When IBIS set out to improve their previous wheels, one of their goals was to make them even lighter and stronger. That wasn't easy. To do it, we needed to reduce the height of their beadwalls. The shorter the beadwalls are, the less likely they are to bend and break. Stan's already uses this technology in their existing product line, so they reached out and asked if they could collaborate. The S-wheels use their patented BST technology, which helps them reduce their beadwall heights while optimizing tire fit and mounting.
An asymmetric rim means that instead of the spoke holes being drilled through the center of the rim, they're slightly offset. Doing this allows us to improve the bracing angle of the spokes. Because their rims are so wide we get to make them even more offset than normal. The larger offset allows IBIS to tension both sides of the wheels nearly equally, which results in a stronger and more durable wheelset.
