I guess i felt a little stretched out when reaching to handlebars. I felt more comfortable on handlebar tops , holding from hoods puts a little bit more strech and drops were killing me. When i'm on the bike holding from brake hoods if i am not leaning towards the handlebar my arms are straight but i don't usually lean on because that i am using glasses i need to look up higher and that puts more strain on my neck.

I had neck problems before this bike , i had a mtb but that was short for my height. Unfortunately i have the similar problem on this one too.

I guess getting a shorter stem and neck exercises may help. There is only 2 places that do bike fit in Turkey. I had a bike fit for my previous mtb bike it was a BG Fit that is specialized fitting method. But because my bike frame was really short for me that fit was not successful. I can't afford a bike fit right now.

If i had a roller i would post a video that can show you how my body positions on bike but i don't have one right now. Thank you for all your replies.
