The 2011 Eastern Thunderbird is right at the heels of Eastern's superstar Dirt Jumper/Pump Track/Urban assaulter Nightrain. Featuring the exact same frame, the Thunderbird is spec'd to be more affordable than the Nightrain but doesn't skimp on performance. It comes with easier-to-maintain Tektro mechanical disc brakes and the excellent Marzocchi DJ III fork.
