【Product Specification】

• Triple bearing with a new spring system

• WARNING: The Spinning Bolt and the diabolo will be shaking. This can be balanced using hands. The diabolo and the Bolt have to be frequently tightened up
• The Spinning Bolt is a new product that is still in the development process. It's a complete product or a perfect product. You may use this to create new tricks 

【产品介绍】

• 此辅助器内含培林及弹簧，方便上手操作弹跳型动作
• 建议安装在三铃培铃扯铃使用
• 可做花式陀螺/类似直立铃招式动作
• 一个陀螺辅助器足以使用，因重量分布关系，扯铃运转时会如同单头铃那样旋转方向。随购买会附送一颗小螺丝，必须先把小螺丝装好，才能安装陀螺辅助器
• 扯铃运转时会抖动，可用手去触碰调整平稳，扯铃与辅助器也会经常需要锁紧
• 此产品仍在持续开发的阶段，还并不是完美的完成品，不过您可以使用它来创造新颖的扯铃招式
