  • Non-round chainrings can sometimes cause problems in front shifting.
  • Most current mountain bicycles have three front chainrings; road bicycles may have two or three.
  • This is done because chain is shifted across the cassette much more often than the chainrings.
  • This is particularly of importance on steep climbs, when one would use the smaller chainrings.
  • The rear crankset typically has many chainrings, sometimes on both sides.
  • Otherwise, the relatively lighter and less expensive two chainrings may be better.
  • Cranks designed to mount one or two chainrings will almost always use a single bolt circle diameter.
  • The stepped chainrings are also quite evident, as the larger off-road ring is nearly twice the diameter of the road ring.
  • Typical cross country mountain bikes with three front chainrings will use a long cage rear derailleur.
  • This style is commonly found on racing bicycles with two chainrings.
  • The drive chain chainrings can be single gear or use a derailleur.
  • Compact gearing usually has a large percentage jump between the two chainrings.
  • If the chain has worn beyond this limit, the rear sprockets are also likely to wear, in extreme cases followed by the front chainrings.
  • There may be a second set of chainrings, often on the opposite side from the regular drive train, one on each crank set and connected by a separate chain.
  • More expensive sets have the chainrings bolted on so that they can be replaced if worn or damaged, or to provide different gearing.
  • The more common configurations have specific names which are usually related to the relative step sizes between the front chainrings and the rear cogset.
  • Some chainrings can be outfitted with a chain guard -- a plastic or metal ring slightly larger in diameter than the chainring.
  • This general arrangement is suitable for touring with most gear changes being made using the rear derailleur and occasional fine tuning using the two large chainrings.
  • Compact chainrings have been the dominant standard for mountain bike cranks since the mid nineties.
  • This gives the design a significant amount of anti-squat when pedaling in smaller chainrings, which helps reduce loss of energy due to squat.
