Bead Socket Technology
By eliminating the bead hook and lowering the sidewall by 2-3mm they have reduced the weight of the rim. Some of this material can be used in the center part of the rim making it stronger and stiffer.
The curve of the rim sidewall is the same shape as the bead of the tyre so they fit together like a ball and socket joint. This design will help reduce the strain on the tire bead while creating a tighter seal.
By lowering the sidewall of the rim we also reduce the mechanical leverage the tire has on the rim. This will make the rim stiffer and last longer by eliminating flexing that can cause cracking.
With these short sidewalls the tire should not hit the rim and pinch flat as often as standard rims, either with or without tubes. This design will allow you to run lower pressures and use 4mm more of the tire than ever before. The tyre will have larger air volume giving you better traction.
