June 5, 2015

Is it time for a new BMX frame? Are you looking for something shiny? What about something that will hold up to whatever you throw at it whether it’s park, street or dirt? Our friends at Radio Bikes dropped one of their Siren frames on our front door step to take a closer look at just what makes the frame so special. We figured it would be a good idea to give you guys a closer look, too! So let’s get into this one!

Let’s start out from the beginning! The Radio Bikes Siren BMX frame is made from seamless 4130 chromoly tubing with a 75-degree head tube angle, 71-degree seat tube angle, 11.6″ bottom bracket height, 8.3″ standover height and a 13.2″ chain stay length. You can find features like a CNC machined and heat-treated integrated head tube, gussets on the top and down tubes, butted top, down and seat tubes, a MID bottom bracket, an integrated seat post clamp, removable brake mounts on the seat tube with removable guides and a drilled head tube for gyro tabs, the seat stay bridges feature cut outs for a unique look while saving a few ounces, plenty of tire clearance for 2.40″ tires and thick CNC machined 14mm drop outs with extra machining for a unique look.

The 14mm dropouts on the frame are nice and thick with some extra CNC machining to give them a unique look and to shed a few ounces in low stress points.
