    How can this be? splined/square tapered

    My crankset is the Shimano FC-M440 (engraved right on the crank arm) and everything I have found tells me that this is a square tapered crankset.
    But when I take the crank bolt out it looks nothing like a Sq-Tapered deal, in fact it looks almost exactly like this splined Octalink pic I found at the Park Tool site:
    http://www.parktool.com/images_inc/r...help/bb228.jpg

    So is it possible that the engraving is wrong or am I missing something?

    When you removed the crank fixing bolt, how big were the threads on it? If they were 8 mm it's a square taper. If they are 15 mm, it's an Octalink.

    14.91mm by my old calipers. I was already thinking it was octalink because of the 8 splines I see when I take off the crank bolt and look in there.
    I wonder how this can be though, I can find nothing online about the FC-M440 crankset being octalink, everything I see claims that crankset to be square tapered, and I know I'm not reading the numbers incorrectly.

    Based on these two documents, the FC M440 came in both square taper and Octalink bottom bracket types despite having the same model number. Surprising.

    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.
