• Sounds ok to me for the crank arm yeah.

    However, in order to run the 44t chainring they say you need 85mm width limit, 92mm from the BB line. Bear in mind you would be bringing all these measurements 5mm closer on each side so you'll need nearer to 75mm to have it covered by their standards.

    Then that just leaves the pesky lockring (which was the issue I was originally most concerned about - and is the problem they refer to in the other forum links).

    And just to add to the evidence that this is not an exact science - here's a guy who claims to be using a 107 bb for a 43mm chainline. Possibly moved off centre with a Phil BB??
