Yup . Can I quickly ask why, in the above picture, does the stopper ring (or crank-stop) not extend into the flute of the spline at all? I thought the ISIS standard accommodated for this by ensuring that the ring goes about half way along the radiused end section of the flute. From the looks of the Moe BB it will royally rape your cranks the first time you put them on making them as saggy as a saggy thing. Figure 1
