It's a case of religion vs science. Some folks on the forum just simply believe in Shimano without question. Others add in craft, experience, engineering or common sense and continue to wonder.

This string has had a respectable amount of participation. The sum total of my understanding about this issue has come from this string; both from those who agree or disagree with me.

One would think that Shimano, with their marketing prowess would address this. Since marketing, in part, seeks to mold perception of their product; is a savings of pennies on a part, followed by a non-responsive stance, worth the potential loss of customer confidence? I wish that Shimano would weigh in on this. I think that their customers deserve answers and would welcome any information.

Meanwhile, the failure of, or uncertainty about, Shimano 26,54 and 55 BB's has led me to buy Tange LN-3922 BB's. I have not had problems with 3 of them so far.

After all, I'm just wrenching and riding. Don't care that much about marketing.

Happy Thanksgiving to you all.
