The WTB Nine Line 29×2.0 is developed with Cannondale, which will get OEM exclusivity for 2013, but it’ll be available aftermarket in January. Weight is 537g with regular casing, and a TCS tubeless compatible version is coming by end of year.
For 650B early adopters, the Wolverine gets a 27.5×2.2 option (685g), and there’ll be B-line 650 tire (name isn’t final) that’ll be similar in tread pattern to the Nine Line and another completely new tread in a 2.3 aimed at the aggressive Enduro tire. That design will likely become a DH oriented 26″ tire soon, too.
The Frequency rims add a 650 in the i23 size. Weight should be 463g and have a 23mm inside width. The Laser Disc i21 also gets a 650B option at 535g.
The Crosswolf is a recent introduction but is likely OEM only through next year. It has a UST bead and 60tpi casing with dual compound tread. Center knobs are stepped for fast rolling. 345g.
