    SRAM PG830 vs PG850 interchange?

    Hi all,

    I'm looking to assemble a custom 8-speed cassette. Do you know if the sprocket and spacer widths are the same for the PG830 and the PG850 cassettes? Has anyone ever mixed cogs from these two cassettes?

    If there are differences they are probably minor. I think the difference between the cassettes is in materials but 8 speed cogs are all the same width as are the spacers (within a manufacturing group)

    Following up on my old post... Yes, they are the same thickness. The Performance house brand 8-speed cassette also has the same thickness cogs.

    I now have a custom frankencog that works great....
