Dahon Mu V-clamp - how tight?
I came home last weekend to notice that my handlepost seemed to rock left to right, but not front & back. It felt and sounded exactly like a threadless fork that's not clamped down tight enough.
So imagine my horror when I found out that it's actually the FRAME hinge that's loose! I've never adjusted the clamp since the bike was new, and the opening-closing action remained fiddly and loose.
Now this isn't covered by the manual, but I basically took the clamp off, loctited the threads, then reassembled the clamp and tightened it. Now when opening & closing the clamp there's quite a bit resistance at the middle of the swing due to the V-clamp hitting the frame. Past that 90-degree point and the lever swings home easily. But set the bolt any looser and the hinge won't hold steady.
So, how tight is tight enough? I'm afraid I might damage the (soft) aluminium frame with the steel clamp if I tighten it too much.
