you're the one that has to answer the question. Is it too heavy for you?
Or could it be part of your weight training program, to have a goal where you can finally lift that thing above your head?

My expensive custom road bike weighs at least that much with all the junk i put on it. How does it feel going down the road? does it fit you?

do you like it?

can you do what you need to do with it?
