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

Strong and Lightweight

At 500 grams, the strength to weight ratio of the Ribcage cannot be matched. The entire design revolves around the use of a proprietary high strength aluminum alloy made specially for us in an on-site foundry. It is a lightweight rim that can take anything you throw at it.

Patented Ribs

With the Ribcage, the spoke holes are re-enforced with patented ribs that support the sides of each spoke nipple and eliminate the possibility of nipple pull through under even the highest loads.

Superior Lateral Strength

The rim also features cross-over-spoke lacing, where each spoke goes from one side of the hub to the opposite side of the rim for an increased angle and therefore increased lateral strength.

Dent Protection

The outer walls are extra thick to protect against case dents, while the other walls are extra thin to keep it light. The 36mm width and 18mm height are also major factors in the design, spreading out the impacts and maximizing resistance to pinch puncturing.
