Are 9 And 10-speed Cassettes The Same Width? Therefore, a 10-speed chain happens to be thinner than a 9-speed and can work impeccably well with a 9-speed gear. The data above shows that the spacer widths reduce as you install a higher number of gears. All the same, the spacer width gradually reduces with an increase in the number of cogs. This feature ensures that there is no compromise on the sprocket’s width. Notably, a 10-speed chain has equal inner roller widths with 9-speed chains. Therefore a chain meant for more gears are narrower and will work perfectly with a 9speed cassette without rubbing against the cogs or skipping. So actually, when you have to stack more cogs on the same hub, you need to condense the cassette. Generally, a 10-speed chain is slimmer and lighter than a 9-speed. Will 10-speed Chain Work On 9-speed Cassette? However, if your bike has a 9-speed cassette with narrow spacing between the cogs, a 9-speed chain could come off the cog while riding.Īll the same, a 10-speed chain can be used on a 9-speed cassette since it is thinner, but there are some caveats you should know. Therefore, the chain will move up and down the cogs without skipping or rubbing.

Actually, a 10-speed chain is thinner and lighter than a 9-speed.

If you have an older 9-speed bicycle that needs a chain replacement or decides to change your gear ratio because for one reason or another, then the question becomes, “will a 10-speed chain work on a 9-speed cassette?”Ī 10-speed chain will work on most 9-speed cassettes without an issue.
