How are bike chains measured?

The chain in use on modern bicycles has a 1⁄2 inch (12.7 mm) pitch, which is the distance from one pin center to another, ANSI standard #40, where the 4 in “#40” indicates the pitch of the chain in eighths of an inch; and is standard 606 (metric) #8, where the 8 indicates the pitch in sixteenths of an inch.

Are bike chains a standard size?

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.

What is a 3/32 bike chain?

3/32″ (0.094″, 2.30 mm) chain is used on derailer equipped bicycles that have more than 3 cogs at the rear. Even somewhat narrower chain, typically . 090″ or 2.29 mm between the inner plates, is used for derailer-equipped bicycles with 9 or more sprockets at the rear.

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

How do you measure chain width?

It is measured by measuring the distance between 3 links, then dividing it by two.

  1. Chain pitch is shown with green markers, though it is determined by measuring the distance between 3 adjacent pins (blue mark) and dividing it by two.
  2. Inner chain width, marked with blue arrows and lines.
  3. From left to right:

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 do you measure the width of a necklace?

Length is measured from top to bottom, including the clasp. Width is always measured at the widest point.

Are 10 and 11-speed chains the same?

The spacing between 11-speed chainring teeth centers is not narrower than on 10-speed chainrings. In some cases, it is even a bit wider on 11-speed. So your system will perform pretty much the same as it does now if you were to replace your 10-speed chainrings with 11-speed ones.

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.

Do SRAM chains work with Shimano?

Shimano and SRAM 11-speed chains are cross-compatible. If you have a Shimano 11-speed drivetrain, a SRAM chain will work fine and vice versa, however manufacturer’s recommend pairing your components for optimal performance.

Does chain length affect gear ratio?

It doesn’t matter how much longer the chain is. You pull that much more chain with a big gear. If you want three revolutions of the rear wheel, in 48/16 you have to pull 48 links of chain while in 36/12 you only pull 36. The ratio of angular movement was also off, updated.

What is the best single speed gear ratio?

If you’re just starting out on your adventure on a single speed or fixed gear bike, a gear ratio of around 2.7-2.8 will be ideal.

What chain should I use for single speed?

1/8″ chains are used exclusively for single speed setups.
