## How do I know what size chain I need for my bike?

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.

## 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.

## Will 11 speed chain work with 10 speed cassette?

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.

## 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.

## Is my bike chain too short?

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. Before you remove the chain, make sure it’s on the small chainring and smallest cog.

## Can I use a 9 speed chainring with a 10 speed chain?

[/quote]Two bikes with 10 speed chains running on ‘9’ speed TA rings, both absolutely fine. 9 and 10 speed rings have exactly the same width teeth AFAIK.

## What does 9 speed bike mean?

When magazines and websites talk about a bike’s ‘speed’, it’s a reference to the number of sprockets. A bike with three chainrings and nine sprockets is 9-speed, even though it has 27 theoretical ratios. The higher the sprocket count, the more expensive, smoother shifting, and lighter weight the gears.

## Can I convert my 8 speed bike to 10 speed?

Answer: No you don’t need a new hub. However, you will probably need to put a small (~1mm) spacer at the back of the cassette, otherwise you won’t be able to tighten the whole cassette down.

## Can I use an 11 speed crank on a 10 speed bike?

An 11-speed crank will perform equally well on a 10-speed system. No one has shown that there is any difference in ring spacing. The chains have the same internal width, so don’t know the difference.

## Are 10 and 11 speed chainrings the same?

There’s no meaningful difference between 10 and 11 speed rings. Instead of making the cogs narrower, Shimano thinned down the spacing between the plates of the chain.

## Are Shimano 10 and 11 speed compatibility?

A 10-speed Shimano or SRAM cassette can still be fitted to an 11-speed body, but a spacer will be required to make up for the difference in width. There is another, more subtle, incompatibility that affects different brands of hubs and wheels, but it will only have an impact on those riders using multiple wheelsets.
