How long is the average bike chain?
A new bicycle chain usually comes with 116 links. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings. So for optimal length a new chain is usually shortened from the 116 links that come in the box.
How do I know if my chain is too short?
You should also see two slight bends at each jockey wheel of the rear derailleur. If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog.
How can I tell if my bike chain is stretched?
Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.
How tight should a single speed bike chain be?
Chain Tension There should be approximately one half inch of movement in the chain up and down at a point half way between the front and rear sprockets. To change the tension loosen one of the axle-nuts and move the wheel forward or backward slightly and snug it up again.
Can I use an 8 speed chain on a single speed bike?
Since single speed chain is by far the cheapest, there is no need to experiment with multi speed chains. However, 6 to 8 speed chains can fit some single speed bicycles – depending on the chainring width.
Chain Link Sizes: How to Measure Chain Link Sizes
- Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line.
- Determine your side plate height and thickness by measuring both inside and outside the roller chain to ensure that you’re seeing a good average size.
Should I shorten my chain?
1 Answer. ” Never run with a chain that is too short, except in an emergency.” (from Sheldon Brown’s Derailleur Adjustment page). If a short chain ends up on the big chainring and big sprocket at the same time, then the derailleur will probably get damaged.
