Monthly Bicycle Maintenance

I found these on TotalBike.com

Chain — Use the “12 links equals 12 inchesâ€Â? rule. Measurements of 12 1/8â€Â?+ are grounds for replacement. Use one of our chain wear indicators for a precise measurement. A worn chain will quickly wear your chainrings and cassettes.

Chainrings/Cogs — Inspect for straightness, bad teeth or small chips. Excessive chain suck with a new chain usually indicates that you need a new chainring. Check chainring bolts for tightness using a torque wrench for accuracy. Do not overtighten.

Crank/Bottom Bracket — Check for looseness/smoothness. Remove the chain and spin the cranks around. They should spin freely. If tightening crank bolts doesn’t solve the problem, rework bottom bracket (cartridge or cup-and-seal).

Handlebar — Check for bending or looseness. If it’s bent or if there is any indications of cracks or stress areas, replace it.

Pedals — Check for axle play by wiggling the pedal. Clean and repack bearings once a year at least. Tighten clips and check straps/clips for excessive wear. Clipless folks check release entities for wear/lubrication.

Saddle/Seatpost — Look for saddle rail deformities or cuts in the upholstered material. Lube seatpost liberally with white lithium grease for proper operation. Use electrical tape on small tears.

Wheels — Check rims for cracks, dings, dents, loose or broken spokes or other deformity. True wheels-if you can’t do it yourself, take it to a shop-a trued wheel is a strong wheel. Check hub bearings for smoothness/lack of play.
