    2008 Hi Fi BB/crank question

    Have the base model 08 Hi Fi that came with a Shimano FC-M442 crank set/BB (I think square taper?). 68mm shell width on the Hi Fi.

    Any problems or issues upgrading to a SLX FC-M665 Hollowtech ||? This is a 2 ring specific (22/36) crank set and BB that comes with a bash. I would also use the Shimano FD speced for this crank set.

    M442 has internal shell bearings for the crank vs. external for the M665 but this should still work fine I presume?

    I had a 2009 HiFi that was also the base model that came with the M442 crank as well. It is actually an Octalink style BB. I put on a 2-ring XT crank with a Hollowtech BB on it last year with no problems.
