Description

The G-Sport Ribcage Rim 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 G-Sport on the rim, don't expect it to perform like a G-Sport rim.

Features

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.

The Ribcage is stronger than the Birdcage.

Features

500 grams, no weak spots. A proprietary high strength aluminium alloy, made in G-Sport's own foundry, gives the Ribcage its strength to weight ratio.
Patented ribs at the spokes. The spoke holes are reinforced with patented ribs that support the sides of each nipple and remove the chance of nipple pull through.
Built for cross over lacing. Each spoke runs from one side of the hub to the opposite side of the rim, increasing the angle and the lateral strength.
Thick outer walls. The outer walls are extra thick to resist case dents while the other walls stay thin to keep the weight down.
36mm wide, 18mm deep. That profile spreads impacts out across the rim and maximises resistance to pinch punctures.
