Quality in PRESION footwork is excellent.
the double is not at all intrusive and the spring system is amazingly simple but impeccable reliability. In addition, when we found his set, you can block it with a tie.
The quality of the sole Delta has been proven, but with a DW 5500 double pedal from the first generation, we can say that DW has changed its sole optimally.
Try it, but unfortunately that's the kind of pedal, or, when set foot on it, it seems difficult to go on another. While other brands offer excellent models too.
