No Onedrop yoyo I’ve ever owned has felt right without a 10 ball in it. ---

> [@AaronW](#): > > I believe the reason OD hasn’t used a concave bearing is out of respect for Frank Difeo’s patent on the design, or others patents. Instead of buying a bearing, that would increase the price of their yoyos, or buy something that is ripping off Frank’s design and not rightfully paying Frank, they have decided to use their flat bearing. Yes this is 100% correct and was confirmed… _at some length_ … in their latest Q&A. They also said they make a slightly looser bearing seat so it is easy to change the bearing and that is DEFINITELY true :wink: I also recall someone saying that a strong centering bearing kinda removes the play differences of some yo-yo designs, so in that sense it reduces your “feel”. I’d also add that there are really three kinds of bearings: 1. Totally flat 2. Mostly flat (CT) 3. Strongly centering (KK full concave, V shape, string groove, etc) The difference between #1 and #2 is pretty minimal IMO, you get almost all the benefits of flat with the major benefits of concave. So to me, full flat is kinda… obsolete, TBH. The “moral” argument doesn’t hold water because the CT is a _better technological innovation_ than pure concave (KK). But I’d also add strong centering bearings indeed have a strong effect on play, and shouldn’t be put in unless you agree that you kinda want an opinionated centering behavior in your yo-yo! ---

Good old bearing opinions. I like them all. I find that in different yoyos I like different bearings. The 420 only feels right with a ten ball for example. If I could only have one type of bearing it would be 10 ball. ---

Same here - can’t stand grooved bearings. Prefer flat or CT depending on the yoyo. ---

I don’t have a super amazing range of bearings. I mostly have 8 ball CTs I pulled from yoyos I got. I have like 5 10 ball CTs, 1 kk, 1 knock off kk, 1 groove bearing, a couple no brand flat bearings, and like 2 OD bearings so my bearing tastes aren’t too broad, though I do like what the OD bearings and CTs I have that work have to offer :yo-yo: ---

Overview of shapes > [@History of / differences between different concave bearings?](https://forums.yoyoexpert.com/t/history-of-differences-between-different-concave-bearings/290973): > > [image] OK so there are a variety of concave bearing shapes: obviously, pure smooth concave, the “O” of bearing shapes if you will concave but with a center channel indent for the string angled down to the middle, the “V” of bearing shapes if you will the most common type: flat in the center, but the sides angle up, the “H” of bearing shapes if you will. I’d say 80% of the “concave” bearings I encounter are this type the least common type, a combination of V and H, angled steps i… - Flat is… flat. Simple. 🙂 - CT is flat in the middle, angled up slightly on each end. I would kiiiinda put DS and “pixel” in this category as well (four “steps” meaning the middle is relatively flat and the sides are angled up more). - Pure concave, V, and string groove are all strong centering and conceptually really do _force_ the string into the center at all times. ---

I feel you on this. I haven’t tried any of the A’RT’s yet, but based off of their minimalist organic designs, it seems like they were made to be played on a flat. DS bearings are my number 1 choice in my competition yoyos; best performance bearing I’ve ever used. ---

I can get that some people enjoy them. Im not one of them. I have replaced the bearing in every OD i own. Not to mention i have had a problem with most of them becoming really noisey despite persistent maintenance. Ill happily keep buying OD and putting my preferred bearing in em’. They are worth it. ---

I appreciate the One Drop guys input on this, and of course all my fellow forumers. I totally ‘get’ where OD is coming from on this; it’s _their_ product, they ship it with the knowledge that many will swap it for their preferred bearing, and it’s a bit of a respect thing. I respect all of that. That being said, I believe the evidence to be pretty empirically conclusive that there are better bearings out there (G2 Boss and Buddha Ripples come ro mind, NSK gold KK) and since OD is one of the greats, it makes sense to me that they would possibly want to maximize potential of their throws. Does my position make sense? ---

Not quite… So for clarification, your saying that in your opinion, OD should want to maximize the potential of their yo-yos by shipping them with non-flat bearings? ---

I’m not trying to tell a successful company what to do at all, esp considering I have no experience in such things. I was merely explaining my position, my rationale. The company has a great product, makes sense to me if I had a great product, and an opportunity to make the product _even greater_ by maximizing potential through implementation of superior internals, I would do so. ---

Just a little more perspective offered from this same conversation not to long ago: > [@Flat Bearing](https://forums.yoyoexpert.com/t/flat-bearing/299490/57): > > Well if we shipped with concave bearings then anyone who wanted flat bearings would have the same problem. This critique can be made of anyone making yoyos as I don’t think anyone ships with both (which would mean you are still paying for one you don’t want). Our customers seem to be about 50/50 on which kind they like so not matter what half the people will be replacing the bearing. > [@Flat Bearing](https://forums.yoyoexpert.com/t/flat-bearing/299490/59): > > I completely understand! In the end, it all boils down to personal preference, not really something that a yoyo company should have to deal with, unless there is a general consensus within the yoyo community. > [@Flat Bearing](https://forums.yoyoexpert.com/t/flat-bearing/299490/60): > > Totally slight_smile And the way we deal with it is to put a high priority on getting the bearing post size correct (not an easy thing to do) so that customers are able to easily change the bearing.
