Cassette number of teeths ?

NoradMTB · Mar 12, 2016

Hi,

Just interested to know what is the main difference/purpose between different teeths configuration on a cassette. Is there any compatibility concerns about that ? For example, switching from a 11-32 to 11-34 or 11-36.

Thanks!

Sometimes with a larger range you may need a longer cage derailleur, but probably not. Going from 11-32 to 11-34 or 36 is not that big an increase. You're chain may a bit short though.

The more teeth on the cogs - the eaiser it is to peddle uphill. I'm using a 11/40 tooth cassette on my bike because I do a lot of climbing. Going from a 11/32 cassette to a 11/40 cassette might require a longer chain and derailleur.

More teeths, more chains.

Less teeths... hows the rest of that go?

Simple elementary mechanics. Think long vs short lever.

Alright thanks and how do you determine how many teeth a cassette have ? It is just the count of teeths the biggest cog have ?

Each cog in the cassette has a certain number of teeth. The smallest cog may have 11 and the largerst may have 36 - hench calling that cassette a 11/36.

A lot of cassette have the number of teeth on each cog - sometimes they may be hard to see.

The numbers used when describing cassettes are the number of teeth on the smallest and largest cogs. The smaller the cogs the harder the gear will get and the faster you can go. The larger the cog the easier the gear you will have.

The limit of the cassette range is the capacity of your rear derailer. Most 8 and 9 speed mtb rear derailers are limited to 34 tooth clogs, most 10 speed derailer will go to 36t, and most 11 speed derailers will go to 42t. This is speaking generally and can change based on model and brand so it is a good idea to do research before buying parts.
