I have only ridden my new Cervelo once, I put 42 miles on it everything felt fine. Today while cleaning it I noticed that the bottom bracket is tight. It turns smooth, but feels like a lot of drag on it. I have checked and nothing is visably dragging. I can see grease so I know the bearings are not dry. This is the first bike I have had that with external BB bearings. It this normal? Will they break in or is something out of adjustment?
