8 speed spacers
 

i have set of 13 or so loose, flat titanium cogs that i am going to use in an 8 speed cassette set up that is on a cassette body that will accomodate up to a 10 speed cassette. what size spacers do i need to ride between the cogs to make them work?
thanks for any help.

You need to measure the cog thickness too as the spacing will be dependent on both the cog thickness and the spacer thickness.
