I noticed recently, in investigating the q-factor of my bike, that my pedals
were unevenly spaced, i.e. the left pedal was 2-3 mm further from center
than the right. While 2-3mm isn't the end of the world, I'd prefer that they
be symmetric, or at least know why the assymetry exists. I figure this must
be one of two things - either the BB installation, or the position of the
cranks on the tapers - probably the former.
So I uninstalled my UN-72 BB and noticed that unlike Park's instructions,
where they assume that your BB will have a fixed flange and a removeable
ring - my BB has a fixed ring and removeable flange.
So a few questions. How do I properly install this BB? Also, is there
allowable left/right adjustment in the installation, or is there only one
proper installation position (which I assume should be centered within teh
frame)?
Thanks,
Kyle
