    Buying individual cogs for an Sram PG 990 9 Speed Cassette

    Is there anyway to just buy a few replacement cogs for my PG990 Cassette? I often double my mountain bike for fitness road riding duties so those bottom two gears get used alot and show signicant shark fin-looking wear while the rest of the gears look pretty darn good actually. It's actually causing a slight slipping sensation (i think) when im on my 11t gear when mashing hard.

    But for the life of me, I cant seem to find any vendor who sells just the 11 & 12t cogs (the ones not attached to the spider). Do I have to replace the whole damn thing just to get a new 11t cog?

    I've never found anyone selling individual cogs either. Would be a good service. I often have the problem of low availability of 34T cog systems in my region, so I simply re-use a 34T cog on a cassette for 32T, it works, although I would love to be able to buy the cogs I wanted, when I wanted them, rather than whole cassettes, as I often take my cassette apart to clean it and have a look at the wear then, and would love to be able run the widest allowable range on my 1x9 or future 1x10. Is 36-10 possible?

    In case anyone is wondering you need a Torx T7 to dismantle the cassette.

    XT M760 11t and 12t would probably work just fine

    Dragging this up out of the dead... with the Shimano 11t on a SRAM cassette, does one need to use the Shimano lock ring, too?
