2001 Kona DuDu

Archived: Frame: TIG-welded · Fork: Marzocchi Z3 QR20 plus, 4.0" travel · Aluminum, triple-clamp 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.

Archived: Fork: Marzocchi Z3 QR20 plus, 4.0" travel · Rear shock: Fox Vanilla R, 4.0" travel

• 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: Group: Mountain Mix · Shifters: Shimano Deore LX RapidFire SL · Front derailleur: Mr. Dirt Gizmo, chain retention device · Rear derailleur: Shimano Deore XT · Crankset: TruVativ Hussefelt DH, 38 teeth · Bottom bracket: TruVativ Hollow Splined · Rear cogs: 9-speed, 11 - 28 teeth · Chain: Shimano CN-HG72, 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: Avid Arch Rival brakes, Avid Speed Dial 5 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 F519 · Hubs: Front: King Kong QR 20 disc, Rear: Shimano M555 disc · Front tire: 26 x 2.10" Tioga Factory DH

• 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.

Archived: Headset: Aheadset SX-1 · Handlebar: Kona DH Primo Aluminum Riser · Stem: Funn Serial Rippa · Seatpost: IRD Quad 2 · Saddle: SDG Grand Prix Kevlar · Pedals: Wellgo Slalom

• 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.
