Hi Golfer007 -
If you're shopping at Niagara anyway, you might do just as well to pick up a pair of their
cheapie Pyramid aero levers.
I don't know what you mean by a "48" chain - But if you're refurb'ing your Trek 560, there is nothing wrong with
these KMC chains. I've used scores of them on flips and my own bikes without any issue.
