9 Speed Upgrade Question

Hi Everyone, I recently installed an STX crank on my mountain bike, and I'd like to convert from the
7 speed freewheel to a 9 speed setup (probably the LX kit). Do I need to get 9 speed chain rings for
the STX crank, or is it ok like it is? It shifts just fine in front now, but I don't know how the
narrower chain will impact things.

Any helpful advice would be greatly appreciated.

Thanks, Steve.

 

It'll be fine. I just got back from a ride with my 7 year old STX crank with original chainrings on
a 9 speed setup.

My wife's bike is currently set up with a 46-36-26 Shimano RSX crankset - nominally "seven"
speed/steel rings - with Shimano 105 nine speed STI/cassette/chain - with no problems
