So far a great all-rounder
I ran one of the new Geax's today as a rear tire with an Ignitor front. It wieghed 690 grams. The Geax is a tall tire, just a bit shorter than an Bontrager XR rear, and about as wide as IRC Mythos. Fairly supple casing and a rounded profile. The central rib between the tread knobs is not as prominent as it appears in the pictures.
The Geax aired up without drama run tubeless with Stan's sealant and rim strip on a Bontrager Mustang rim. Run tubeless @ 29psi, the rolling resistence seems similar to an IRC Mythos rear. However, cornering and braking is vastly improved over a Mythos, Bontrager XR or ACX. Climbing traction is just short of an Ignitor. While it does not roll as well as a Nanoraptor, the Geax is quicker than anything else with "real" tread and volume beyond the 1.9 - 2.0 dimension. It doesn't look to be a great mudder, but I haven't found any yet to confirm that.
With the high volume casing, moderate rolling resistence, good climbing and great cornering traction, the Geax seems a great all-round trail or rough XC course rear tire. I'm really impressed so far. I'll be curious to see how it works as a front tire. No regrets with this purchase.:thumbsup:
