For those looking to take on the biggest terrain, we give you the Spire. Ready to go up, or down anything you put in front of it. The Spire blends DH bike capability with mid-travel efficiency in such a way it's almost two bikes in one. A delicately tuned pedaling and pumping platform, supple beginning stroke sensitivity and all the travel you could ask for makes for a mind bending ride. Happily climb up to your favorite challenging descent, then cruise on over to your local flow trail and you'll be rewarded on both ends of the spectrum. This multi-trick pony lives to push your limits.
