I have a Trek 1.2 and I find the saddle hard to ride on after a while. I get a sore bum after just 1 hour (8 mile ride). I wear bike shorts, etc. I don't know if I must get used to saddle. I have had bike 4 months. I can't ride everyday because of this. It seems area around site bones ache.

How do I go about getting good saddle for me?
