New Metolius Offset TCU’s are designed specifically for hard to protect flared micro-fissures & pin scars. They use two smaller cam lobes and one larger lobe to accomplish this. Working with Ivo Ninov and partners over the past two years has convinced us of their validity. Ivo has raved about their performance on free & aid walls in Yosemite and Zion and is quoted as saying "you guys must do these units…they are sooooo bomber"! The narrow head width fits nearly anywhere and the U-shaped body absolutely doesn’t hinder placement. In fact it gives a very stable framework in which to hold the cam lobes. Unlike other brands, the Metolius TCU’s can withstand multiple walls worth of abuse. Offset Cams are specialized pieces designed to fit in flaring pin scars, primarily for aid climbing. Cams placed in flaring cracks are far more susceptible to pulling out than placements in parallel-sided cracks. Climbers using Offset Cams should be very experienced in the art of cam placement and thoroughly understand the limitations of cams placed in flaring cracks. Features: Opposing tube and Dyneema sling colors enable easy identification as an Offset TCU. The color of the sewn sling denotes the size of the two smaller cam lobes; the tubing color represents the large cam lobe size. Direct Axle Technology makes Metolius cams the lightest in the world; opens more placement options in bottoming cracks and shallow pin-scars while providing the best visibility of cam lobes in tricky placements. 13.25 degree cam angle for more outward force means Greater Holding Power! U-shaped body for greater durability & unparalleled control during placement and retraction. CNC machined cam lobes from 7075 T-6 aluminum, for the tightest tolerances and greatest strength to weight ratio.
