:-DCool but you will have to put some real good gussets in,I dont want to tell you how to suck eggs but just from the photos I can spot two fracture points the first is at the front down tubes as they meet the bottom rails and at the rear where the rear wheel brace tubes meet the cradle, should be fine with good gussets dont skimp though and tell me where to go if you feel so inclined, I just dont like people hurtin themselves.Nice riding position though good luck with the build, when are you looking to race?
Cheers Oz
