Welcome to the wide world of Ibis rims, what we refer to as The New Normal and The New Wide.
941 rims are 27.5 and 29er rims with monster 41mm widths that deliver super tire stability even with large tires at low pressure.
Wider rims are better than narrow rims. A wider rim delivers better sidewall support so you you can run lower pressures in your rubber. Lower pressures do several beneficial things, including increasing the contact patch, which results in better traction. Tires mounted on wider rims don’t burp as easily. Running lower pressures on varied terrain actually reduces rolling resistance. Wider rims are stronger and stiffer. With increased traction comes increased braking control.
Go Big, Go Small
Big - If gravity is your thing, bigger tires and lower pressures equal more traction. The problem is, you can only go so low with large tires on narrow rims before they become unstable. Enter the wide rim. Select the pressure you want without having to over pressurize the tire to control stability and burping.
Not-so-big - If you’re leaning more toward XC use, you can actually go down one tire size and achieve the same or higher levels of traction and performance, only at a reduced overall weight.
Less Tubeless Burping - Wider rims dramatically reduce the incidence of burping. With wider rims the tire sidewall can’t exert as much force on the bead to unseat it and allow air to escape.
