Hahaha. Good response here. Maybe not the best advices, but still. Anyway. I managed to open it. I was actually jus me pulling and pushing in the wrong place. Unfortunately I could only open the main chamber. The rebound valve sits in the other (negative?), so I could not inspect why it did not work. Was hoping to fix it to one in spare (got a new replacement from Begode.) An observation. Many of the clonking sounds I had even on normal riding (not top and bottom out) are hugely reduced when using the rebound valve almost closed. I thought play in the linkage system would not not matter so much since it is always pressurized. But after this I suspect the linkage play to be a bit part of the clonking sounds problem. Anyone who changed to Kuba linkage noticed less annoying sounds as well? Quote Link to comment Share on other sites More sharing options...

No weird sounds with Kuba linkage and Rockshox shock (Kuba is not compatible with stock one different diameter fastener 12.7mm). Quote Link to comment Share on other sites More sharing options...
Lilvodka Posted November 16, 2022 Share Posted November 16, 2022 There’s new firmware update. I tried it and get confirmation of successful update, then turn wheel back on and hasn’t updated. Was hoping it would sort out the play issue. 1 Quote Link to comment Share on other sites More sharing options...

(Does the shock use all this travel, before the EUC suspension hits its endstops?) No. The Russians made a graph for the linkage, and they stopped just before 25mm suspension travel. I tested to 30mm just to see the direction of the graph beyond... What I am saying is that less than 25mm suspension travel gives 75mm wheel travel. 0-25mm is the most interesting measurement. This the first proto I am testing in the rig. It is 23milli litre in volume. 20mm high. I will make one that is 30milli litre in volume as well to measure the difference, but my TPU is all out With this reducer mounted I have 37mm suspension travel available. Only need max 25mm. 🤪 Edited November 17, 2022 by EUCzero 2 1 Quote Link to comment Share on other sites More sharing options...

EUCzero Posted November 20, 2022 Share Posted November 20, 2022 I do not think any shock is designed to allow use of 100% of its range, but less than half is BAD. Unless that is how to shock is designed to work best. But the Begode shock do not work at is best this way, It becomes almost linear, the the linkage is also linear. So.... I will do more tests today. Keep you all posted. With a few different reducer sizes. 1 2 Quote Link to comment Share on other sites More sharing options...

EUCzero Posted November 20, 2022 Share Posted November 20, 2022 The 27m.litr volume reducer helped a LOT. but still not perfect. But I ran into some issues when I wanted to mount in into my new replacement shock from Begode. Hehe. The new shock have a few improvements, that made it more difficult for me. First it was locked with red thread lock. Probably to prevent leakage. I read some have leaking suspension. Next, there was a foam pad inside, dripping of oil. Probably there to keep the oil inside, lubricating the shaft on every compression. These two things made it a bit more difficult installing the volume reducer. Also.... there is something going on in the second chamber. Now I have to pump the shock up to 70psi for it to extend all the way. If I release the pressure, it will detract. This is not the behaviour the old shock had. It like I now need 70 psi higher pressure than before just to compensate. So I do not have any conclusion yet. In the test rig it was fine. Test values perfect. Very nice progressive curve. But I must have done something to it after. Quote Link to comment Share on other sites More sharing options...

Thank. So my new shock is different it the way that my old one probably hade a defective neg. chamber. The rebound adjustment did not work, and the top out would always be violent. Both the rebound adjustment and the negative chamber should prevent that. Also means I need different psi on the new one to get the same dampening. Anyway. I went for 300psi. Still cushy on small bumps. No bottom out on 30-40cm hard drop. Before the volume reducer it did. I can really feel the progressive damping now. I will put the stl files on thingiverse.com tonight.

Yes... Be VERY careful using the metal plyer still. Could be small charges in other capacitors on the board as well. So sometimes some tape around the peak on the plyer is a good idea. Instagram cut the video when I drained it by powering on. I am told that on some boards you have to remove the upper main board to find the small one. But on my wheel it was super easy. 1 2 Quote Link to comment Share on other sites More sharing options...

EUCzero Posted November 21, 2022 Share Posted November 21, 2022 (edited) It is live. A 27 milli litre volume reducer specially made for the begode Master is now on thingiverse.com Print in TPU 100% infill. A have desgned it, but YOU mount it and use it an your own risk. Pressure inside the shock will now rise more progressive, and therefor not bottom out so easy. BUT.... the pressure WHEN and IF you bottom out will also be higher. Chance Hinz have a start pressure of 420psi (very high in my opinion) without a volume reducer, but that does not mean it is made for it. With the volume reducer you should probably NOT pump it that high as it will rise much quicker when compressed. The newest shock from Begode also had an oil drenched piece of foam inside. Print the "volumereducer_mountingplate" and use it to compress the foam and keep it out of the way while mounting the volume reducer. Her you find the files: https://www.thingiverse.com/thing:5647308 A video of the mounting process will come, but for now, use the Instagram video showing one of the prototypes.https://www.instagram.com/p/ClCY4jkMzla/ Edited November 21, 2022 by EUCzero 1 2 Quote Link to comment Share on other sites More sharing options...
