There is still nothing quite like the Alien from Fixe Hardware, and the Alien Hybrid Revolution is an improvement on an already great design. They are 20% lighter than standard Aliens, with improved components and a narrower head width. These little offset babies are great for aid and free climbing alike; and are perfect for pin scars and weird pods. These Fixe cams feature stems that are very flexible in all axes, narrow head widths, and soft alloy cams with a large camming angle and a very innovative trigger design that works beautifully and is very durable.TECHNICAL SPECIFICATIONS & FEATURESBrand:- Fixe HardwareAxle Design:- Single AxleStem Type:- Flexible Single StemNumber of Cam Lobes:- 4 CamOther Features a 20% weight reductiona Reduced head width for shallow placementsa Ergonomic rubber thumb pulla Stronger aluminum cable swagea Aluminum trigger componentsa Replaceable steel trigger wiresa Riveted axle
