Radio Siren Frame
Our do it all machine, the Siren is light and agile enough to not hold you back no matter what you ride.
Yet strong enough to hold up to the harshest of riding.
The lower standover and shorter chainstays make the siren the weapon of choice for many of our team for nearly 5 years now.
