Hey, I know I should probably go get a fitting done, but atm I can not afford one. When I am riding it constantly feels like I'm falling forward. I notice that after some time my hands are starting to go numb due to leaning on them too much and not balancing over the center of my bike. My seat is level so I figured it's not that. I'm not sure if I need a taller stem or what may be the case, or if maybe my core just isn't strong enough. Im, 6'1, 265, havent been riding for quite a while and am now commuting to work 7 miles each way. I don't seem to have any other issues with a weak core though. Any advice would be great.
