    Can F4R rods be used in and F7R ??

    F4R Crank bore size is 1mm different vs F7R

    Do you just use F4R Bearings? are they >5mm thicker (1mm total either side)

    Anyone using them ?

    They're the same dimensions, the only fitment difference is F4R rods dont have a slot for an alignment tab
