Response system is the part of the yoyo which makes the yoyo spin and come back to your hand. Yoyos without a response system would just plumet to the ground without any attempt to spin. Most of the response systems have to be replaced regular and they’re an important factor in the yoyo performance. Here you can find all the different types of response systems and  at the end of the page we’ve made a useful table with the most common measurements…

Types of response system

1, Silicone groove pads – silicone rings with a sticky bottom side are the new standard in modern yoyoing. People call them “pads” for short and they can be found in both beginner and high-end yoyos. They are flushed with the yoyo body so they don’t get into the way of the string which improves both the sleep time and smoothness of the yoyo. There’s also a massive selection available so you can choose whatever suits you the best. They’re affordable hence widely available to everyone. However there are three things you have to be careful about:

  1. when replacing the response pads make sure that the groove is completly clean and doesn’t have any bits from the previous pad. Clean the groove thoroughly and remove any oil which might have gone into them. The pads might otherwise fall out.
  2. make sure that your bearing is not squirting out oil all over the string gap. Once some oil gets onto the pad, it’s going to absorb it and it’s eventually going to fall out.
  3. check what kind of pads your yoyo has. Manufactuers, sadly, didn’t agree on one standard size and there are about four different sizes. Vast majority accepts 19MM pads but there can be exceptions. Check out the table bellow with the names and measurements of the most popular pad sizes.


2, Fixed axle – we’re not sure we can even call it a response system, it’s a basic principle on which yoyos work. Narrow gap (usually wooden) creates enough friction for the yoyo to unwind and spin for a brief moment. These yoyos do not have a ballbearing, just a simple axle in the middle onto which you put the string. You can still perform tricks, it’s just a bit more challenging.

3, Starburst – this response system is moulded into the yoyo itself. It’s cheap to make and lasts forever (no need to replace it) and you can usually find it in cheap beginner yoyos or looping models. The biggest advantage is the fact you don’t have to spend any money replacing it, the disadvantage is that Starburst is too agresive and the yoyo looses spin very quickly. It’s also very responsive, sometimes even too much. But the sound these things make is irreplaceable!


4, Friction Stickers – these came long before the silicone pads. Flat stickers which are rubberised on top and therefore provide friction. They’re in a lot of Duncan plastic yoyos and their main disadvantage is that they need to be replaced quite often and their performance is changing all the time. Some people like the possibilites of adjusting the yoyo just to their liking by applying different kind of stickers. Nowdays it seems more and more that “Stickers” are a thing of the past. There are several options available:

  1. Friction stickers original – rubber surface which is very aggressive and responsive. Lasts the least amount of time.
  2. Silicon Friction Stickers – these have a silicone surface which lasts a lot longer and is far less responsive.
  3. Looping stickers – these are more durable than the original and provide even more response for looping yoyos.
  4. irPad stickers – only company which makes Sticker sized pads is irPad from Japan. They’re far superior to all of the above.


5, O-Ring – this is a speciality from YoyoJam. One rubber ring on each side of the yoyo. They wear out a lot less than the usuall response pads and they work great for beginner yoyos. And they’re easily replacable with silicone pads once you improve your skill enough.


6, Flowable silicon –  all response systems with a pad groove can be replaced with flowable silicone and a bit of skill. Check out your local hardware store for one.

Measurments of different pad sizes

Název Outside diameter Inside diameter Thickness Example
19mm – SLIM 19.0mm 14.3mm 1.085mm This is the most used pad size on the market today. Most of the yoyos with a C sized bearing use these: Duncan / YoyoFactory / C3 / Turning Point
21mm – BROAD 21.0mm 14.6mm 0.8mm Braod pads which are used by a couple of yoyos like for example: YYF Whip, G5+, C3 Mo-Vitation, etc.
YoyoJam / OneDrop 19.0mm 14.3mm 1.885mm These pads are thicker than the standard 19mm and they fit into most OneDrop and YoyoJam yoyos.
CLYW / SnowTires 21.0mm 14.3mm 1.885mm Larger and thicker pads for CLYW yoyos.
Small Bearing 16.9mm 12.3mm 1.5mm Pads for small bearing yoyos. Currently only sold by Duncan – SG Stickers small bearing size (yellow)
Duncan Stickers 22.0mm 12.3mm 0.385mm Duncan Friction Stickers. Compared to other response pads these are almost flat (very thin) and much broader. They’re used in some Duncan plastic yoyos although they’re slowly disappearing.
