Archived: Frame: Welded aluminum · Fork: Girvin AL MCU · Aluminum, ovalized, Girvin Linkage 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: Girvin AL MCU · Rear shock: Girvin MCU, 3.5" 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: Shimano Deore XT/LX · Shifters: Grip Shift SRT-600 · Front derailleur: Shimano Deore LX, bottom-pull · Rear derailleur: Shimano Deore XT SGS · Crankset: Sugino Impel 500, 22/32/42 teeth · Bottom bracket: Shimano BB-UN51, 110 mm spindle · Rear cogs: 8-speed, 11 - 28 teeth · Chain: Sachs SC40, 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: Magura Hydraulic HS22 brakes, Magura Hydrostop levers

• 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: Wheel size: 26" wheels · Rims: Mavic 221, 32-hole · Front tire: 26 x 1.95" WTB Primal Raptor

• 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" Dia-Compe Kontak Aheadset AL · Handlebar: Hsin Lung alloy · Stem: Girvin Forged · Seatpost: Kalloy SP-258, 27.2 mm diameter · Saddle: Vetta SL · Pedals: Wellgo LU-940 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.
