Enduro courses. World Cup Downhill courses. It’s hard to tell the difference between the two these days. Well, right up until the point when you have to grind your way to the top of the absolute hairball descent—that would be enduro. And that is also where the new Firebird 29 enters the picture—with its speed generating 29er wheels and a penchant for kicking ass. The Firebird 29’s big wheels gobble up miles with ease, roll right over the gnar and add insane levels of traction to the mix. But this is no monster truck. The Firebird 29 is a lightweight machine that boasts a poppy, lively feel that long-travel 29ers have never possessed. Until now.
