Thank you Frnchy,
I already have G056 frame for over 2 years - no complaints, but I would like to try something new. I tried a friend's grail slx in size M (I'm 180 5'11") and suprisingly it was good size for me, but what I noticed most was the exceptionally good power transfer - way better than my G056. The real grail has a major flaw to me - max tire size is 42 mm in the rear. That's why I think G068 is better construction as I ride mostly on 45c tires
