## How do I know my bike chain size?

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.

## 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.

## Are 7 and 8 speed chains the same?

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. That is why the reverse is not the case and a 7 speed chain and especially a 6 speed one will not work as well on an 8 speed system.

## 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 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.

## 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.

## 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 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

## 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.

## Are KMC chains better than Shimano?

The difference between the Shimano chain and the KMC is marginal; your choice will always come to personal preference. Despite the inconvenience of adjusting the chain, the Shimano runs a lot smoother and will provide you with long-lasting use.

## Will a 9 speed chain fit 8 speed?

9 speed chain on an 8 speed cassette is just fine; it’s the wider 8 speed which won’t fit the sprocket spacing on a 9 speed cassette.

## Can I replace a 7 speed freewheel with an 8 speed?

You can change to 8 speed, but a normal rear wheel for roadbikes will not fit directly into the frame because it’s 130 mm wide. Depends on the stiffness of the rear frame if it can be pushed together safely to 130 mm.

## 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.

## Can you use Eagle chain 11 speed?

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

## 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.
