1998 Marin Alpine Trail F.R.S.

Archived: Frame: TIG-welded · Fork: RST 381RM · Aluminum/chromoly, 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.
• 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: RST 381RM · Rear shock: Shock Works, 4.0" 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: Mountain Mix · Shifters: Shimano STX-RC RapidFire SL · Front derailleur: Shimano STX-RC top-swing, bottom-pull/clamp-on 35.0mm · Rear derailleur: Shimano STX-RC · Crankset: Shimano STX, 22/32/42 teeth · Bottom bracket: Shimano BB-UN52, 110mm spindle · Rear cogs: 8-speed, 11 - 28 teeth · Chain: Shimano CN-IG51, 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: Dia-Compe VC-737 brakes, Dia-Compe DP-7 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 X138, 32-hole · Hubs: Front: Shimano STX, Rear: Shimano STX-RC · Front tire: 26 x 1.95" IRC Mythos XC 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.

Archived: Headset: 1 1/8" threadless Dia-Tech steel · Handlebar: Aluminum, 1" rise · Stem: Marin Lite aluminum · Seatpost: Marin Lite Comp, 30.0mm diameter · Saddle: Ritchey Vector · Pedals: Aluminum cage w/clips & straps

• 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.
