GSport Ribcage Rim

The Ribcage has been one of the only rims to have true design breakthroughs in the last few years, since its introduction the competition has scrambled to catch up but still remain a poor copy, so if it doesnt say G-Sport on the rim, don't expect it to perform like a G-Sport rim.

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 a proprietary high strength aluminum alloy made specially for us in an on-site foundry . At 500 grams, the strength to weight ratio of the Ribcage cannot be matched. The 36mm width and 18mm height are also major factors in the design, spreading out the impacts and maximizing resistance to pinch puncturing.
