Quick Answer: What Size Is Common 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 size is a 9 speed chain?

9 speeds. Chain width is about 6.7 mm. In a pinch, a 10 speed chain can be used. Still, narrower chain is more expensive, doesn’t last as long and will cause a bit slower shifting… but it will work.

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.

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 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.

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.

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 9 and 10-speed chains the same?

The internal/roller width of 9 and 10- speed chains is the same – 2.18mm. The only difference is the spacing of the chainrings. 9 and 10-speed chainrings aren’t spaced the same way, but the differences aren’t humongous.

Will 11 speed chain work with 10-speed?

As said above, the inside dimensions of a 10-speed and 11-speed chain are virtually identical, so there’s no problem running an 11-speed chain on 10-speed cogs. What’s narrower is the outside dimension of an 11-speed chain compared to a 10-speed chain.

What is an 11 speed chain?

Chains for 11-speed systems are around 5.4mm wide on the outside, vs. around 5.9mm wide for 10-speed ones, so that’s 0.25mm narrower from the center of the cog tooth to the end of the chain pin on each side.

Can you use Eagle chain 11 speed?

No, Eagle™ chains are not compatible with 11 -speed cassettes, derailleurs or rings.
