Leg EndsAll tripods and monopods in Series 1 and above are provided with removable rubber feet. This feature allows you to easily change worn out rubber feet or to fit other accessories, such as spiked feet or snow/sand shoes. (4 sections tripods in Series 1 are excluded because the final leg section is too narrow to fit these ends). , ALR - We have introduced a new Anti Leg Rotation system, which means the tripod can be opened in less than 15 seconds. Simply loosen all the twist locks on each leg at the same time, then pull the leg down and tighten the locks individually. , G-Lock - G-Lock is the new Gitzo leg locking system. The locking mechanism has been completely redesigned in order to achieve a 20% increase in rigidity, faster operation and stronger, safer locking. G-Lock's special design also provides a “gravity lock” effect: the higher the load applied vertically to the leg, the stronger the lock.
