The RIBCAGE has been one of the only rims to have true design breakthroughs in the last few years. The spoke holes are drilled and re-enforced with ribs for cross-spoke lacing, where the spokes goes from one side of the hub to the opposite side of the rim for increased strength. The cross-spoke created more of a web of structure, which multiplies the stiffness and strength. This has been adopted by a few other companies, but never done as well. The outer walls are extra thick to protect against case dents, while the other walls are extra thin to keep it light. The entire design revolves around the use of 7075 aluminum material. At 500 grams, the strength to weight ratio of the RIBCAGE cannot be matched. The 36 mm width and 18 mm height are also major factors in the design, spreading out the impacts and maximizing strength. All of these advantages create the premier rim, but do effect the cost.
