34 yo trying to get into shape. bought too much bike, but really like it. Cannondale 5C. Am really enjoying riding. Have had it 2 days now and am concerned my frame is too small. So hoping forums will help.
Take it back to the place you bought it and swap for one the right size. If you bought it used, continue enjoying it while you look for your second bike. Maybe a stem of different angle/length will make it better for little cost.
