I rode my Trek 7.2 fx the other day for about a half hour after not riding for most of the winter since recently getting the bike new in october and not riding a bike since I was in high school. After about a half hour of riding I had some tingly numbness and purple colors in my genitle areas. The nearest thing I can figure is I got a bad seat problem. So in your guys opinions what would be a recommended seat to help correct this issue? Because as of now im a bit hesitant to ride the bike again. Thanks.
