Although a bike may fit you appreciatively according to your inseam, but the top tube and stem length might cause you to be too leaning forward than what you would prefer. Best bet in this case would be to find a bike with a shorter top tube or get a shorter stem.

Also, at 34inches inseam, you'll want roughly 180mm crank arms.
