I'm thinking about doing a 2x10 setup sometime in the near future. Would this require buying a entirely new crank and cassette, or can I just take a third ring off my crank set and add more gears to my cassette?

*forgot to add that I have a 2010 Gary Fisher Advance.

James, you'll need the following: 10 speed shifters, 10 speed cassette, 10 speed chain, 10 speed rear derailleur. I would just stick to 9 speed until you buy a brand new bike equipped with 10-speed.

You cannot add another gear to your evenly spaced 9 speed cassette.

Thanks for the info guys! Didn't think it'll turn out to be that complicated. I guess I'll have to do more reading on my part. I like the way my bike is currently set up even though it is stock, but I almost never use the biggest ring on my crank set. I might as well keep riding till eventually the components wear out, then do a major components upgrade.

If you've thought about it at all you should. Adding a bash guard is safer for your legs and way more convenient on log-overs. My new bike had a 2x10 or 3x10 option on the build kit. I specifically went 3x10 to replace the big ring with a (real)bash guard. The available 2x10 specific bash guards are a joke IMO.

I think 2x9 is the better route for you. Just get different sized front rings and let go.

I have a 2x10, really one gear difference in the rear won't change much, save your money for other stuff.
Thanks Paulrb02, now i'm really thinking about just doing a 2x9 and taking out the larger ring for a bash guard. It's probably the most cost effective way to lose a little bit of weight and get rid of the large outter ring that i don't use. It just makes sense and i don't have to spend a lot. I appreciate all the info guys, the biking community in this forum is great, compared to car forums i've been in the past, you guys rock!.
