Slipstream Anti Chafe Sports Cream. Last year I had some bigs ride with long training rides and I found Assos and Chamois Butt’r weren’t helping. This cream (and TR) got me through the year: 25 hour Red Bull Timelaps on the trainer, 250 mile single day ride, week long 770 mile trip and multiple 100/150 mile training rides.
Little is more with this cream.
