Cyclattewrote a review of Oakley M Frame Sweep Replacement Lenses on October 16, 2007
I finally got my act together and purchased clear lenses for my M-frames. I have not been disappointed. Pop them in for early morning rides when it still dark and my eyes are still protected. Great for cloudy days when there is no glare to contend with either! A must have addition for your M-Frames.
