good to hear Bando that Dahon came through with such an "old" part to get your bike rollin again.
this thread is from 2006 .... a little old in the teeth otherwise.... but if somebody needs a delrin block to fix the split one he has, just email me and i will mail one to you ....
There are not many cases where this little bugger gives any problems ...with a couple million bikes out there with that system I did mail out 6 pieces last year ....
