Grog - thanks for the explanation about shoulder pain. Now I'm VERY surprised that I didn't have any when I got back on my bike after a 15 year break - no one could by any stretch say that I have a strong core!

SadieKate - I guess I should consider upgrading my brakes (along with the shifters, crankset, freewheel....)!

AuntPetunia - my mind must have done a little mental hiccup when reading your post - you were clear on the brake issue and I totally answered something else. Sorry!
