cmcanulty, when you say "I weigh in clothes about 120", you mean pounds, right? If so, that is about my weight and I agree with you "that probably gives me more of a margin". I would dare to say "that probably gives us more of an advantage" for weight loading on the bicycle. How much weight do you estimate that you carry on either of the racks? For how long do you tour with those racks? Did you have any trouble with the racks? According to the pictures they seem to be a bit fragile and I hope I am wrong.
