This item delays your bike getting sweat on by 15 min. It consists of a thin towel which absorbs sweat and then funnels it directly into your bike parts where it causes damage. Obviously, a major design flaw, and no good for any athlete doing a serious indoor workout.
I did not realize how much you sweat on a trainer when there is no wind. I drip sweat off my chin and nose, which would usually land on my frame. Sweat can be corrosive to some items, so the Cycleops bike thong is great at not being in the way catching all those sweat drips.
Have been working out on my trainer with a new computer training program. Slob that I am..the sweat has really annoyed my Madone. Not only is the thought of a Thong exciting..but the Madone is beautiful wearing it. No more sweat.
