I've a friend that has expressed an interest in cycling recently. His concern is that he'll not be very comfortable with the seats he has seen in the LBS. He's pushing 300 lbs I'd guess. Any suggestions for a saddle? I remember seeing one before at a bike expo a few years ago that looked similar to a small bench, has anyone tried it? Thoughts? Or will the standard saddles work as well after a break in period? Thanks.
