replacing power spline - go for isis or hollowtech

Hi,

The bottom bracket on my I-drive 5 was playing up a bit, so I ordered an FSA Platinum isis BB thinking it was the same as power spline, but of course it isnt. As far as I can see there is only one power spline bottom bracket, and it is a pretty budget affair so I dont want to go back to that.

So now I have nice shiney new BB that my cranks wont fit.

Just looking for a bit of advice here. I have read bits and bobs in the forum that suggests ISIS has inherent problems, and that hollowtech is the way to go?

So I have what I think is an OK isis BB, and was looking at :
http://www.chainreactioncycles.com/Models.aspx?ModelID=3932 for cranks, coming in at about £65 total.

Would you folks suggest sending the ISIS BB back and getting some model of hollowtech, possibly the saint setup http://www.chainreactioncycles.com/Models.aspx?ModelID=3404 as it seems like they are the dogs b*.

Is facing a frame to get a good hollowtech setup something that could be done at home with the correct tools, and if so what would those tools be?

any advice appreciated.

cheers.

    the correct tools are abour 600 pounds. LBS job.

    just get cranks to work with your new bb.

    If you want a bomb proof bottom bracket without the need to face your frame you could get the following:

    XT Octalink BB http://www.chainreactioncycles.com/Mode ... delID=1002

    And

    XT Octalink Crank http://www.chainreactioncycles.com/Mode ... delID=2737

    They will outlast Hollowtech II.

    blimey, £600! what is facing exactly, is it re-cutting of the threads in the frame to make them stronger?

    Splasher, that XT crankset says "For use with Super Narrow HG chain" . I'm not entirely sure what one of those is, so would I have to change that too?

    cheers

    have a read of park tools. it uses parts of the bb thread tool and a face cutter.

    You should be changing your chain anyway with new chainrings. Chain width notmally depends on how meany gears you have.

    It just means a standard 9 speed chain, Shimano or SRAM.

    thanks for the info folks. I had another thought anyway, i wondered if the i-drive bottom bracket hanger would even need facing.

    probably gonna go for the xt kit recommended anyway.

    cheers
