We are thrilled to announce the launch of our latest product, the BDH H1SQ Dual Mode Mechanical Shifter.

This innovative dual mode shifter offers two independent mechanisms aligned into one chassis, providing high-end race car gearing for Professional Sim use. 

Originally based on the Ford Escort MKII Rally cars gear shifting mechanism our shifters have evolved and can be adapted to your personal preferences using BDH "Tensioning Technology" to ensure that you get the feel that you are looking for.

Our Shifters undergo 100's of hours of live testing, weighing 4kg, the H1SQ is built to undergo the stresses you'd expect on track. Click on the video in the media role above of Dave explaining more about the shifter.
