I bought a bike online based on a recommendation that a 56cm frame would be ok for me (I am 5ft 10, with 30" inside leg). However I think it is slightly too big. I have to lean forward a lot and my arms are almost locked out to reach the brakes. At the moment, the handlebars are on the lowest setting. It makes it very hard to look over my shoulder to turn right and if I do I sometimes lose balance and swing into the middle of the road...lucky there was no cars there at the time.
Is there a way for me to move the handlebars closer to me?
