FAQ: What Number Chain Size Is Standard Bicycle Chain?

What size is a standard bicycle chain?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.

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 number chain is a bike chain?

Bicycle Chains are generally categorized into two types: 1/2 × 1/8 and 1/2 × 3/32. The first number (1/2) is the chain pitch; the latter numbers (1/8 and 3/32, respectively) indicate the inner width in inches.

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.

What is a bicycle chain link?

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.

How is chain wear measured?

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 often should I change my bike chain?

The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same. 4

Are 6 7 8 speed chains the same?

5, 6, 7 and 8 speed chains Shimano, SRAM and Campagnolo all use the same chain with 8 speeds. Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm.

What are the different types of chain?

Different Types of Chain

  • Box Chain. This chain is made up of wide square-shaped links and creates a smooth appearance.
  • Cable Chain. Also known as a link chain, this chain is comprised of oval or round links of the same size.
  • Curb Chain.
  • Figaro Chain.
  • Infinity Link Chain.
  • Rollo Chain.
  • Rope Chain.

Are 11 and 12 speed chains the same?

12-speed chains can operate just fine with 11-speed cassettes. The main exception are Shimano’s new 12-speed HG+ models which are heavily optimized for downshifting and thus come with custom inner plates that don’t mix well with non-Shimano 12-speed components.

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.
