The ol' switcheroo.

If you'd like to add some more cogs to your Niner Air 9 Carbon, there's no easier way then this Geared Kit. It includes the performance Shift Kit -- a sealed guide tube with ferrule and the bottom-bracket located nylon guide -- and titanium guards for the bottom bracket shell and chainstay to protect from chain slap. An aluminum hanger completes the pack to get you shifting gears.

The derailleur hanger broke on my 3rd ride. I was riding on moderately uphill xc terrain. The hanger snapped and sent my derailleur into my spokes. It ended up chipping my frame and chewing into my spokes. I hope this was just a defective hanger and not representative of the product in general.
