The bike measures 16-3/8″ from the center of the rear axle to the center of the crank bolt. The decimal equivalent for 16-3/8″ is 16.375 inches.
One link is two pin-to-pin dimensions. Each pin is 1/2″ from its neighbor, so a full link is 1″ long. When they say the chain is 116 links, they are really saying there are 116 pins, for a chain length of 58 inches.
The bike measures 16-3/8″ from the center of the rear axle to the center of the crank bolt. The decimal equivalent for 16-3/8″ is 16.375 inches. In the example above, this becomes 32.75 + 10.5 + 8 + 1 = 52.25 inches. Chains cannot be joined at 52.25 inches, so this length is rounded to 52 inches.
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.
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.
In US customary units modern definition, the link is exactly 66⁄100 of a US survey foot, or exactly 7.92 inches or approximately 20.12 cm. The unit is based on Gunter’s chain, a metal chain 66 feet long with 100 links, that was formerly used in land surveying.
What is the difference between bicycle chains?
Chains can vary in side plate shape, sizing, and height. Differences can cause variations in shifting performance between brands and models. Additionally, chains will vary in the quality of steel used. Better chains that are more durable and longer lasting tend to have harder rivets.
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.
Is my bike chain too short?
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. Before you remove the chain, make sure it’s on the small chainring and smallest cog.
The master link is a single removable link segment of a bicycle chain. You’ll hear people also refer to these as quick links. Also, SRAM’s version of the master link is called a Power Link. It is sold separately as well as typically included when you buy a SRAM chain.
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.
