How long should a bicycle chain be?
Using a ruler, a new chain should measure exactly 12 inches across 12 links, from middle of pin to middle of pin. The number most commonly agreed on for a worn chain is one percent elongation between links.
How do I know if my chain is too long?
If the chain is really short, then you might not even be able to shift into the largest cog. Then, if you shift into the smallest chainring and smallest cog and if the rear derailleur pulls the chain back so far that it comes in contact with itself, the chain is too long.
What size bike chain do I need single speed?
1/8″ chains are used exclusively for single speed setups. In addition to the other answers, I found it helpful to read that the nominal width of a chain (1/8 or 3/32) actually refers to the width of the sprocket.
How do I know what speed my bike is?
Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.
What is a chain stay?
What is the chainstay? The chainstay or “stays” = The pair of frame tubes that joins the bottom bracket shell to the rear axle holders (the slots the back wheel goes in). This means that the chain stays connect the bottom bracket (BB) to the center of the back wheel.
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.
Do I need to shorten my bike chain?
Why Shorten a Bike Chain? All bikes come with a recommended bike chain length. It’s important to stick to this length if you want to ride comfortably and preserve the life of the rear derailleur. It’s the bike chain that does the work of getting the tires in rotation so that your bike can get in motion.
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.
Does chain length affect shifting?
Setup: Chain Length. Proper chain length makes a big difference with shifting. It’s not intuitive — that’s for sure — but lots of front shifting problems are solved by setting chain length (and tension) correctly.
Does Cage length affect chain length?
In short, the wrong length derailleur cage will make determining proper chain length nearly impossible. Too much chain length and you’ll have shifting issues and suffer from dropped chains, but too little could rip your bike’s derailleur right off.
