I have already ridden this bike for more than 500 kilometers and I noticed that the stem uno is quite flexible. Otherwise, everything is fine. However, now it seems to me that even with my height 178 and inseam 84 cm I should have taken size 52, because the drop from saddle to handlebar looks quite small. Saddle height on the photo around 69-70 cm. And I feel numbness in the wrist while riding. I would be glad to hear an opinion about the size of the my bike.
Now the bike is on aluminum wheels ztto r1s (1600 grams) with Maxxis welter weight tubes and continental ultra sport 28 mm tires. I also used a full groupset Shimano 105 di2, everything works fine. rxl sl 38 cm handlebar and stem uno 110 mm. Weight with xpedo thrust 7 pedals 7.6-7.7 kg, if the scales are accurate. Thanks to everyone for the help.
