottom bracket: Shimano BB-UN51, 110 mm spindle · Rear cogs: 8-speed, 11 - 28 teeth · Chain: Sachs SC40, 1/2 x 3/32"

• 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 Deore LX M-System brakes, Dia-Compe PC-7N levers

• Inspect pads and braking surfaces, check the complete cable or hose path, and confirm both controls feel consistent and return cleanly.

Archived: Wheel size: 26" wheels · Rims: Mavic 220, 32-hole · Front tire: 26 x 2.10" WTB VelociRaptor kevlar

• 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.

• 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.
