BMX Subrosa MR1 Frame (Matt Ray Signature) | RideHub

The Subrosa MR1 Frame is Matt Ray's signature BMX frame , designed for riders who demand stability, durability, and precise control . Building on his previous model, Matt has made several key improvements that improve handling and frame durability.

The biggest changes are an increased standover height (9") for better stability and a raised bottom bracket (BB) height for more pop during tricks. An extended dropout slot allows for compatibility with more gears and easier rear wheel removal during repairs.
