I hear ya. I was going to chop the extra length off and grind them after I had the rack alignment down (and drilled accordingly) but I really wanted to just be done...especially if this frameset implodes after the first ride. Figured if I make another set out of stainless I will adjust the length accordingly.
I don't mind the little extra overlap aesthetically as it hides the rack bosses. I stopped caring about weight several years ago as I've passed over or sold off "heavy" parts that I'd now love to have back.
