Dahon Visc D18 Tour Question

  1. Is the frame drilled for caliper brakes?
  2. What kind of shifter is on the bike?
I would need to convert to drop bar...so I like to know if I need to buy different shifters.

I have small hands so I use special levers that work with my small hands...but it's not compatible with V-brakes.

Can the shifter on the Visc work on a drop bar?

This bike uses a Shimano derailleur with a flatbar shifter. You can use a Shimano or MicroSHIFT 9-speed bar-end on dropbars.

Tektro makes a small-hands road brake lever that will work with v-brakes, and even better with mini v-brakes.

Sure, if you feel confident that you can grind some material away from the clamp area. Getcher Dremel out and get to work!

The Visc D18 Tour is a 25.4mm Handlebar setup. However, the attachment system has 2 clamp brackets that are set approximately 9 cm apart on the outside. This means that whatever handlebar is used needs to have 25.4 over a relatively long length for handlebars.

Basically any 25.4 handlebar can work if they are shimmed to that general diameter at 3.5-4.5 cm each side of center.

It might be easier to mount Handlebar Grips to the outside of the stock units to give yourself variable grip capability. There are many of these on the market. None, that I know of though, which transform a flat bar into a drop bar. You can get a bullhorn effect though.

The Mu D10 Tour has a "center mount" quick clamp that can use any 25.4cm Handlebar dimension. I found that Dimension Trekking handlebar is very nice on most Dahons including the Mu D10.

The Visc D18 Disc however is a 31.8mm Handlebar setup so keep that in mind if you go that direction.

I have all of these bikes and the handlebars at my shop nomadic.net in Boulder, CO. Not all the handlebars are listed but I will get to that soon.

Visc D18 Tour Handlebar (I need 10 posts before I can post a picture). If interested in a full set up or just more info you can also contact me via my web which is nomadic (dot) net.

Bike can use caliper brakes but...

You can use Caliper brakes but you will need different braking levers in my experience. Brake levers made for V-Brakes do not have the leverage you want for caliper brakes. Basically V-Brakes themselves have alot of leverage, while caliper brakes need the leverage in the brake levers. There are some "helper" systems that can bridge this but still.

Using Micro-Shift shifters are no problem on any handlebar in my experience. Not sold on "drop bars" but mainly because they have to pack in a bit more space.

Visc is an awesome bike no matter. Drop Bars will work very quickly with the Anniverary Replica bike if you want to consider that one. All good bikes.

Width on the Visc D18 Tour handlebar attachment

This is the view of the top of the Visc D18 Tour Handlebar.
It is not automatic putting drop bars onto this setup. I think it can be done but its quite a job testing. Happy to if we get more into the subject somehow.

Perhaps stated photo size restrictions are not enforced. I can see the dropbars above being quite a bit bigger than this photo here, but anyway.... Can post bigger for sure

(thats the Visc SL in the suitcase in the background - should have removed the newspaper but was not watching the background then)
