The BSD ALVX AF+ BMX frame was developed together with Alex Donnachie and is aimed at riders who prefer a particularly agile street setup. The short 12.5 to 13-inch rear triangle makes quick direction changes and technical tricks easier. Together with the steep 75.5-degree head tube angle, this creates direct, responsive handling.
The frame is made entirely of 4130 chromoly steel. Additional reinforcements on the top tube and down tube, as well as the cast chainstay yoke, ensure stability in highly stressed areas. The 5 mm thick investment-cast dropouts feature integrated chain tensioners and a 14 mm axle opening.
The wide rear triangle provides room for tires up to 2.4 inches. The ALVX AF+ is designed exclusively for a brakeless build.
Three top tube lengths from 20.3 to 21 inches allow for adjustment to different preferences. Orange and olive green are available in color.
