ya know, I dont understand this whole slippage issue. I dont slide around much on my bike in any kind of riding unless its intentional (or on steep inclines and declines like trips home area), but I use my legs to grip and shift. Maybe my experience riding horses helps with this, but I just dont understand how people move around so much and worry about sliding...
That said, I like the clear ones! And the smaller ones like Dim's are super classy lookin!
