Headset may be over tightened or need servicing or replacing. Try loosening a little and if that solves the problem without any looseness or rocking, happy days!

You'll have to find one with the correct pull rate as your shifter. I'm guessing the Sora would work.

RD hanger would be specific to your bike. They come with all shapes and sizes. Why do you need to replace it? Damaged?

A forummer bought a 16 inch rims from me and has find difficulty in sourcing the 20/20 holed hubs for the rims. It's not available in Malaysia actually but it can be bought online from Taobao, China. I have no idea with regards to the said forummer's front fork width as there are 2 different widths. One as used by Dahons and Terns are 74mm and the other the usual 100mm (usually those with disc brakes). The 74mm offers more rigidity and stronger as the spokes are not too angled from the rims. That's why Dahons and Terns choose that width, probably.

There's another option , though. You can get the front hubs (20 holes) from here if you are using 74mm.

and if you are using 100mm forks, you can get the adapters here.

As for the rear, you can go for either a 24 hole or a 32 hole ones and skip a few holes while lacing. The distance is so small, I don't think it will affect the truing of the rims and more so because the rims are only 16 inch diameter. So, use with confidence. The only drawback is.................most LBS are not interested to do it as there might be a few spokes modifications. You might need to adjust the length of the spokes.

I would suggest though that you take this set. It is the 24 for the rear and the 20 for the front. This eliminates a lot of problems.

And if you want to use the regular , more easier and off course cheaper as it is common 32 holes for the front and rear, I have drawn the spokes lacing patterns. The red dots on the smaller circle are the SKIPPED holes. Both the 24 and 32 holes are fine if you look at the lacing of the spokes. Shouldn't be a problem. Good luck !

This is the 24 holes lacing.



and.............this is the 32 holes lacing.



If you have contacted me earlier, I could have done it for you but I am now in Taiping, so it's a bit hard. If you want to mod the spokes yourself like I do, get this ; The size of the spoke nipples are a bit special though. Most nut and bolts store stocks only 2,3,4,5,6mm etc but not 2.5mm which is the size for the spokes. I got it from Central Nuts and Bolts in Jalan San Peng, K.Lumpur. You get longer spokes, for mountain bikes, these are the easiest to get anyway and then measure and cut to length needed and tread it.

There is no RD hanger on my MU, I assume I can't use the same hole for the Neos

bring ur old rd hanger and try. the best bring ur bike to double comfirm..

as for rd
any rd will do. but if u ask me, i will go for tiagra as most of my friends who love touring would recomend the same.

i had used claris, sora, tiagra, 105 and ultegra and all are good to go depends on how many speed u want!

try to look for trinx

welcome mate!

It should be item A-11 from this page. The item is readily available in Kimbell Jaya though.

Thx Desa,

Any source to point me to on how to loosened the headset? Is it in the manuals?

Damn the Dahons, nice as they are...they seem to give a lot of small assembly issues as well right out of the box...Mine came the back fenders giving squeaking sound when go over uneven tarmac.
Have to DIY to troubleshoot all these small irritating problems..and now this..Tight handle..What the..

Is noisy fenders a common issues?

sold off my dahon cause of many squeaking sound. mine is the folding part got sound. adjusted many time still same.

You know? I bought a 70K Peugeot and it still creaks here and there. What did you expect from a 2K BICYCLE? Folding one too!

It's just a matter of tightening some allen nuts and screws. If you can't handle that, I suggest you send it back to the shop to do it. Unless it is USJ Cycles, most will oblige. If you buy a right bike, a small portable bike tool can handle most tweaks. For me, I take off the whole mud guards, totally no squeak at all. I can't fathom how fenders can squeak? I mean there only 4 fasteners for each front and back. One main one fastens the fenders to the main body , one is at the fork and the other rear one is to the seat stays at the rear. Others are belongs to the wire contraption for the fenders.

As for the headset, you have to be sure it is the headset is too tight! Fold down the handle post and you will see a big hex nut inside. It is 12mm, if I am not mistaken. This tightens the headset and this is the one that holds the fork so it won't fall off the frame! At the neck of the handle post, you will see a 6mm allen nut and this grips the handle post to the fork's steerer's tube.

