Interesting thread. I had to go to Vintage Trek to verify that this bike doesn't have aero brakes and you are correct. I did that because I have a 83, and it was the first Trek road bike to have aero brakes. Go figure they would go the other way later! If you are concerned about originality, save the parts you remove in a box. That way you can console yourself that you can always return it to "stock". I'm going to do this with my 560. But I would set it up the way I'm going to ride it. Look at it this way, yours is a more expensive "custom build", that ought to keep the nay-sayers quiet. BTW I really like that old Trek.
