I am back into cycling after many years off.

About me..I am male 44, 5' 8", 250lbs (working on it , riding a 54 Orbea Aluminium with Carbon forks and rear...

My concern is 30 minutes into my rides I start getting the dreaded numb hands/fingers.

I was wondering if my handlbars are too far away and or low?

Thank you for any suggestions.
