Cycling sure does not cause prostate cancer. And also, prostate cancer is almost never painful, at least till it spreads, then its a different thing. So get your annual PSA.
Glad you found a saddle that is comfortable Stepfam. It must put your weight out further laterally on to the bones.
I Bike - is the Rans CF saddle as comfortable as the average bent saddle with no back to it? And is most of your upper body weight still on your spine? After a bunch of back surgeries I find the big seller of a bent seat for me is that a lot of the upper body weight is taken up by the seat back. I'll have to ride a Rans CF someday but no dealers around here.
