The Axis X2 double pedal is a pro pedal all the way. The X2 uses a zero-backlash linkage mechanism for unmatched control. The pedal can be split apart and used as 2 independent singles. Superior performance is due in part to the use of multiple ball bearings, improved heel design, and the power of direct pull linkage. A self-centering spring assembly allows for easy pedal board adjustments. All parts are machined of structural grade aircraft aluminum and steel (no inferior cast parts), and the popular wide footboard design has been given a new brushed aluminum finish. On Consignment.
