Can you sit on your saddle and just barely touch your toes, not touch your toes nearly at all or can you put your feet down? Is your saddle all the way forward, in the middle of the rails or set forward or behind center?

Of course, I could be wrong, but I think it's something to look in to.
I think the height of my saddle is fine; slight bend in the knees and can barely touch toes when sitting. It looks like it is about 2/3 of the way forward.

My boyfriend, who used to work in a bike shop, "fitted" it for me. I'll ask him about the saddle possibly being too far forward.

Thanks for all the suggestions!
