Subrosa MR3 Matt Ray BMX Frame Description:
The Subrosa MR3 Frame is built to handle everything Matt Ray throws at it, from huge gaps to fast, very technical lines, it’s easy to see why Matt Ray is becoming a big name in the sport. Matt has been a huge part of the BMX scene and our team for years, and the Subrosa MR3 Frame is a perfect reflection of his style and approach to riding. Designed around stability and control, the MR3 frame feels locked-in on big moves while still snapping through technical lines with ease. Constructed from tough 4130 Sanko chromoly, the frame features a heat-treated integrated headtube, double-butted top and downtube with gussets, Mid BB shell, integrated seat clamp, and heat-treated dropouts for extra strength where it matters most. Wishbone chainstays provide room for larger tires, while removable seatstay brake mounts keep the setup clean and customizable. Built with input from Matt himself, the MR3 is ready for riders who like to go big and ride hard.
