Hello, I was just working on my bike before- it's a '76 schwinn continental with a 1 piece crank. I degreased all the bearings and cleaned out the crank area, but now I need to put it back together, and i'm not quite sure how to tell if the crank is tight enough, or too tight. Is there some easy way to tell?? Thanks a bunch!

It needs to be tight enough so that you can feel no rock when you push inwards on the tips of either crankarm. It needs to be loose enough that it spins freely. You'll have some difficulty finding that sweet spot and getting the bottom bracket to hold that adjustment as you tighten up the lockring. It usually takes me several tries to get it right.

Man, I thought I was the only one who needs 15 minutes to get bearings j-u-u-u-st right.

Not only that, but pedaling up and down wants to loosen the crank, so you have to check the locknut for tightness after riding a day or so. One piece cranks don't do that as much as square tapered press fit cranks.
thanks guys.. I guess i'll have to fiddle with it! :)bonsai171
