The Sunday Darkwave BMX frame in a 21.25" top tube is built for modern street and park riding where front-end abuse, repeated impacts, and quick drivetrain adjustments are part of the routine. Its all-chromoly construction, dent-resistant Wave down tube, and clean integrated details deliver a frame that stays tight, tracks predictably, and keeps a refined look in matte black—even after hard use.
Built-in advantages for real-world BMX riding
Wave-shaped down tube (1.45" diameter) - Helps resist common down-tube denting that can weaken the front end after repeated hits and missed landings
Broc Raiford signature geometry - Tuned for responsive handling and stability at speed, suited to technical street lines and park transitions
Hollow 8mm dropouts with integrated chain tensioners - Strong, weight-conscious rear end with easier wheel alignment and faster wheel removal during gear changes and tire swaps
Miter-cut top tube junction - Creates a more precise weld interface at a critical stress area, supporting long-term durability
Removable U-brake mounts and gyro tabs - Clean, snag-free setup for brakeless riding, with the option to add brakes/gyro hardware when needed
Integrated seat clamp + tapered chain/seat stays - Streamlined fit and finish with improved chain clearance and a cleaner, less cluttered rear triangle
