    What to do with a basically new specialized stumpjumper m2

    OK I have been looking into building this basically NOS specialized Stumpjumper m2 into SS or possibly geared bike and it depends on how much I decide I can spend on it. If I go SS then I need a little help sourcing and EBB for the 73mm hub shell and I would like to go with Trickstuff Exzentriker but I'm not sure if it's available in the U.S. and can I get it through an LBS or is it available online with U.S. shipping.

    Thanks

    Personally I would opt for a White Industries eccentric hub rather than going with something like the Exzentriker. Here's a link to their website: https://www.whiteind.com/rearhubs/singlespeedhubs.html

    SS that badboy! What you need is a Forward Components EBB. Link. High quality stuff, but it might take about 6 weeks to get one. It'll work with the 73mm shell, just don't use the included spacers.

    Thanks for the replies, If didn't already have an almost new transition revolution 24 26" wheel set, 17 tooth Kick As.. Bikes cog then I might consider the ENO hub. Correct me if I'm wrong but according to forward components website, their EBB only work with a 68mm BB shell and the Trickstuff Exzentriker is said to work with a 68mm or 73mm BB shell and I have a 73mm shells which means I can't run the Forward components EBB Correct.

    Well I just re-read the FC EBB instructions and indeed it's not for 73mm shells. Bummer.

    Hang on, man. Check out post #35 in this thread. Looks like there's a workaround for your 73mm shell!

    You could also use a Philcentric BB.

    Thanks for the replies, it looks like I will be off to the LBS soon and see if we can get this sorted out either by facing the bb to 68mm or getting the Philcentric EBB which looks like a very good option.

    I'm all about SS, but I'd like to see this built up with 3x8 and XT/XTR V-Brakes. Maybe those green Mich tires.

    I had a blue Stumpjumper M2 and S-Works M2 and loved them both.

    Magic gear ratio? There is probably one that will mean you don't need a tensioner / work around and get good chain tension. I know it is 36:18 on old Bontrager frames but there is an online calculator (fixmeup or something) that will calculate it for your particular chain length! SSP

    You might have seen this already but just to give you encouragement and it's the same color. You will like your new SS.

    If you don't want to deal with the e-bb why not just use a Singulator tensioner first to see how you like the ss? Yes it is a little less minimal looking than a straight chain but it will work fine and it's a lot easier and cheaper. Especially if you already have a standard bb laying around.

    No it never stops hurting, but if you keep at it you can go faster.

    I have a ss stumpy m2 with a rigid fork.
    I suggest using a tensioner first. if you like the ss thing and want to try ebb then your not out alot dollars. I've never had problem using tensioner's on both my ss.
    Your frame is in really great conditon so I would really consider what another poster suggested and finish it with a xtr drivetrain. Good luck!!

    Honestly if the frame were mine I would make it a project/bargain build. I'd go for a 1x8 or 1x9 using old parts that you have, your friends have, or what you can find online. That's just me though, I've always wanted to do that and the frame seems like a perfect candidate. You'll have an versital custom ride without spending a lot of money. But if you want to try single speed (or add another SS to your collection) then totally ignore this post haha

    All good points about trying out SS before I go to far with it. I will check when I get home but I'm fairly sure that I do not have a 73mm square taper in my old trek 850 so I may end up just going all out with all new parts for this build as is pretty much all my current parts are toast, and I probably won't, (but keeping an eye on flea-bay) be able to find a good donor Sid SL fork so I am thinking about rigid fork as will.
