I bought this Japanese Canopus Speed SS-5000 bearing for a single foot with a single chain DW 5000AH. Before installation, the foot control was much worse, now it is completely different, softer, smoother and faster, for all those who are wondering whether it is worth it, I say that it is worth it, although it is not cheap, but very effective. The foot has a buttery feeling as in the DW9000, except that the mechanics of DW5000 I recommend it with a clear conscience, this product is worth every €uro.Thanks Canopus and Thomann for this pedal upgrade here in Europe.
