Changing the grip in my Dahon.

Hi!..
I want to change the grip for my Dahon Mu-P24 (2009 model), as they are broken.
I would like to buy the Biologic Arx Grips.

My issue is when I try to check the right grip.
The grip part to change the gears is 5 cm / 2 inches. The other (outer) part is 6 cm / 2.3 inches


So far from what I've seen, the version for twist shifters is 10 cm / 3.9 inches (right) and 13 cm / 5.1 inches (left)

I'm attaching a picture so you can see what I'm talking about.

1 - Will the long/short Biologic Arx Grips fit?
2 - How can I change the internal grip for the gears part? is there anything like that for sale?

Thanks!..

Get the normal length Ergons and cut them to fit. A much nicer grip I think.

Some Ergons also come with bar ends that I found to be very useful in providing an alternative hand position.

I'm planning on setting a DD on my NWT and plan to shave down some Ergons to fit. The stock setup is narrow in diameter as compared to the DD shifter. I'm curious as to whether there are other options.

Some Ergon grips have a SRAM/Gripshift version.

its a little difficult, as the shifter part of the grip is rather thick, most grips are thinner and leave a not so great stepdown in diameter...
best if you find a regular grip with the right diameter and than cut it off .... the Ergons or Biologic ARX are too thin ....
unless you find a way to make the outside of the shifter smaller in diameter ....OR cut some stuff off .... than it would work fine

That's a weirdly shaped grip if ever I saw one.

The diameter of the shifter end is about 40mm. The diameter of an Ergon grip, if you will cut to the correct length (or get a precut microshift version) will be about 35mm so this is close.

Another option you have is to switch to separate left/right DD twist shifters which have a more standard size. Dahon shipped later model Mu P24 with this kind of shifters (3 position on the left, 8 positions on the right). The right side is a standard SRAM 1:1 8 speed twist shifter, the left side is a special model that you can try get from Dahon. The DD integrated shifter is a pain IMO.
