Transition Spire GX Gray Carbon Full Suspension Mountain Bike

Season:2021

Brand:Transition

Code:YRGremirPXG.BRC.ERIPS.12.

Take on the biggest terrain without the penalty, long travel doesnt have to mean single purpose

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, super 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. Don’t be fooled though, while it’s no one-trick pony, the Spire lives to push your limits. Get in-Spired.
