Niner Air 9 Carbon Geared Kit $60.00
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.
