actually bro,
its the frame design that u cant fit those rear caliper. im using tern verge and ur fnhon frame just like mine. u cant fit ur caliper like that, instead try moded it like mine behind the seat stay



oh ya,
my caliper is sram red, and after comparing with 105 caliper, red are much shorter few mm than 105. still can be used with those method front and rear.. happy trying

Totally agree with u. Super leceh... I tot building by the numbers is safest way

Just duwan fork to break. Aluminium stuff is new to me, if its that brittle and no flex... Sked abit

Have you check your fork if it is aluminum or steel? Just because the frame is aluminum, doesn't mean the fork is. Just make sure and see. Check the welded joints and see if you see paint cracks? The first thing to crack is the paint work. If there are none, it should be OK.

I build/mod with numbers and measurements. Sure can wan.

Safety 1st. 2~3 hundreds to replace the fork consider tuition fee lor. Redo your search, learn much detail. I will allow patch job elsewhere but not on structural integrity and braking power.

Before we jump to a conclusion, Use magnet to check if your fork is ferrous or non-ferrous. Refrigerator magnet is good enough.

Aluminium forks cannot be cold set. You'll need to re-lace the wheel to a 74mm hub....but looks like your rim is either 32h or 36h, which I doubt you'd find a hub to match.
No worth risking your face hitting the road at speed....

Now looking for a suitable fork with 100mm opening, which i noticed is found alot with disc-brake config... Is the nut mount the same between a disc-brake wheel and a normal one?... this is the better option for me. Worse case is find new wheelset and new fork to use back 74mm

i had done few modification extend the wide of fork or frame before.
previous setup i had done with my dahon vybe fork with novatech mtb hub, my trinx ka1606 (fork and rear) and also my dahon classic (rear widen)..

the tools are most likely DIY tools and looks similar like this



lucky here my friend got special tools to do it.until now it works without any problem.unless u had money, u can buy another fork and that is another story

if u cant find normal folding bike fork, u can try minivelo fork for 100mm open. the stearer tube a bit longer, but u can cut later. i still keep my doppelganger fork for spare. but that fork are heavy and weight around 1kg+

After expending rear hub spacing, adjust for symmetry is a good practice.

Sheldon is a good reliable source of bicycle information for me. Here's his take on frame and fork spacing.

Hi all sifus,

I managed to find this fork with the following specifications. There are a few questions, hopefully can get some answers here. The fork opening is 100mm and for 406 wheels. In the diagram and description - the steertube is 180mm, if bring to LBS, are they able to cut this excess of 40mm or its another thing i need to DIY?


Another concern is the steertube is non-threaded, and the same link suggest to have some sort of adapter with the pic below. Is this a doable thing or need to find one with original threads? My original fork has threads in them.


Include is the original link... whomever can read chinese. Many thanks again all sifus..!

Are you familiar with the difference between threaded and unthreaded tube? Meaning how they are used? Sheldon's site has very detailed information. Much better than I can ever elaborate.
Ingeneral, threaded and non-threaded are incompatible in many ways and you must not assume there are miracle adaptors that will make them fit magically.
Threaded don't use the star nut you asked about.
According to your attached drawing, the fork opening is 74mm.

*PS, you bothered to check what your fork material yet?

you can still sell your current wheelset ler.. wont rugi much..top up a bit for a new wheelset..then get a replacement fork. no need to pening2..

just my 2 cent.

bingo, sell current wheelset and dont change the fork.plus minus is the same i think.

this wheelset wont cost much i think.

thats my 2cent 😉

oh ya, those starmut needed to tighten ur handlepost with fork. if im not mistaken fnhon (just like dahon) use the threadless fork.

im using carbon fork fork minivelo with longer stearer tube and cut it to fit my tern..no problemo.

Hi all folding bike guru, been silent reader here for couple of months, and did some searching and reading on foldies.

Planing to buy a folding mainly due to the size when transport with sedan, and cycling won't be hardcore.

I am looking between Dahon ios D9, and Tern verge D9 since price don't varied much. Any take on the two model?

Another wild idea is build one (been reading http://handsonbike.blogspot.my), seem possible.

Didn't want to reply due to to much contrasting comments over mine but , heck! can't resist

Since your plans are quite simple, why don't you have a look a Crius which Billy Bike Shop has a unit which he can't get rid off. The frame is similar to Tern Verge aka Dahon Vector and it is assembled by Lite Pro. No of speed is 9, I think, and it is light and selling for about 2K plus.

The comparison you requested is way too different. One is a 24 inch folding bike while the other is a 22 inch bike. So, no comparison except one folds smaller

Haha, thanks for the advice, where is Billy Bike Shop BTW?

Taiping.. but he has online shop as well..can google or find at BBS..i bought a few items from him through online.

Honestly....folding bikes look terrible! but....i have lived in so many super busy places that maaaany times i wished i had one!

Nobody will know what bike you need other than yourselves. So just buy one at the price that you don't mind giving away and ride the hell out of it. The next bike will come closer to your dream bike.
Get the 406, keep changing and upgrade till it becomes your dream bike, then get a 451 and repeat the process, after which you start doing it on a 16", after which Brompton, … then you get a 700c Road Bike, and later it's variants such as TT bike AeroBike，touring， MTB 26", 27.5", 29" wich it's variants xc, downhill,… Hybrid… foldable 700c, minivelo 306, 359, 406.
Then you can start playing Triathlon, Ironman, cyclocrossmetc etc

But of course you can quit halfway and be a cycle-for-more-food AKA Kaki ayuh-makan-kayuh, like me which it doesn't matters as long as it's a bicycle

The ideal number of bikes to own is n+1.
n being the number of bike you currently own. Just like golf set
