"if you use quality parts and GOOD bearings and good rods and assemble it right it will be a good crank.. what else is there to wonder about? "
no reason to get defensive here. as i said before, joey and I were talking about these cranks few weeks back. it also came up from a buddy that there were some people who has these crank all out of wack, without much run time... yea great on paper Good bearings and Good rods will hold up fine, but the question is how do THESE rods and THESE bearings hold up...
