※ This is a set of 2. 【You can get the same effect as Speed Master Bearings at about 1/3 the cost!】 Recent low-priced drum pedals are simple and easy to use, without adjustment mechanisms that confuse beginners, but unfortunately, the spring roller is still the old-fashioned resin ring. In fact, the part with the greatest friction resistance in a drum pedal is this spring roller section, and replacing it with a bearing will dramatically improve the pedal's movement. However, you might hesitate to spend 5,000 yen (10,000 yen for a twin pedal) on a low-priced pedal to install Canopus Speed Master Bearings (formerly Speed Star Bearings). So, we created these grooved bearings. They have a simple shape with only a groove cut into the outer ring of an NSK stainless steel bearing (*), and because they don't have a heavy bearing holder like Speed Master Bearings, the inertia is smaller, and the movement is more agile. They can be installed on the following models: Pearl P-1030 series (Eliminator Solo) Pearl P-930 series Pearl P-920 series YAMAHA FP7210A YAMAHA FP6210 TAMA Camco (reproduction HP35B) They can also be installed on other models. Please inquire in the comments. ★ The following is a video comparing before and after replacing the bearings. https://youtu.be/f0UEkBX1t_0 ★ This video shows that our bearings have the same low friction as Speed Master Bearings. https://youtu.be/i2p9vLpm7tg (*) Although the outer ring of the bearing has been cut, the necessary strength for a spring roller is ensured. speedstar bearing speedmastar bearing
