Ibis goes wide with new carbon wheels

Published April 7, 2014

SANTA CRUZ, Calif. (BRAIN) — Ibis Cycles is launching a new carbon mountain wheel line with an emphasis on extra-wide 41-millimeter rims. The wheelsets, expected to be made available for the aftermarket in June, will be displayed at the Sea Otter Classic this week in Ibis' booth (#407).

Ibis says the wider rim allows riders to run lower tire pressures — 4 to 6 psi less — than on narrower rims without increased risk of tires folding over or burping. The lower pressure in turn delivers increased traction, better braking control and reduced rolling resistance, Ibis claims. The wider profile of the rim is also said to widen tire contact by 3 to 5 millimeters at the widest part of the casing.

The wheelsets are available in 27.5- and 29-inch sizes with a hookless bead, 35-millimeter internal rim width, hubs equipped with Enduro bearings, 7075 alloy nipples and 32 conventional triple-butted spokes. The 27.5-inch 741 wheelset weighs 1,650 grams and the 941 29er set tips the scales at 1,770. MSRP for both is $1,299.

Ibis is also releasing the 928 carbon 29er wheelset that uses a more commonly seen 28-millimeter rim width (22-mil internal width), weighs 1,580 grams, and will retail for $1,299.

The 741 and 928 are available now as upgrades on Ibis' Mojo HDR 650b and Ripley 29 bikes, while the 941 will likely become available for the Ripley starting in May. The wheels will be available for the aftermarket in June.
