Incredible expansion range and low weight make the Black Diamond Camalot C4 Package a perfect way to start off any trad rack or beef up an old one. These five cams (size 0. 5-3) cover all the bases from fingers to fists. The new Camalots are so dialed that two half-sizes were eliminated because the new increased expansion range deemed them obsolete. In addition to providing this increased range, the double-axle design makes these cams full strength even when placed passively. With all these advances, Black Diamond still managed to decrease weight by 30%, because no one likes weight.
