This is a brand new build starting with a new Airborne CX Delta aluminum frame. The frame was built as a cyclocross bike but can be used for gravel riding. Size of the frame is 55cm. Many new parts were used throughout. The list of new parts include the following -Shimano 105 shifters - Shimano 105 front derailleur - Bar tape - 80mm stem -BB7 Mechanical brake calipers and rotors - cables and housing The wheelset has very low miles with less than 200 miles.

The remainder of the build includes the following -Winwood Carbon Fork -FSA Gossamer 46/36 crankset -Shimano 105 rear derailleur -11-32 cassette -Thomson Elite seatpost -WTB saddle The bike looks and rides great!
