Thanks for the additional comments. I will try to get some pictures up so that you guys may see something that needs to be fixed. I have been working on the cv axles of my truck for the last couple of days and it has been raining in the evening so I have not been riding or doing much further testing on the bike. I will get my wife to help me post up some pictures maybe later today or tomorrow.

This problem is not something that I can't live with but it is a problem that I would like to have some answers as to what is causing this down shifting.

I would also like to apologize for coming across as being a know it all or smart A. I did think that some were pulling my chain and I was waiting for someone to ask me what color shirt that I was wearing. I should not have been thinking this way.

The little pin on the large ring is lined up with the crank arm. I am thinking that this is to keep the chain from dropping between the large ring and the crank arm as well as an indicator showing how to orient the chain ring. The cage of the deraileur is about 1/8" above the top of the tallest teeth on the large chain ring.

I know that this must be puzzling to you guys because you can't look at the bike and I am looking at the bike and I can't tell what needs to be done.

Thanks again.
