ok, so I searched and found some others with this problem, but did not really understand the solutions offered.

here is the problem, i am installing a race face, cartridge bb. as i tighten it down, the spindle binds up and becomes hard to spin. i installed it by threading in the non drive cup 3-4 turns, then tightening the drive side snug, and then tightening the non-drive snug. then, the spindle becomes too tight with the non-drive cup not completely threaded in, it spins freely.

could someone please offer me some advice. much appreciated!

could someone please offer me some advice. much appreciated!The non drive side only needs to be snug,and if that causes binding,you likely need the shell faced. However, the drive side needs to be more than snug.There is a recommended torque spec.

Don't under estimate the importance of using the right torque on the bottom bracket. Find the specs and use a torque wrench or you will have more problems.
