1997 ProFlex 757

Archived: Frame: TIG-welded · Fork: Girvin Cross-Link w/Noleen NR-1 · Aluminum, Girvin Linkage crown

• Inspect the complete frame for cracks, dents, distortion, heavy abrasion, suspicious paint differences or evidence of a previous repair.
• 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 Cross-Link w/Noleen NR-1 · Rear shock: Noleen NR-1, 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: Shimano Deore LX · Shifters: Shimano Deore LX RapidFire SL · Front derailleur: Shimano Deore LX top-swing, bottom-pull/clamp-on 31.8 mm · Rear derailleur: Shimano Deore LX SGS · Crankset: Shimano Deore LX, 22/32/42 teeth · Bottom bracket: Shimano BB-UN52, 110 mm spindle · Rear cogs: 8-speed, 11 - 30 teeth · Chain: Sachs SC-40, 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: Shimano Deore LX V-Brake brakes, Shimano Deore LX levers

• Inspect pads, cables and housings, then examine both rim braking surfaces for concavity, cracking or heavy wear. Confirm each caliper returns and centers correctly.

Archived: Wheel size: 26" wheels · Rims: Mavic 238, 32-hole · Hubs: Shimano Deore LX · Front tire: 26 x 2.10" Panaracer Duster II 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-Compe Kontak Aheadset AL-2 · Handlebar: Titec Enduro · Stem: Girvin Reversible forged · Seatpost: Polygon PM-312, 27.2 mm diameter · Saddle: Selle San Marco Tecno Dynamica · Pedals: Proflex Mag-C (clipless)

• 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.
