The Shiv TT has been optimized for a 1x drivetrain by moving the front derailleur mount to the back of the seat tube. A 1x set up can be run for the most aero setup. 

The front derailleur mount is removable/replaceable, S202600001. Complete bikes and modules will have have a front derailleur mount and bolts in the small parts box.  The mounting bolts are used to fill the holes when a FD hanger is not mounted.

The rear derailleur hanger is replaceable (S182600001).

The Shiv TT Disc is disc brake only, using the flat mount standard. Minimum brake rotor size is 140mm.
