A torque wrench? Jeez... Yea i know what special tool youre talking about, but I only had to use that for the bolts that held the smaller chainrings to the larger one. These bolts (and the one original) holding the crank and ring together are regular hexagonal nuts.
And every time I tighten them down I do it to the point where I cant go tighter without stripping the heads. They just keep coming loose 30 minutes into riding.
