【Get the same effect as a Speed Master Bearing for about 1/3 the cost!】 The YAMAHA FP720 was designed in the 1980s, so the spring roller is just a metal or 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 significantly improves the pedal's movement. Therefore, many people seem to install Canopus Speed Master Bearings (formerly known as Speed Star Bearings), but Speed Master Bearings are expensive, aren't they? Even at Soundhouse, the industry's lowest price, they cost over 5,000 yen. Many people hesitate to spend 5,000 yen on a pedal that costs around 10,000 yen. So, we created these grooved bearings. They have a simple shape, just a groove cut into the outer ring of an NSK stainless steel bearing, and they don't have a heavy bearing holder like the Speed Master Bearing, so the inertia is smaller and the movement is more agile. Compatible with the following models: YAMAHA FP720 YAMAHA FP820 YAMAHA FP810 TAMA Camco (DP120 initial model) ★↓Here's a video comparing before and after replacing the bearing. https://youtu.be/q58pPB_cgrc ★↓Here's a video demonstrating that our bearings have the same low friction as Speed Master Bearings. https://youtu.be/i2p9vLpm7tg ●If you want multiple pieces, please comment. speedstar bearing speedmastar bearing
