Archived: Frame: TIG-welded · Fork: SR Suntour XCP75, 75mm travel · Aluminum, single 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 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.
• Ask for dated fork-service records. A clean exterior does not establish the condition of internal seals, oil or bushings.

Archived: Group: Mountain Mix · Shifters: Shimano ST-EF29 EZ Fire STI · Front derailleur: Suntour XCC-202 , top-pull/clamp-on · Rear derailleur: Shimano Deore · Crankset: Suntour XCC-250, 22/32/42 teeth · Rear cogs: 8-speed, 11 - 34 teeth · Chain: KMC IG-31, 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.

• 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: Weinmann aluminum double-wall, 32-hole · Hubs: Aluminum disc · Front tire: 26 x 2.10" Kenda Klaw XT

• 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 Ritchey · Handlebar: T:9 · Stem: Aluminum threadless · Seatpost: Aluminum micro-adjust · Saddle: WTB Speed She Sport · Pedals: Resin platform

• 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.
