Hi Everyone,

I have Giant defy advanced road bike. I have question about my saddle height position, I hope some one can help me here.
I am male with 5'5'' (165) and my inseam is about 28''. Base on this website (Road Bike Saddle Height Calculator), my saddle height should be 30.5''. I just wondering is this number seems good to you?
My current saddle height is 31.5'', I don't have any shoulder, back and knee problem but my left leg hamstring get really tight after 20 miles. Please give me some suggestions.
