This a beautiful Cannondale CAADX Ultegra cyclocross / gravel / commute disc road bike with many upgrades and custom parts in gloss black color. The paint color is not just plain black, it has slight metallic sparkle to it. It started out as a CAAD X 105 disk but I have upgraded the components to full Ultegra, upgraded the crankset to Cannondale SI road cranks, upgraded the wheels to Fulcrum Racing, upgraded the brakes to TRP Spyre, upgrade the seatpost, stem and handlebars to Cannondale C1 or C2. I have also added a custom inline top brake levers in addition to the regular shifter brakes. It will come with extras like rear rack, front and rear fenders, water bottle cage, and a bell.
 
The bike was purchased new at the end of 2015. I use it only for commute for a short period of time. It has very low miles, around 600 miles. It is in close to new condition and has not been dropped or crashed. This is one of the best bike I've owned and a truly ultimate commute bike.

The frame size is 56 (560 mm effective top tube). It should fit someone around 5'10" - 6'1". Cannondale is a high end bicycle manufacturer like Pinarello, Cervelo, Bianchi, Time, Wilier, BMC, Scott, Felt, Orbea, Focus, Ridley, BH, Trek, Specialized, Giant and even Raleigh, Kona, Marin, Gary Fisher, Fuji, Jamis, GT, K2, Redline, Norco, Novara, Santa Cruz, Ellsworth, Intense, Klein, Salsa, Banshee, Brodie, Niner, Merckx.

I am asking $1275 or best offer (MSRP NEW on an Ultegra CAADX is $2170).
