Using a 100mm Front Hub on Dahon?
I have recently (last night!) acquired a late-model Boardwalk that I would like to modify somewhat for day-in, day-out, all-weather short-distance commuting. I think that this is a 2004 bike: it has the chromoly frame, straight fork and 6 spd. freewheel.
One proposed change is mounting on the frame an existing set of 20 in. (ISO 406) wheels that I built for another bike. These wheels use Shimano Nexus/Nexave roller brake hubs. These are standard hubs, the front hub having a OLN distance of 100mm. I note that being able to fully fold the bike is not a priority in my situation, and that I bought the bike for its other features (wheel size, frame dimensions, etc.).
I now realize (a little late ...) that the Dahon uses a proprietary fork / front hub combination with a rather narrow OLN distance. Any thoughts on how to proceed?
My first idea was to change fork. I would be happy to swap out the stock fork for a 20 in. chromoly fork, but I'm not sure if I will be able to find one with a 1 1/8 in. steerer. The 1 1/8 in. steerer is, of course, required for the stock headset and, more important, the Dahon handlepost. Is anyone aware of where to find such a fork? Gaerlan Custom Cycles has a couple of 20 in. forks, but both have 1 in. steerers.
The second idea involves cold setting the existing fork. But this would involve spreading the blades some 25mm, so it seems unrealistic and generally a bad idea.
Does anyone have any experience with this?
Of course, I could live with the front V-brake, but I have gotten quite used to the security and reliability of the roller brakes over the past couple of years, and I am prepared to pay a small weight and convenience price to have them on the Dahon.
