Put on new United nash cranks tonight. That was a painful install, the finish look is awesome, pretty excited to see how the 170's will feel as its moving both feet 10mm closer together. The splines need to be tapered more, i almost had a hernia putting those on. Grease does nothing, the clearances are so tight that it just pushes the grease right off the spindle into the spacers. I think im going to have a hard time taking these off down the road.
