Archived: Frame: ALX XC TRAIL FRAME · Fork: SUNTOUR XCM 120MM TRAVEL, QR 100MM

• 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: Shifters: SHIMANO, 9-SPEED TRIGGER · Rear derailleur: SHIMANO DIRECT ATTACH · Crankset: 32T · Bottom bracket: BSA THREADED 68/73MM · Cassette: SHIMANO, 11-46T · Chain: KMC CHAIN

• 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: SHIMANO MT200 HYDRAULIC DISC BRAKE; Levers: SHIMANO MT200 HYDRAULIC DISC BRAKE; Rotors: FRONT:180MM REAR:160MM CENTER-LOCK

• Squeeze each lever firmly. It should feel consistent and return cleanly. Check levers, hoses and calipers for fluid, inspect pad thickness and contamination, and examine rotors for wear or bending.

Archived: Wheels: ALLOY DOUBLE WALL · Rims: ALLOY DOUBLE WALL 584-15 32H FOR TYRE 584-35/68 · Hubs: F: ALLOY QRx100mm 32H CENTER LOCK / R: ALLOY BOOST QRx141mm 32H CENTER-LOCK · Front tire: PERFORMANCE TIRE 27.5"X2.25" · Rear tire: PERFORMANCE TIRE 27.5"X2.25"

• 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: THREADLESS ZERO STACK HEADSET, ZS 44/28.6 | ZS 56/30 · Handlebar: POLYGON SPORT, ALLOY · Stem: POLYGON SPORT, ALLOY · Seatpost: POLYGON SPORT, ALLOY · Saddle: VOID SADDLE · Pedals: ALLOY CAGE PEDAL W/ REFLECTOR

• 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.
