I have a Brooks B17 on my touring setup and a Swift on my Specialized Roubaix. I don't seem to have a problem with the B17, but I'm not sure if I have one with the Swift. I'm getting a numb penis. I think from the Swift. I keep changing out riding between the two bikes. I was wondering if you have heard of anybody that has that problem with the swift. I have about 500 miles on it now and it's pretty comfortable so I hate to get rid of it. I've tried the Specialized Toupe the Fizik Arione, the Terry Liberator and a lot of others in between and this one is the best so far. The Arione was pretty comfortable for a few hours, but that was it. As you can see, I've spent a lot of money on saddles and I'm about ready to give up. I had another one that keeps getting my attention and that one is the San Marco SLR. Anyway any ideas would be appreciated and thanks for taking the time reading this.
