Position on my bike; opinions?

Hey,

I am new here so: Hello 

2 months ago I bought road bike, unfortunately frame is too big. I am around 5’8 ( 174cm) with 82cm inseam + 2cm in road shoes with cleats. Bike I bought it is Kross Vento 2.0 L, it means 574mm Top Tube ( Yes, I know…), 391mm Reach and 195mm Headtube. I did not have any experience and in shop bike felt quite nice, so I decide to buy it, especially that price was good. I do not want to buy new bike/ frame, maybe at end of next season to be 100% sure that I know what I need.

Setup on photo:

– Seatpost without offset; -20mm
– Stem; PRO LT 80mm -17 Degree, without spacers
– Handlebar; PRO LT 70mm Reach and 123mm drop

I tried also 60mm -6 degree stem, it was quite OK but I felt that little “too short”. 80mm -6 degree was also nice, but I decided to went little lower, so I bought -17 degree version.

It is hard for me understand one thing: in theory bike is too big, in practice I think it is not so bad. What do you think about my position? 

As I wrote above, I do not have any experience in Road Bikes ( 4 years on MTB) so it is hard for me to judge my position.

PS: If I made mistakes, sorry, I am still learning
