With longer rides appearing in the schedule more frequently, friction is a major concern while being in tights for so long. I have become a huge fan of assos chamois cream. It keeps everything moving and cool in the tights, helps with saddles sore and elongates the life of your favorite chamois.
I might be trying a new cream this year. Enjoy David Zabriskie's new video for his new chamois cream, D-Z Nuts.
