Also, I might paypig a new frame. My Look was riddled with its bad ovalized BB, so I sold it away during the winter. I came across a very nice Trek Emonda SLR which is an even lighter rim brake frame. I have no rational reason for buying it but it looks great and I can build it to 6-6.5kg easily and then use it for nice summer rides. I'll either use my Campag SR groupset for it or then sell it and buy a used Dura Ace R9100 instead.
