That'll be the first thing to go. The seatpost collar looks kind of chunky and heavy too so that might be switched out too.
The collar was the second thing to go for me.
I want to say that my Small frame with bb bearings, collar, hanger, and cage bolts came in at ~1375. Dont remember fork weight but it wasnt bad. Ive got Sram Red, SISL cranks, alloy cockpit, and carbon post coming in at 7.1 kg's if I remember correctly. New wheels are going on soon which will change that number so I will check again when that takes place.
On the wheel subject, I blew through the stock wheels in a month and had them warrantied due to bad front and rear hubs. The hubs say DT Swiss but they are 100% Formula hubs.
My 52 is now for sale too, but not because I dont like it, but because having a Spec no longer meshes well with my new team.
