Frame Noise Improvement

Hey Thor!

I am having the same difficulty with the Silly word verification. Sometimes it makes me enter it more than once. And sometimes it says I entered something wrong even when I am careful and dead sure I did not!

Perhaps it is my VERY tight security, browser and cookie settings or flashcookie blocker but it is VERY tiring compared that "other" folding bike list I used to frequent:-))

Can we make it a bit simpler Mr webmaster??? Please

Hey Terry, Time is money too!

Imprezard, Good question. I'd start by saying that any time you have parts that have the opportunity to move against one another, you have a potential for squeaking. BB against frame, pedal against crank, seat post against frame, folding frame hinge against itself, folding handlepost against itself - all are possibilities. I've found that candle wax on the inside of the Radius handlepost and frame hinge can solve the squeaking in some instances. So you might try that.

So how can we avoid squeaking of our joint and handlepost? Well for starters, you design it differently: our frame and handlepost joints have a Norglide teflon bearing sitting between the stainless pivot bolts and the aluminum joint body. Next, you manufacture things to tighter tolerances. Tighter tolerances mean less movement. Our frame and handlepost joints are made by one of the top forging companies in Taiwan (the same company that makes the amazing bars, stems and seatposts for Syntace) and our machining tolerances are to 50 microns. 

I and the team have ridden most of the bikes, most ridden hard at demo days (with a healthy dose of dust and dirt thrown in), over the last month and I've yet to encounter a squeak from frame joints or handleposts. That is a first for demo day bikes. So although I can't say that our bikes will never squeak, I am confident saying that we'll be a lot less squeaky. 

I understand about not wanting bots and spammers to get on the list Terry!

That does not explain why it sometimes says [in red] that my verification is wrong. Perhaps one issue is the difficulty of discerning where there are spaces in the verification shown in the window? 

I am probably a participant in 10 forums and lists including being moderator on two lists with over 2000 members each and do not have these issues anyplace else. I also never see spam on the others although most are hosted by Yahoo or Google. Since you are using your own software perhaps it is "superior" but certainly much more aggravating. Nuff said. Hope things get better.

You are indeed fortunate. Some of the good things about the DaHon organization are still working.

I had a squeaking that would go on for a month or two (tried everything I could think of such as lubrication, tightening this or that, etc.) until I figured out it was simply the middle of the frame hinge screw (sorry for  not knowing the technical name) being slightly loose. I used a small wrench, tightened it, and the squeaking stopped. A squeaking sound can carry in the frame so it can sound like it is coming from anywhere. 

My Jack D7 will start to squeak after a few months, and I too play around with the screw in the middle hinge, as well as dropping a little bit of "Liquid Wrench" at the hinges between those gaps. It works great.

I also have a Mu P8 but the hinge design is different and I haven't run into any noise problem yet, so I am not sure if the same applies.
