At 6.78 kg, it's not super light, but in my view this is the best looking frame on the market (and it looks like it will stay like that after the release of c68...). It also has 56mm aero wheels and 28mm tyres, so I'm fine with the final weight.

I've made a video for my Twisted Wheels Youtube channel with the weight of all components, I hope you'll like it
can't wait to see what you would do this this c64 in the future. And yes I agree c64 looks nicer than c68, in fact I prefer the c60 rim brake with its lugs and 3k carbon parts. Fun fact: your C64 is the last pride of Ernesto Colnago where still got his signature
