What is a narrow bike chain?

Narrow-wide chainrings have alternating narrow and wide teeth that fit into the inner and outer links respectively. This makes the chain more secure on the chainring and less likely to fall off. A narrow-wide ring is only necessary if you have a single chainring at the front and a rear derailleur.

Are there different size bike chains?

Chains come in 3⁄32 in (2.4 mm), 1⁄8 in (3.2 mm), 5⁄32 in (4.0 mm), or 3⁄16 in (4.8 mm) roller widths, the internal width between the inner plates. ⁄8 in (3.2 mm) chains are typically used on bikes with a single rear sprocket: those with coaster brakes, hub gears, fixed gears such as track bicycles, or BMX bikes.

Do I need a chain guide with narrow-wide?

But what if you’re a competitive enduro racer? Then you need as much chain retention as you can get: narrow-wide, clutch, and chain guide. For years MRP scoffed at the folks that said you didn’t need to run a chain guide with a 1x narrow-wide setup, but they kept selling them anyways.

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 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.

How do I know if my bike is 10 or 11 speed?

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 chain guides worth it?

Why You Should Run a Chain Guide

Mounting a chain guide on your mountain bike gives you an extra sense of security, hopefully ensuring that you won’t ever drop your chain. When you are flying through rough sections of trail, the chain will jump up and down and can sometimes work its way off the chainring.

When should I replace narrow-wide chainring?

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 if my bike chain is too short?

You should also see two slight bends at each jockey wheel of the rear derailleur. 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.

What size bike chain do I need single speed?

1/8″ chains are used exclusively for single speed setups. There is some confusion in these numbers because the actual width of a 1/8″ sprocket is typically 1/8″(3.175 mm) and the gap between the inner side plates of the chain must be slightly wider to fit over the teeth.

Modern bike chains are properly called ‘roller chains’, and consist of short cylindrical rollers held together by side links. The gaps between the rollers mesh with the teeth on a sprocket or chainring, to drive the transmission when turned.

What is chain width?

In traditional chain speak, “chain pitch” is the length along the chain between adjacent roller pin centers, and “chain width” is the inner spacing between link plates. Chain pitch on all bicycle chains is 1/2-inch, since the distance between the centers of the pair of rollers on the same link plate is half an inch.
