The untimely demise of the 26” wheel and the explosion of other wagon wheeled MTB disciplines has left the dirt jump and slope scene in its oversized dust. Finding a solid dirt jump tire has always been tricky, but these days it’s harder than ever. Riders are left choosing between older, and often heavy dirt jump specific tire designs, or running some sort of XC tire that’s light but doesn’t have a ton of sidewall support for over rotations or cases. Enter the Bontrager G Zero. Like most 26 tires, the G Zero isn’t a new design, but I’ll stick my neck out and say it’s one of the best dirt jump/slope tires on the market right now.
It’s pretty clear that the C3 crew played a large role in the development of the G Zero since the tire’s specs run like a Christmas wish list for dirt jump rats. The tire is constructed from a 120 TPI casing and weighs in right around 500 grams in the 2.2 width. The design features small fast rolling knobs that are tightly spaced and wrap around the tire and offer plenty of grip.
