Do others have prob's with smooth shifting in all gears on Dahons
I guess the problem seems to be that my speed 8 is good for 3-4 gears depending on adjustment, and there's considerable grinding in the other gears, though they function. Doesn't seem like the gear spacing or chain width is right.
Also-does your chain fall off the front? It's not that often, but usually after taking it out of the bag, so I jump on the pedal and nearly kill myself. Is this a chain tension thing (as I recall, somebody at LBS said that Dahons are often mistensioned).
Anybody have similar experiences/solutions?
Oh yes, I read about the chain popping off the chainwheel on Dahons for a long time. My own solution was 1. Purchasing the Boardwalk S1 with rear horozontal dropouts on the frame and 2. Having a three speed rear hub installed. Never had that experience on mine so far!
yes - this happened on my dahon 2005 speed8 too. I took it to lbs and they fixed it but a friend picked it up for me so I didn't get an explanation-so far it has been okay for about month. Another place to check on this complaint is on the Dahon website - there have been a cople of discussions on the forum there about this problem.
I get the chain on my Boardwalk6 to fall off when I shift into first at a fast rate. If I am slow and gentile it does not fall off. I've used a device called the N-stop on other bikes and I'm going to order it for the boardwalk. It is a delrin clamp with an adjustable stainless steel plate. You adjust the plate to within about 1/8 inch of the chain. It works. You will never have to deal with it again:
OH MY! I could have written the same thing. My bicycle shifted perfectly when new but now some gears grind and I suspect it's due the to the horizontal dropouts. The wheel has to be put perfectly inside the dropout or the gears will start grinding. I don't know how to fix mine yet but it makes me wish the bike had verticle droupouts.

Just as an update to these problems--I ditched the gripshift and just went with a bar end shifter in friction mode. I'm much happier now.

I unbolted the chainring and reversed it, so that it was tight against the chainring. I have not had a problem since.
