I am building up my first bike and was wondering about two things... what is teflon tape? I am installing my bottom brackett, ultegra 6500 and it seems pretty simple, do i need to do anthing other than screw it in and tighten it down? and question 2.. do I need to apply any grease or anything to the casseste when I install it? or do i just slide it on and tighten it down, thanks for your help... I am new

Teflon tape is placed on the threads to allow the threads to slide more smoothly as you are installing them. Basically, teflon tape provides a low-friction surface and easy release (like when you are trying to remove something). Personally, I have never used teflon tape and have never had a problem with the BB area. I do apply grease (Phil Wood) to the threads though. Now, branford bike ( ) indicates the following: "Adjustable cup is lightly coated with thread lock and should be installled in a dry, clean bottom bracket shell. Do NOT grease or lubricate the threads. It is ok to grease the drive side steel cup threads." I would suggest using a torque wrench and install the BB to the recommended torque value. You can pick up a decent torque wrench at Home Depot or Sears, but many other places carry them as well. Also, you may want to check and find helpful info in their workshop area.

I haven't ever used it--grease works fine, and I always have it around--but Teflon tape is a standard item in plumbing. Any hardware/home improvement store will have it.
