Folding Bikes - Cassette for Dahon Speed
Bikeforums.net is a forum about nothing but bikes.

What cassette would you recommend for a Dahon Speed, circa 2007. The stock cassette just doesn't do the trick on hills for me anymore as I'm touring on this bike now and carrying camping gear.
Are you asking for gearing recommendations or which cassette fits that bike? Either way I think we will need a bit more information.
I am guessing it is gearing recommendations you want, what is on the bike right now? (How many teeth ie 12-28 etc)
It's a seven-speed, and the gear ratio is 14-28. I'd like to know which cassette would fit this bike. I was looking at this one (http://www.chainreactioncycles.com/Models.aspx?ModelID=6387).

Sounds like a D7, which probably has a freewheel sprocket set. The P8/9 used a freehub and cassette. If the bike is a D7, it most likely also has the Neos derailleur. It's difficult to upgrade the Neos, so it could determine the largest sprocket you can use. If it's a freewheel, that cassette will not work.
Before making any purchases find out what what the existing system is, as it tends to shift from year to year with Dahons. Thor(http://www.thorusa.com/) is an excellent resource, and hangs out here as well.

+1 to what Clownbike said. You need to determine if it is a cassette or a freewheel. I assumed cassette 'cause that is what you said. If it is a freewheel you will probably be limited to a 12T or 13T as the highest gear.
I know the Neos will handle a 30T as I have one on my bike. Lower gearing is easy though, just go to a smaller chainring up front.
