# Are 8 Speed Bike Chains Wider Than 9 Speed

Table of Contents

## Will an 8 speed chain work on a 9 speed chainset?

Yep, it’ll be absolutely fine. Should work fine, the differenec in width of an eight and nine speed chain is minimal. You may have a problem with the chain not seating on the chainrings. Chains, sprockets and chainrings all wear at the same rate, if you replace one of these items there is a chance they just wont ‘fit’.

## Can I use a 9 speed chain on an 8 speed bike?

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 any 8 speed cassette?

Condensed Answer: Shimano and SRAM 10-speed cassettes can be installed on 8-speed hubs because 8,9 and 10-speed cassettes have similar widths. However, a Campagnolo 10-speed cassette won’t fit on an original 8-speed hub due to incompatible spline designs.

## Will a 9 speed crank work with 8 speed?

Yes, there are no complications with running a 9 speed crankset on an 8 speed drivetrain.

## 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).

## What is the difference between bike chains?

Differences can cause variations in shifting performance between brands and models. Additionally, chains will vary in the quality of steel used. Better chains that are more durable and longer lasting tend to have harder rivets. Riding a bike tends to wear and thin the rivet as it is pulled against the inner plates.

## Can I use a 12 speed chain on a 9 speed cassette?

Using an 11 or 12 speed chain on a 9 speed cassette will present problems with smooth shifting and the big danger would be risk of severe chain jam should the thinner profile chain of 11 or 12 speeds get stuck between cogs of a 9 speed cassette which are spaced wider than an 11 or 12 speed cassette’s cogs.

## Can you put an 8 speed cassette on a 7 speed hub?

7-speed hubs won’t normally accept 8-, 9- or 10 speed cassettes without modification. Click here for details. 7-speed cassettes fit fine on 8- and 9-speed (and most 10-speed) hubs if you put a 4.5 mm spacer onto the body before the cassette. Click here for details.

## What size is a 9 speed chain?

Single speed chains have inner width of 1/8″ (3.175 mm). Multi speed chains, from 5 to 8 have inner width of 3/32″ (2.38 mm). Multi speed chains from 9 to 12 speeds have inner width of 11/128″ (2.18 mm). “Exotic” standard for freight bicycles is 5/32″ (4 mm).

## Are all 9 speed chains the same?

Chains for 9-Speed Drivetrains are 6.7mm wide and work well regardless of manufacturer; Shimano, SRAM and Campagnolo. Front chainrings are less sensitive to the width of a chain, therefore SRAM 9-speed drivetrains can even use 10-speed chains.

## How do I know my bike chain size?

Add the multiplied chainstay length, the divided number of teeth for the chainring and rear sprocket, and add 1 (or 2.5 cm). The result is the ideal chain length for your bike. For example, you’d add 32.5, 13, 7 and 1 to get 53.5. The length of the chain should be 53.5 inches or 135.89 cm.

## Can I change my 8 speed to a 10-speed?

Therefore, it is possible to convert an 8-speed wheel to a 10-speed wheel by adjusting the height with a commercially available Shimano 1.0mm low spacer on the low side.

## Can I make a 8 speed bike to 10-speed?

Yes, it will fit fine. 8,9,10spd freehubs are the same. If it’s road you’re talking about then you’ll need a 1mm spacer behind the cassette if it’s Shimano, if it’s MTB then it’ll go straight on.

## Are Shimano 8 speed cassettes interchangeable?

SRAM and Shimano are the same spacing and fit the same freehub, all 8 speed chains are compatible.

## Which is longer 10 speed or 9 speed chain?

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.
