Brooks B17s are very good. The company has been around for 100+ years, and thousands of cyclists use them.

Including me. I've got a B17 on each of my bicycles. I wouldn't use anything else.

One nice thing about the Brooks saddles is that they conform to your butt ... they customise themselves to your butt.

However, be aware that the Brooks saddles are very, very hard, and do require a bit of work and lots of patience.
