Dahon: Sure enough! Yours' has an aft slot. Just weird that it still has a plastic shim. Probably dahon using up stock of them before going to aluminum. Glad to hear you are upgrading that to aluminum, there is no more important upgrade. ***EDIT: UNLESS, it has already been replaced with an aftermarket shim that is *black anodized*. Look at it close, it should be evident if aluminum or plastic.***
Additional: I think the shim top should be under the clamp top (turtleneck), but looking at it closely, it looks like it could work either way. Notably, the rim on the top of my aluminum shim, looks to be a hair smaller diameter than the seat tube outside diameter, so the clamp is squeezing down on the seat tube, not just the rim of the shim, there's a tiny gap around the rim of the shim. After clamping the new shim in place, shining a flashlight in that area, should tell if the same.
hello, i can post pictures now hooray. yes it was indeed a plastic shim here's a photo:
the new shim is in. a photo below, not sure what you mean above re should be clamping down on the sim as well? do you mean it should be clamping down on the shim lip? i spayed some metal lubricant in there to help against corrosion, obviously there was already surface rust but nothing too bad. didn't need any glue, once its in it seems to grip on its own quite well and i haven't noticed any slipping yet or movement
regarding my handlepost flex issues, i followed your advice. the 10mm hex was already grip tight, but i loosened it and made sure it was gentle tightened no more than my grip. the flex or what felt like backward and forward movement was still there. i then decided to tighten the hinge mechanism itself, tightening the bolt post like in the below picture and video. it worked a treat. first i tightened it too much and couldn't close it, so i just worked with it until it felt like it was a good pressure but not a tight pressure and the handlepost is solid now. photo of the bolt I'm talking about below and video from dahon for others in a similar situation
video from dahon
I also straightened the handlebar as you suggested. other than that I've given the bike a nice cleanup with some muc-off solution and a spray with some metal lubrication spray. its looking nice and shiny. degreased and wet-lubed the chain.
only two issues I've come across. first the handlepost hinge has a little metal spring clip that it loose. i don't think loose enough to come off, but definitely not tight as it should be. I'm not sure where i would get such a replacement part. its tiny. see below its a tiny clip on the right off the bolt post
the other issue is i also want to tighten or make sure the main frame hinge is tightened right. i don't even know how that should feel as I've never had a new version to compare factory tightness to. any advice. I'm also not sure how to tighten it. in the photo below do i first loosen the screw on the outer side and then tighten the little bolt post you can see and then re tighten the screw? any help appreciated.
