685Mm stock 620. I am 6'1 225 bench 360 so i have wide shoulders did 40 miles today . The bike rides really well but not like a big tire shock bike.I have added 700x32 tires with 80lbs of pressure carbon post and handle bars. I had a giant comax 2 before these and this bike blows it out of the water in confort.I have been fighting a creaking noise that is driving me nuts. Need to figure out if its the lower bracket may have to remove and grease.
