Are mountain 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.

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 MTB chain do I need?

If you are using a bike with a derailleur the number of cogs on the rear hub will determine the chain size you will need. They are always 3/32″ chains. You can get a 5/6/7-speed, 8-speed, 9-speed, or 10-speed chains.

Are all 9 speed chains the same?

Chain width is about 6.7 mm.

Front chainrings are less sensitive to the thickness of chain used. Otherwise, all the 9 speed chains will work well, regardless of the manufacturer: Campagnolo, SRAM and Shimano.

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 is 40 chain?

What size is standard bicycle chain?

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. 1⁄8 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.

How do you size a Shimano chain?

Here’s the easy way to set the chain length:

  1. Keep the bike on the ground to prevent the rear wheel from spinning.
  2. Start wrapping the end of the new chain at the 9 o’clock position on the largest cog of the cassette.
  3. Wrap the new chain around your largest chainring on your crank (For 1x setups it’s your only chainring).

What is a 3 32 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.

What is the difference between HG and IG chains?

The HG chain is a narrower chain meant for 8-9 speed drive trains. The IG chain is wider and meant for 6,7,8 speed drive trains.

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. In most situations, the set-up works.

Can I use 10 speed crankset with 9 speed chain?

The 10 speed chain rings will be fine with a 9 speed chain running on them. The problem you will have is the spacing between the chain rings. The 10 speed rings sit closer together than they do on the 9 speed.