" LOOSEN THE 6MM A LITTLE AND THE HANDLE CAN TURN LEFT AND RIGHT. THEN USE THE 12MM HEX KEY AND LOOSEN THE BIG ALLEN NUT INSIDE THE HANDLE POST. JUST A LITTLE AND TURN THE HANDLEPOST AND SEE IF IT TURNS FREELY TO YOUR SATISFACTION. IF IT DOES, CHECK TO SEE IF IT HAS TOO MUCH CLEARANCE AS IF IT DOES, THE WHOLE HANDLEPOST IS LOOSE. ADJUST UNITL THE VERY LEAST SO THAT THE HANDLEPOST IS TIGHT AND DOES NOT HAVE ANY FREE PLAY BUT TURNS FREELY. ONCE OK, ADJUST BACK THE HANDLE BAR SO IT IS STRAIGHT AND TIGHTEN BACK THE 6MM ALLEN NUT. " voila!

If this doesn't help, that means the headset bearings are not well.

Thx Etigge for the in depth explanation.

I was having too much expectations initially..thus was a bit letdown from QC out of the box.
Mine came with back fender stuck on the back tires , have to manual twist the wire to push it back up, to free the wheels...can u believe it!!

Back fender squeaking loud ( the part where the fender is clamp by the 4 metal holder), and if u gently tap it and push the fender downwards...its will squeak.. and loud too...cant believe eh, so do i...Manage to adjust the fender by pushing the clamp for downward pressure, put a bit of oil..on the contact surface..to quiet it down. Still got the video if ur interested. I can only manage this due to my lack of knowledge on how to.

So, long story short..squeaks are normal on Dahon, is it?

Well..I will seriously look at your Handlepost guide, need time to digest, as it looks too technical to me on this one. Most likely i wouldn't dare to touch it.
Lastly, do Dahon handles set up to be tighter? Compared to other foldies. It could be this and im comparing to a wrong standard.

Sifu etigge,

Tried to assess the situation further, and its a tighter to the right hand side. When i turn the handle to the right...its gets stiffer along the way, and basically wont go beyond 90 degrees, unless applied a bit more force..
Over tightened headpost bearing?

Mine is a 2015 vitesse d8, is the headpost allen key size 12mm.?

Hahaha! You have to get used to which direction you are turning the screws or nut. Clockwise is tightening and anti clockwise is loosening. This doesn't apply to the bottom brackets and pedals though, the rest are !

Here's the picture of the mentioned nut. so, No 1....... loosen the 6mm screw first
No 2...... turn the 12mm nut anti clockwise a little, maybe 10 20 degrees will loosen the headset or maybe even less!

Check that the handlepost HAS NO FREEPLAY, means the handle can turn freely only and NO OTHER MOVEMENTS !! No rocking front and back especially. When you brake the front wheels, there should be no movement of the post to the front or back. NO FREEPLAY at all. Only turning.




PS/ OH yeah, remember to lock back the 6mm screw after adjusting!

Talking about 20H front hubs, I have just ordered one yesterday on Ebay. Not sure what the quality is like but should be ok.





I needed one so I can swap out the Biologic dynamo that is on the wheel that I recently bought from Rodalink. My Speed TR has the identical wheeel and I didn't want to be riding constantly with the dynamo dragging. Once I replace the dynamo hub with the one I ordered, I can then choose when to use which

I still can't believe how cheap the wheel was, so no problem spending more to replace the hub. Best of all, I'll have a matching original wheel.



Question to Sifu Etigge, not having laced a wheel before, how do you measure correct spoke length for the new hub?
Thanks!

Thx a lot sifu etigge... I'm gonna give a hard thinking and find courage to attempt it....as I fear might screw things up... Haha

There's a formula to calculate and you need to know the dimension of the hubs flange, hubs width and the type of lacing you are going to use. Darn complicated if you ask me, hahahaaa.


So, what I do is I will estimate and lace the 4 quadrants of the rim. And then lace another 4 to the other side. Check the length and then estimate how much to cut. Oh yeah, one more thing, the first 4 spoke has treads that go on and on and on so I can screw the nipples as far as needed. It's more like experimenting. Once you get the correct length, I will start adjusting all the spokes length together. Hard work actually but smaller rims are easier to lace.

Here's the website for wheel building.

Teflon tape will do

Sifus,

If i change the stock Dahon Rotolo tires ( 2.0 x 1.75) to Schwalbe Big Apple ..Can we still fit in the original fender as its much fatter.

Is the Big Apples much better than the rotolo in terms of handling and comfort? What are the negatives compared to Rotolo?

Appreciate the input. Thx.

My Link D8 squeak too, at the folding part. That's a real solution? not a joke right? I'm going to try that.

I was hoping not to have to cut by buying the correct length spokes. I'm not going to rush it, wait till the hub is here, there work it out. Thanks!
