It's right for you if... You want one carbon trail bike that can take on every adventure, from flowy singletrack to the gnarliest descents and most brutal climbs. You don't mind sacrificing a little on the parts so you can get the best frame right now.

The final word Full suspension control on a lightweight and trail-tough carbon frame makes for a fun and fast ride.
