What happens if my bike chain is too long?
A chain that’s too long (loose) may cause dropped chains and/or inconsistent shifting — front and back shifting. A chain that’s too short (tight) can cause even bigger problems. BUT, things can go really bad … if it does shift and rips the derailleur off, damages the chain or bends gear teeth.
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 do I know my bike chain size?
Add the multiplied chainstay length, the divided number of teeth for the chainring and rear sprocket, and add 1 (or 2.5 cm). The result is the ideal chain length for your bike. For example, you’d add 32.5, 13, 7 and 1 to get 53.5. The length of the chain should be 53.5 inches or 135.89 cm.
What size is standard bicycle chain?
Chains come in 3⁄32 in (2.4 mm), 1⁄8 in (3.2 mm), 5⁄32 in (4.0 mm), or 3⁄16 in (4.8 mm) roller widths, the internal width between the inner plates. 1⁄8 in (3.2 mm) chains are typically used on bikes with a single rear sprocket: those with coaster brakes, hub gears, fixed gears such as track bicycles, or BMX bikes.
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.
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.
When should I shorten my bike chain?
Most of the time, you will inspect your chain to know whether it needs a replacement. You should count the links from the first pin to the last pin. You must ensure that the gap between the pins corresponds to 12 inches. If it extends to more than 12 ⅛ inches, it is time to replace your bike chain or shorten the chain.
Should I shorten my bike chain?
You either deliberately run the chain long enough to handle your mistakes in shifting (for big/big) or you don’t. You should have better shifting theoretically with a shorter chain, but if you shift big/big by accident you do have a problem.
What do you do if you cut your bike chain too short?
Registered. To make the chain the correct length, cut one link off the left-over piece of chain that you’ve cut off, buy a second (preferably rivet type) master link, fit them both to the “short” cut chain, and then fit that to the bike using the master link that came with the chain.
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 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.
Bicycle drive chain length 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.
No, all bicycle chains are not the same size. Size varies on the bike’s numbers of sprockets, speeds, the distance between the front chainring and rear cogs, and the number of teeth on them.
