Could someone please explain the difference in cassette sizes. I am busy building a new nomad carbon for am riding and confused on the cassette options.

Cheers

The numbers are the sizes of the smallest and largest cog on the cassette.

From the sizes you mentioned, the smallest cog on the cassette has 11 teeth. The biggest cog on the cassette has 32, 34, or 36 teeth. If they have the same number of cogs (likely 9 or 10), the cassette with the biggest cog will have the largest differences between gear ratios. One click of the shifter results in a more noticealbe change.

The more teeth on the cog, the easier it is to pedal. The 36 tooth cog will give you the lowest gear ratio, making climbing slightly easier in some cases. You can often save some weight by going to a smaller sized cassette.

Thanks for the explanation. So DH bikes would run 32, most other maybe 34 and guys who need to climb more 36?

A DH bike will have a 24-28 large cog.

What you "need" depends on your abilities, terrain and chainrings.

Any of the cassette sizes you mentioned are appropriate for a Nomad.
