Remote Aero Bar / TT Shifter

Synchronized Shift only

If you don't use a front derailleur on your time trial bike feel free to ignore this, but for those of you that do - these shifters can only be used with Synchronized Shift. They only have one button each, so you generally set one up to shift the RD to an easier gear and the other to shift to a harder gear.

Using Synchro Shift would make the bike shift the front derailleur automatically, so not being able to shift the FD using a button or shifter is no problem.
