Just finished building up my new On-One 456 EVO. The parts swap fought me every step of the way ... but it turned out great! Hit my local trail today for it's first time out. Handled the 12 miles of technical-twisty-singletrack like a champ. Felt nicely compliant for being 4130 chromo ... then again I am going from Kona's aluminum. Although it weighs in at 29lbs ... it's so well balanced it feels much lighter when lifted by hand.
