【Get the same effect as a Speed Master Bearing for 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 making this a bearing significantly improves 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 attach a Canopus Speed Master Bearing (formerly Speed Star Bearing), right? That's why we created these grooved bearings. They have a simple shape, just the outer ring of an NSK stainless steel bearing with a groove cut into it (*), and because they don't have a heavy bearing holder like the Speed Master Bearing, the inertia is smaller, and the movement is more agile. They can be installed on the following models: TAMA Speed Cobra 310 series TAMA Iron Cobra 200 series There are also models other than the above that can be installed. Please inquire in the comments. ★Comparison video using TAMA HP300. https://youtu.be/ERCptkfbH7k?si=6_DiDntv70xZgAg_ ★Video showing that our bearings have the same low friction as Speed Master Bearings. https://youtu.be/i2p9vLpm7tg ●If you want multiple pieces for twin pedals, etc., please comment. (*) Although the outer ring of the bearing has been cut, the necessary strength for the spring roller is ensured. speedstar bearing speedmastar bearing
