Mechbgon, Thanks so much. I didn't understand that the cup was a separate part of the cartridge bottom bracket. All the pictures I've seen on Nashbar, Harris and even the Quality Catalog on Harris, showed the cartridge bottom bracket as one piece. The cambriabike.com website shows the cartridge separate from the cup. I wasn't sure if I had to order new cranks to get the new part or a new cartridge bottom bracket.

I don't have a grinder and that is really too much for me, so I will be sending the chainrings back. Since the middle chain ring was really worn down on the ebay Trek 520 bike when I took the rings off and took all the thick oil off the teeth, I had to order a granny and a middle ring rather than just changing out the 30 tooth granny for a 24 tooth granny. I decided to order a new large ring and lower the front derailer for a touring setup. Now that I have to order a bottom bracket, I may order a cheap crank for around $69 for an ATB Treking Crank on Nashbar and change out the granny 26 to my new 24 tooth, Then I'll get to learn about chainline issues. I'll be changing the spindle size from a 118 to I think a 121. What a great winter project!
