downright fun. The front end comes off the ground easily,
and the rear end is quick to follow. When we think of fun
and “flickable” trailbikes, this will be the new benchmark.
TRICKS, UPGRADES OR TIPS?
The Cane Creek AngleSet is a finicky beast. It creaks
and cracks when it’s not set up properly, and it’s almost
impossible for anyone but a Cane Creek-trained professional mechanic to get it right. We’re torn here, because the 1-
degree slacker head tube angle helps handling, but it’s not a
The SRAM XX1 is an impressive first-generation drivetrain that could revolutionize this category of long-travel trailbikes. That said, the shifting is solid but not perfect. Fitting
11 cogs in the cassette results in slightly temperamental shifting, no matter what the testing charts and graphs say. While
this drivetrain shows incredible promise, the design will no
doubt see further improvements in the next few generations.
We’ve already made it clear that we would recommend
the Firebird. It’s an outstanding all-mountain bike that can
be pushed into enduro or Super D riding and racing with
ease. It also has the versatility to do some light-duty downhill in the hands of a skilled rider. Our build kit proved to
be a perfect match for the Firebird, but it comes at a price.
If you’re into the SRAM XX1 kit, you’ll certainly be an
early adopter. It will see improvements the same way that
any technology does, but even this first generation of the
XX1 works really, really well. ;
Project build: We don’t often get to hand-pick the parts for
test bikes, so this was a treat. This one is dressed with
SRAM’s XX1 build kit, and the best-matching suspension
setup we could dream up.

Project tweaks: The XX1 kit feels like it’s purpose-built for long-travel trailbikes. It worked nearly flawlessly throughout the testing
period, but it’s a first-generation setup. Still, we’re impressed.
