Trango Flex Cams offer up a killer combination of function, quality and value. They've added a #0.5 and #9 to extend the range so they've got you covered from sub-tips to big fists. The axle lengths have been carefully calibrated to maximize stability and minimize walking. All sizes still have the doubled UltraTape slings so you can clip in at three different lengths. All this and they're still one of the lightest and best value cams on the planet.
