For Volumes 20th anniversary we wanted to bring back a classic frame. Brian Castillo’s signature Dinosaur! This frame originally came out in 2001! Brian knew what he wanted back then, with it only being available in a  20.5” top tube (Exactly as he rode it himself) and dropouts borrowed from a previous years Volume frame. Even today, Brian’s influence on bmx still shows in riders around the world, whether they know it or not.

This frame has evolved over the years and is now available in black chrome with a 21” top tube. The frame features a double butted front triangle with top and bottom gussets for added strength, wider bottom bracket shell for bigger tire clearance, 13” chainstay (slammed), 9.25” standover, classic solid 5mm thick dropouts, removable seatstay brake mounts, built in seat clamp, CNC’d seatstay bridge and a classic wishbone chainstay junction!

Despite its decals and subtle hints of the popular mid school bmx era, all the way from the streets to the trails, this beauty has all the modern goodies you could want.
