I got a Dahon Speed 7 at a NJ flea market for only $35 - but it was left out in the rain for few years.

I want to grease the wheel nubs - I cleaned the ball bearings - but front and back both have rubber/plastic dust caps - can I buy just these - can I get metal dust caps (or new matching plastic ones) some place online?














...Also the seat post sleeve rusted and needs to be sanded or replaced - as well as the shifter cable. I am also putting on a new seat and new tires.

I'm not sure about the front, but your rear looks a lot like a Shimano RM30 or RM40 or similar hub. You could probably either buy parts, or find a donor hub.

A lot of the rest appears to be just replacing cables, housings, and etc.

[QUOTE=NYCDahon;20185515]CliffordK thanks for the advice on the rear. The Dahon front hub has these rubber/plastic dust caps - can I get substitute flat metal dust caps of some type.

Thanks! I'll check them out - but I have to admit - I tend to order online.

Is there some way to measure this and replace with metal.

OK - I got everything back right but now I need to put a chain on it - any advice? I assume just start with it at the biggest gear set - but would love to know what length Dahon Speed 7 shipped with.

Any pro mechanics out there?

Generic chains usually come extra long and need to be cut. Just lay it side by side to the old chain to get the right number of links.
This is assuming the old chain HAD the right number of links. If unsure; Parktools site has good tutorials on measuring.

My problem is that I don't have the original chain.

Put the rubber seals back in

the metal disk ones, don't seal as well and the grease tends to run out since the gap is at the outer circumference instead of in the middle.


for chain length, wrap the new chain around the big cog and big(only) sproket, Without running through the derailer
find where the shortest possible link connection is, then add 2 full links to find the length.
(for a 3 sproket drive, 1 full link)
(for a 1x drive, 2 full links)
('full link' not to be confused with 'half link')
