It is a versatile frame. Mounted in Di2 Ultagra, TPU and GP5000 tire in 30 ( wheels 1330 gr ) , it weighs about 7.4 kg (size 54). The notions of rigidity, comfort etc. are very personal and therefore very subjective. Riding at 35 km / h is a warm-up for some and the apotheosis for others. I have not noticed any problem with the integrated handlebar but be careful with the measurement (100 mm = 110 mm). For the spacers, I do not remember if they are the original ones but I put spacers that clip on. This allows me from time to time to more easily clean the dirt placed on the upper and lower headset of the fork.
