Convert your 2x crank into a 1x setup by replacing your bulky and non-aero front derailleur with this slim aero-optimised unit (improves airflow around the derailleur area to minimise drag and save you a few watts).

Also prevents those annoying accidental shifts to the small ring when you least want them!
