The S35 Aluminium Rim is an awesome, all-around rim with an unbeatable value. 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, they need­ed to reduce the height of the 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 Ibis reached out and asked if they could col­lab­o­rate. The new S-wheels use Stan's patent­ed BST tech­nol­o­gy, which helps reduce the bead­wall heights while opti­miz­ing tire fit and mounting.

The S35 Aluminum Rims feature an asymmetric design. 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 for the improvement of the brac­ing angle of the spokes. Because Ibisrims are so wide they are more off­set than nor­mal. That larg­er off­set allows both sides of the wheel to be tensioned near­ly equal­ly, which results in a stronger and more durable wheelset.

Ibis rims are backed by an impressive sev­en-year war­ran­ty. If it’s their fault, they'll fix them.
