EUCzeroBottomout - Begode Master

thingiverse

!! Update. 26.Now 2022 New PERFECT ;) size 23 good to go. Full travel on the the sliders now. (If using the original 5mm o-rings Begode have put on the sliders.) Maximum height of the volume reducer should be 20mm tall. The new 23 milliliter is 19mm tall. Had a very good test ride yesterday (26.Nov 2022) with flat landing jumps and all, and only bottom maxed the suspension once. I do suspect that if you jump down long staircases or similar you will still bottom out, but never close to as hard as before. You can always increase the pressure, but then you loose your sag and small bump dampening. PS.... the T4 use even more of the shock travel, so the size 23 will probably be to tall for it. Will make even shorter ones that could also be used for the T4. But I need some measurements first. !!!!!!UPDATE 25.Nov 2022. STOP USING the old sizes 27, 29 and 31 milli liter. They where to tall, and the shock could bottom out before the sliders. Maximum height of the volume reducer should be 20mm tall. ........ The Begode Master is infamous for bottoming out very easily. One fix is to change the whole suspension linkage as well as the shock itself. A very expensive mod. This mod is almost free if you have access to a 3d printer and 30g TPU95A. The linkage on the Master is tested to be very linear. Air shocks itself are known to be progressive, and this would compensate for the linkage. But Begode chose to only use the first 24mm of the 70mm long travel shock. So int only use the linear range of the shock. Reducing the volume of the main chamber would make it more progressive. This is a knows way to mod air shocks. So it is not something new. But finding a volume reducer made for this shock is probably not easy, so I designed one myself. 27milli liter worked very good for me. And I think it will work for most. UPDATE!!!!! 25.Nov. 2022 27 milli liter is not enough for jumping. Riding is good, but for jumps... So. I made two more sizes. None of them have been tested yet while riding. 29 and 31 milli liter. We are getting close to as big as I can go for it to still fit inside the shock without it hindering the full movement of the sliders. I could probably go to 33 as well, but then it is stop. PS.... Begode just released new linkage for the Master. DO NOT USE THIS REDUCER WITH THAT NEW LINKAGE AS I DO NOT KNOW THE TRAVEL ON THE NEW LINKAGE YET!!! Video on how to mount it: https://www.youtube.com/watch?v=JhICbhTWBXQ Print in TPU95A, as TPU can take the oil that is in the shock. It most also be a bit flexible to mount. Print in 100% infill. No air pockets. Pressure inside the shock will rapidly change when used. It is easy to install. But a little fiddly to uninstall. To help with that I designed some holes for better grip pulling it out. I have two shocks from Begode. The latest I got delivered had a foam piece drenched in oil inside. This foam made it a bit more difficult to mount the reducer. If you have this foam print the mounting plate as well. Use it to compress the foam to keep it out of the way while mounting the reducer. And then remove the mounting plate when the reducer is in place. https://www.youtube.com/watch?v=JhICbhTWBXQ https://www.instagram.com/p/ClCY4jkMzla/?utm_source=ig_web_copy_link
