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.
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.
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.
Are all bicycle chains the same size?
Are all bicycle chains the same size? 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.
How do I know my roller chain size?
Roller Chain Identification Most roller chain has the size stamped right into the side plates. You may see something like “40”, “C2080H” or “10B” stamped in, which the industry number that represents the chain size. Old chains will most likely need to be cleaned in order to see the size.
How do I find my anchor chain?
Anchor chain is measured in two primary ways – thickness of the metal in the link, and the length of the link. The most precise method is to use Vernier calipers, though with care a measuring tape can get a close enough estimate.
How do you work out the length of chain between two sprockets?
Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.
