    Want to put a Shimano Octalink V1 BB on my bike

    I checked out bikepedia and it says that my bike, Scott Speedster S60 has the follow BB setup:

    Bottom Bracket TruVativ, 113mm spindle
    BB Shell Width 68mm

    I got somepower cranks I would like to test out and they use Shimano Octalink V1, so I was wondering can somebody advise me what I need to buy to install into the BB shell so I can attach these cranks.

    Many Thanks,

    You need the Park BBT-22 tool to remove the bottom bracket you have now and install the Octalink V1 bottom bracket. There are some instructions on the Park Tool site if you need them.

    The BB width indicates that yours is "English" threaded, meaning that the drive side cup is reverse threaded.

    Clean out the BB area and threads, and use some grease on them when installing the new BB.
    There's sometimes a buggy.

    One.

    So let's just say I'm drivin' this buggy...
    and if you fix your attitude you can ride along with me.

    Hi guys,

    Thanks for the advice, so I simply need to buy a English Threaded Octalink BB and it should install onto this bike ok.

    I am looking at buying some on the web.

    I see them in sizes 70 and 68, I need 68 obviously.

    But I can see different spindle lengths.
    chainreactioncycles.com/Models.aspx?ModelID=906
    68x109 and 68x118.

    Which do I need? Why does it matter?

    It depends on the crank. The manufacturer of the crank you're going to install should specify which spindle length goes with that crank model. It matters because you want as straight a chainline as possible. Only the crank designer/manufacturer knows which spindle length will give you that with his crank.

    Other than that, yes, all you need is the proper English-threaded Octalink BB, the Park tool, a big wrench and some grease. Lately, Shimano has advised against greasing the removable cup if it's plastic. I ignore that, but perhaps there's something to it. Small tip: to hold the Park tool in place when you reef on it, I've used a large woodworker's clamp around the bottom of the bottom bracket for a field expedient. Good tip if you already have one of those around the house or shop. Ignore it if you don't.

    109 is for double chainring setup, 118 is for triple chainring setup.
