2006 GT Double Down

Archived: Frame: TIG-welded · Fork: Custom designed dual crown chopper fork · Aluminum/magnesium

• 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: Crankset: AA chrome plated tubular crankset with Kustom Kruiser laser etched logo, Maltese Cross 5mm thick CNC cut one piece heat tre teeth · Bottom bracket: European size sealed cartridge bearing · Rear cogs: 1-speed, 22 teeth · Chain: Chrome Plated 3/32 with heat treated links

• Check chain tension and chainline, rotate the drivetrain through a full revolution and confirm the rear axle or tensioning hardware cannot slip.
• 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: Tektro IO cable actuated disc brake with custom CP rotor front/Shimano coaster rear brakes, Kustom Kruiser forged levers

• Check both cables and housings for corrosion, fraying or drag. Confirm each caliper releases cleanly, then inspect pad thickness, rotor wear and rotor alignment.

• 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.
