Transition Spire Alloy GX 2025 Bike

The Nimble Bruiser

Take on the biggest terrain without the penalty, Long travel doesn't 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 pedalling 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 favourite challenging descent, then cruise on over to you local flow trail and you'll be rewarded on both ends of the spectrum. Don't be fooled though, while it's no on-trick-pony, the Spire lives to push you limits. Get in-Spired.
