    Extender Cogs for 9-speed cassettes

    Anyone tried extender cogs with 9-speed cassettes?

    Looking to try the E*Thirteen 42T with my XT 11-34 (9-speed) cassette.

    I bought a 39T Action Tec & made a 39-11 9 sp. Works good. Would work even better with a radR cage on my Zee dérailleur....
    SPD pedals are an absolute menace to the well-being of the world, and ought be banned immediately.

    Correct me if I'm wrong but $107 for one cog seems too steep. For about $160 to $250, you can get a whole 10 speed drivetrain with an extended 42t cog.

    It was second hand NOS. I would never pay that for one cog.

    I forgot the page, but you can probably find it in google... some guy did convert a few of them. I think you need a shimano XT cassette in 11-34, and maybe another one to steal a gear off of, plus the extended range gear.

    From what I read, sram wont work due to the recessed gear on the cassette meshing into eachother. Lots of people saying it wont work. It seems to me that you could just grind down the lip on one gear, and ditch the recessed groove gear and it works. It *seems* to me that using a sram cassette and grinding down the lip would actually be easier than using a shimano cassette.

    I love 9 speed. Id actually rather use 8 speed, but quality parts are totally gone now. Nice to see someone keeping 9 alive!

    This might be worth a try. I may pick one up for my 9-speed fat bike

    Yeah, but then you'd have all new stuff and it would all work together. Who wants that?

    Yeah, 2/8 with a nice big cog would be nice...
