Ibis S35 Carbon 29″ 32h Rim

The S35s have it all. At Ibis they’re big advocates for wide rims. In fact, they helped pioneer the wide rim revolution back in 2014. Those rims helped inspire the new crop of 2.4”-2.6” tires that are popular today.  Wide rims work because they allow the tire beads to sit further apart. That wider footprint provides better tire sidewall support, which means you can run lower air pressure. This improves your traction, braking control, and also reduces rolling resistance over rough terrain.

Stan’s BST allows for a reduced rim cross section height making the S35 rims more compliant vertically. This not only improves ride quality but helps distribute impacts, giving us EWS performance at trail weights. The new carbon S rims are 9% better at resisting impacts than our already tough rims while also being lighter.
