※ 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 by using a bearing here, the movement of the pedal will be dramatically improved. 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 (＊). Since they don't have a heavy bearing holder like Speed Master Bearings, the inertia is small, and the movement is more agile. They can be installed on the following models: TAMA Speed Cobra 310 series TAMA Iron Cobra 200 series Other models may also be compatible. Please inquire in the comments. ★ Here's a comparison video using TAMA HP300, which has the same parts around the spring. https://youtu.be/ERCptkfbH7k?si=6_DiDntv70xZgAg_ ★ Here's a video showing that our bearings have the same low friction as Speed Master Bearings. https://youtu.be/i2p9vLpm7tg (＊) Although the outer ring of the bearing is cut, the necessary strength for a spring roller is ensured. speedstar bearing speedmastar bearing
