2013 Cannondale Trail SL 2

This bike was bought brand new this summer, but I'm tossing around the idea of upgrading. It has less than 100 miles on it and might as well still be brand new. It is all stock with the exception of a lizardskin chainstay protector.

The only real wear on the bike is that the crank arm paint is a getting worn off from my shoes and some minor scuffs from typical use and being on the bike rack. The tires even still have some of the little knobs on the sides. Some of the specs for the bike can be found here: http://www.evanscycles.com/products/cannondale/trail-sl-2-2013-mountain-bike-ec042885#

But at a glance it has:
-Large (19") Frame
-26" Wheels
-Rockshox Recon Silver 100mm fork
-Sram X5 front and rear derailleurs
-3x10 drivetrain
-Avid Elixir 1 Hydraulic brakes, 160mm front and rear

The bike was brand new for $1300 a couple of months ago, so I'd like to get $1100 for it, but I'm open to offers. May potentially trade for a FS bike of comparable value.
