Nearly twenty years ago, Stan’s NoTubes pioneered the first modern tubeless system. And they’ve never stopped innovating. To develop their new S-Wheels, Ibis worked with Stans to combined their expertise in wide asymmetric carbon fibre rims with their patented Bead Socket Technology (BST) to create some of the lightest, strongest, and best performing rims available today.
IT'S ALL IN THE RIDE
Stan’s BST allowed Ibis to reduce the rim cross section height, making the 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 their already tough alloy rims while also being lighter.
WHY WIDE?
Ibis are big advocates for wide rims. Ibis 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.
NO PROPRIETARY PARTS
Ibis build their wheels with readily available parts, so you can source replacements wherever you go. By using standard J-bend spokes and external square nipples, they’ve also made their wheels easy to service.
IBIS HAVE YOUR BACK
Ibis rims are backed by a lifetime warranty. If it’s their fault, we’ll fix it. Ibis also offer a low-cost “accident replacement” program, just in case you drive your bike into the garage…
