Ball bearing tightness?
Hi I'm sort of a newbie here but I was wondering what you ppl consider the optimal torque or pressure on the ball bearings that connects the wheel to the axle.
I have a bit of experience with this. I have a nice cheap department store mountain bike, a Mt Fury Roadmaster. I initially modified it to be loose enough so that I could spin the free axle (holding the wheel) for maybe a couple of seconds, thinking that it would minimize friction. But then that led to disaster, since the ball bearings wore down fast and soon I had a lockup. Apparently when I opened it up the bearings were almost completely abraded and destroyed. That was half a year ago. Now I'm doing just the opposite thing - the axle is now tight enough so that I have a dificult time turning the axle with my bare hand (again, holding the wheel stationary). My intention is to minimize the slip between the bb and the track. Is this the best thing to do? Or can I loosen it up a little without expense of bb life?
