+1 to pretty much everything Michael Jackson said....I have the GNCC's front and rear on my Banshee and they really hook up. Rubber compound is a bit soft but doesn't wear too badly if you keep 'em off the culm banks. The softness is more than likely part of the reason they hook up so well though. Even on muddy/sloppy trails they really work well. Would absolutely buy them again, except I might get the 21 inchers for the back for a bit more ground clearance (like Mike said the 20 inchers are kinda small).
