BSD ALVX AF+ FRAME

BSD ALVX AF+ Frame – Alex Donnachie Signature BMX Frame

The BSD ALVX AF+ Frame is the latest evolution of Alex Donnachie’s signature frame, designed for the most technical street riders.
It keeps the super-tech geometry and ultra-short rear end of the original ALVX, now upgraded with a new invest-cast chainstay yoke that improves tire clearance and makes the rear triangle even stiffer — and it looks incredible too.

Built from Sanko Japanese seamless 4130 Chromoly, the ALVX AF+ offers top-tier strength, low weight, and unmatched responsiveness. This frame is made to handle anything from ledge lines to heavy street combos with total precision.
