read up... from the post i quoted previously... "So which is it? Seems the desire has changed from your original question about putting a 9 speed freewheel on your bike of unknown model and speeds on the rear. And now you seem to just be wanting a new wheelset for your bike of unknown model and number of speeds on the rear.


Wanting more speeds on the rear seems to suggest you didn't have the gear ratios you needed. Wanting a new wheelset seems to suggest your wheels are worn out. Which generally isn't likely. Though there can be many valid reasons, that you haven't stated.

So knowing more about why you think you want to change either will get you better suggestions."

that's how i determined that you are confused and/or uninformed.

and here's what you called "Bluntly"..

"Do not waste cash on that 9 sp. freewheel. There is no real advantage to adding one or two more cog, unless you're trying to increase range of gearing, and that leads to needing a 9 sp., chain, that is longer, a 9 speed shifter, and a different derailleur capable of taking up the extra slack.

Direct Disadvantage? you still have an over-stressed hub design that loves to bend axles. AND the 9sp. freewheels i've seen are from a company called Falcon, and should be AVOIDED, Period.

Advantage? bragging fodder....and your 7-8-9(!)sp. Derailleur will still work on a 9 speed setup. unless you go for a far wider gear range... 10 sp. is where the Pull Ratios begin to change significantly.

before you ask,,, a seven or 8 speed shifter won't work to just shift 7 speeds on a 9 speed freewheel or cassette, since the distance from one cog to another changes with gear counts.

best plan? get an 8-9-10 sp. Freehub/Cassette wheel assy, a 10 sp. Der. and Shifter, then mount it all up at once.

your maximum TOTAL tooth change from small/small, to large/large cogs will need to be considered, as will your riding area terrain."
