I am 180 cm tall and I recently bought a Talon 3, with large frame and tire 29 through the website. I searched and I found that large frame is good for me. When I wanted to pick it up, I found it seems large for me and when I seat, my toes just touch the ground. Can I know if it is ok and I should replace it with another bike? I am new and I am not familiar how large my bike should be and what tire size is perfect.
