※ This is a set of 2. 【You can get the same effect as Speed Master Bearings at 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 making this a bearing greatly improves the movement of the pedal. Therefore, many people seem to be installing Canopus Speed Master Bearings (formerly known as Speed Star Bearings), but Speed Master Bearings are expensive, aren't they? Even at Sound House, the industry's lowest price, they cost over 5,000 yen. Many people hesitate to spend 5,000 yen on a pedal that costs in the early 10,000 yen range. That's why 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 Speed Master Bearings, so the inertia is smaller and the movement is more agile. They can be installed on the following models: YAMAHA FP720 YAMAHA FP820 YAMAHA FP810 TAMA Camco (DP120 initial model) ★↓ Here's a video comparing before and after replacing the bearings. 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 speedstar bearing speedmastar bearing
