Hello Dave from On-One is the sickest steel hardtail for properly insane bike park and DH action
The Hello Dave is a bit of an anomaly. Not many hardtail mountain bikes enable you to ride anything you dare point your front wheel down. With a long and low frame, aggressive angles and a 150mm fork, you wont ever feel held back by high speeds, big jumps or steep chutes again.
