stephen m Posted September 24, 2022 Report Share Posted September 24, 2022 I have bought a pair of Betor Gas Aluminum Trial shocks and found the bush a little too wide to fit in my frame. The bush feels like it’s in a spherical bearing so I’m not sure if they press out? I emailed Betor and I’m not sure they knew what I was asking…. It needs to be just 2mm narrower - so I could grind it down in situ, but if it comes out I’d prefer to do that. Stephen Quote Link to comment Share on other sites More sharing options...
carl ekblom Posted September 26, 2022 Report Share Posted September 26, 2022 Betor often are around 24mm wide and have sort of rubber bush installed. I don´t know how to take it out undamaged. You may have to make your frame attachments wider to accept the shock. 24mm is quite normal. If the shock has a bladder (or Internal floating piston) inside (think most of them have) best is to mount it with the cylinder facing upwards in order to keep the unsprung weight low 1 Quote Link to comment Share on other sites More sharing options...

Stephen I had the same issue with a pair of Magical shocks I bought years ago for my Fantic twinshock, they were 24mm spherical where I really just needed 21mm. I just ground 1.5mm off each end of the sleeve, easy enough and worked a treat. Both 21mm and 24mm are common sleeve widths. Also, I think Magicals are glorified Betors, or something like that.

stephen m Posted October 2, 2022 Author Report Share Posted October 2, 2022 Thanks @fourex That’s what I’ve just started to do. I’m a bit concerned about keeping it square - but I’ll see how I get on 🙂 Quote Link to comment Share on other sites More sharing options...
