Chains need special Lubricants like ProTecta Oiler

Thursday, October 18th, 2007

Chain maintenance whether on a bicycle or motorbike is one of the most controversial subjects between mechanics. The major cause of chain “stretch” is wearing away of the metal where the rivet rotates inside of the bushing (or the “bushing part of the inside plate) as the chain links flex and straighten as the chain goes onto and off of the sprockets. Premature chain fatigue can be a real problem and effect gear shifting and performance.

Three Points of Chain Lubricaton

First one must be aware of the three points where a chain needs lubrication

  1. The rivets need to be lubricated where they move inside the inner links as the chain bends and straightens.
  2. The insides of the rollers need lubrication to let them revolve freely around the bushings as they engage and disengage in the sprocket teeth, which can cause accelerated sprocket wear.
  3. The surface where the outer side plates overlap the inner side plates can benefit from lubrication as well, although this contact surface is much more lightly loaded than the first two.
