2004 Marin Alpine Trail

Archived: Frame: TIG-welded · Fork: Answer Manitou Axel Comp, 70/100 mm travel · Single

• 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 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 Alivio RapidFire · Front derailleur: Shimano Alivio · Rear derailleur: Shimano Deore · Crankset: TruVativ Five-D, 22/32/44 teeth · Bottom bracket: TruVativ ISIS cartridge · Rear cogs: 8-speed, 11 - 28 teeth · Chain: Shimano CN-IG31

• 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: Hayes HMX-2 Mechanical Disc brakes, Pro 3 finger 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.

Archived: Wheel size: 26" wheels · Rims: Alex TA-19, 32-hole · Hubs: Front: Shimano Disc 32, Rear: Shimano disc · Front tire: 26 x 2.25" IRC Back Country

• 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: 1 1/8" threadless WTB Momentum Comp ST · Handlebar: Double Butted Alloy w/1" Rise · Stem: Cold Forged Threadless with 6 rise · Seatpost: Comp Alloy Micro Adjust · Saddle: WTB Speed-V ATB · Pedals: Composite with alloy cage

• 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.
