Note that the cup with the ring machined into its exterior shell is the right-side (drive-side) cup.  This bearing-cup assembly will thread counter-clockwise into your frame.  The other cup is for the left-side (non-drive side) of your frame.  This second side cup threads clockwise into your frame.  This is extremely important to understand before you try to install your bottom bracket!

Here are a few informative pages/videos that will help you install your Euro bottom bracket cups and the correct size tube spacer:

Also note that the tube spacer goes in between the bearings, like a sleeve over the axle, which prevents the bearings from being smashed into the frame when you tighten the crank arms.  If the tube spacer is too short, even by just a few millimeters, then it's not doing its job. People will say, "I tightened my cranks down and now they won't spin freely."  That means the tube spacer is too short.  If the tube spacer is too long, the bearings will not seat all the way into the frame.  Normally a 48mm tube spacer is used with 68mm BB shell and a 53mm tube spacer is used with a 73mm shell.
