How do I know what speed my bike chain 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.

How do I know what speed my chain is?

It mainly includes the sizing of inner and outer width along with size charts. For example, single-speed chains have standard 1/8 inches width, while multi-speed chains with 5-8 speeds have an inner width of 3/32 inches. Bikes with 9-12 speeds have 11/128 inches inner width.

How do I know which chain to buy for my bike?

How do I choose? Bike chain selection is firstly decided based upon the “speed” of the chain; this is because it determines the width of the chain. An 11 speed chain for example is narrower than a 9 speed chain, as the sprockets on the 11 speed cassette have a narrower spacing between them.

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. … Going further narrower, like a 10, or 11 speed chain on an 8 speed cassette can and often does work.

What do the numbers on a bike chain mean?

Chain size is in inches, the three digit number used to describe the chain size is based on the “rule of eights”. The first digit is for chain pitch. This is the distance between the pins. The second and third digits combine for roller width, with a decimal point inserted between the second and third digits.

Are bike chains universal?

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.

Will a 10 speed chain work on a 8 speed cassette?

A 10 speed chain should work on an 8-speed drivetrain. if you want 10 speeds, you will need a 10 speed-specific chain, cassette, derailleur and shifter (and a new cable while you’re at it).

Can I use a 8 speed chain on a 9 speed cassette?

The 9 speed chain is thinner than the 8 speed which suggest the 9 speed cassette has thinner teeth. No, no problems, it works fine. The cogs on 9sp and 8sp are the same thickness, the difference is the thickness of the spacers between them.

Can I use 10-speed chain on 11-speed cassette?

A 10-speed chain will be too wide for an 11-speed cassette. It will cause rubbing, poor shifting, and premature wear of the drivetrain. To increase the drivetrain’s lifespan and ensure smooth shifting, it’s recommended to stay away from this combination.

Can I use a 9 speed chain on a 7 speed cassette?

A chain wider than standard will not fit between adjacent sprockets of a freewheel or cassette, though it usually poses no problem in a derailerless system. … Thus, you can use a “9-speed” chain with a 7-speed or 8-speed system, or a “10-speed” chain with a 9-speed system.

Are 8 and 9 speed chains the same?

7, 8, and 9 speed chains have the same inner width, but 9 speed chains have thinner outer plates for a thinner overall chain. So while a 9 speed chain works fine on a 7 or 8 speed drivetrain, it will be a weaker chain that tends to “stretch” faster.

Are 11 and 12-speed chains the same?

This is accomplished by making the outer links of the chain thinner. … Ultimately, single-speed chains are the strongest because they can be very thick since there’s only one cog at the back. The width of a 12-speed chain is roughly 5.25mm whereas that of an 11-speed chain is 5.62mm. That’s a 0.37mm difference.

How many links should a 8 speed chain have?

Generally 6-7-8 speed chains are the same and 9 speed are thinner, more than 9 speed is a bit specialized. The length isn’t as important because you will usually have to shorten the chain to fit your bike. The standard chain is 114 pins (56 links) but you almost never need to know this ( I had to look it up!). Aha.

What’s the difference between 520 and 525 chains?

It may sound ridiculous, but by simply changing your regular 525/530 chain and sprockets to a 520, you’ll gain roughly 1.5hp on the dyno and save nearly a kilogram. … People will bring up the fact that 520 chains will wear out faster than 525/530 chains. Ultimately, if you start to nitpick, yes, they will.

How many links should my chain have?

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.
