Some of you might be interested to know that you can get bearings of different widths that will fit the RBC. You can also get MR85/W3, MR85/W4 and MR85/W5 bearings. The W3 will up the gap to 2.8mm, the W4 will make it 3.8mm and the W5 will make it 4.8mm. This makes for some pretty interesting responsive and unresponsive options for the RBC! ---

@MarkD @anon5341354 As a biologist, I feel it is my duty to inform you that RBCs are also called erythrocytes and therefore you could be missing out on an amazing opportunity to call this yoyo the “Erythrow”. Edit: or the “Erythrow-cyte”. ---

You, sir, are a marketing genius. Calling this the “Erythrow” could make it as big a hit with biologists as the Eppendorf Centrifuge rotor yo-yos from several years ago! ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/9/0/5/905a2fb9a62491c3113d2cbf12501bd1cb53ecc8.jpeg) ---
