Funky sizes (or when stock is wiped) I usually look on McMasterCarr. They have a bearing section where you can filter by the specific dimensions. Good reference here if ever needed: > **[Ball Bearings](https://yoyo.fandom.com/wiki/Ball_Bearings)** > > Ball bearings, in the context of yo-yo play, were introduced in the early 1990s. They are used to reduce friction while the yo-yo is sleeping. A ball bearing yo-yo can be played in two extreme states. One configuration involves using a thick... ---

All I see is the metric system… does anyone more intelligent than I have the specs for a Size E bearing? ---

There is a Custom Mag, Custom Reactor, and TK SB2 all for sale by the same dude in Cincinnati on FB Marketplace that caught my attention. Around $50 a piece asking prices though. Don’t know if that’s good or bad. ---

Great deal on the TK SB2 in my opinion. The Custom stuff is good, nothing wrong with them inherently, and as mentioned, aesthetically look awesome, but I just think there are some designs that do it better from a performance standpoint, especially since their time. All tastes are a bit different though, so, grain of salt and all that. They’re still fun for certain. ---

I’m not finding the exact size; it might be the same price to just buy a Tigershark and snatch the bearing from it. ---

I am _kind of_ looking for a Reactor. The financial situation at home is kind of funny, we aren’t struggling, but we don’t have enough for me to earn some money without feeling bad about it later. thanks for the offer, but I can’t right now, I hope you understand. ---

Did my first “Mod” today, I satined a Freehand One! I didn’t have a drill, so I just threw the yo-yo, and sanded it while it was spinning. 🤣 Results: ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/f/0/0/f002ac43a37ccf2636de1b7adf271c61e9132281.jpeg) ---
