yeah um. I wouldn't grease spindles. I made the same suggestion in another thread pertaining to this same topic and got educated. Coincidentally, or not, two days later my (greased) drive side crank nearly fell off as I was riding. I got a lot of creaking as a warning, but it was over a course of an hour of riding, which was creepy. The proper solution to this is to get the sugino BB and spindle, which will exactly match -as opposed to clone- the taper on sugino cranks. I'm riding some cheap sealed bearing BB with sugino 75's which is supposed to clone shimano which in turn should clone sugino. Too many degrees of separation. I got the spindle from QBP, now I've just got to save for some cups.
Also, I ride a Soma Rush.
