The road oriented bike shop in town (which was pretty awful) closed a month or two ago. The other shop in town, which is really good is closed for the month (they do that every February). I tried a couple dealers on the internet who claimed to have them in stock on their web pages, and none actually have them. The estimate for a date to get them in stock is mid April. I've tried Dahon directly, they said to contact their dealers.
I'm working on the same ASME competition I did last year. I'm building a new bike, and thus need a new derailer. Last year we ended up taking the one from my folding bike and modifying it. That never got replaced so that isn't an option this year. It's a simple little stamped metal part. Retail is only ~$20. This really shouldn't be hard.
If anybody out there has one (or three) version 1 or 2, that they would like to sell, or if you actually know where to find one, please let me know.
It looks like this (nice people, they just didn't have one):
For those who are more curious, the project is here:
I'm going to post this in "Bicycle mechanics" as well. If a mod feels the cross posting is inappropriate feel free to let me know and/or merge them. I'm doing that is in the past I have gotten very different responses between sub forums.
