It's a wonder how a long travel bike so adept at quick descents can also climb with lightning speed and acceleration. It could be due to the Fox 36 Vanilla R Open Batch fork and the Fox RP23 Kashima shocks. It could be due to the full 1.5" headtube and the relaxed 67-degree head angle. Or it could be the combination of all those great parts. The good thing is, you don't have to compromise anymore. Downhill, uphill, long rides, technical terrain--you can enjoy it all if you have Firebird XT/SLX Build.
