Riding in certain gear combinations can be noisy if you are NOT trimming the front derailleur when you change sprockets at the rear./quote]
cycling-obsession.comThe front derailleur can be shifted to 4 different positions as illustrated in the following chart below. I will be referring to the names of these positions in the article later when we are setting up the derailleur.
This is a good time to test if your derailleur is shifting to these 4 different positions. Fit your
bike into a workshop stand to make this process easier as you will need to rotate the cranks when shifting the front derailleur.
- Pressing the left brake lever all the way to right moves the front derailleur to the HIGH position which is the most outward position of the derailleur in relation to the frame. This setting is for riding the large chain ring and smaller rear sprockets.
- Pressing the small inner shift lever once, moves the front derailleur just slightly inward to the HIGH TRIM position. This position is for riding the large chain ring and the larger rear sprockets.
- Pressing the small inner shift lever again moves the front derailleur to the LOW position. This causes the chain to shift from the large chain ring to the small chain ring. This position is for riding the small chain chain ring and the smaller rear sprockets.
- Pressing the small inner shift one last time, moves the front derailleur just slightly inward to the LOW TRIM position. Now the derailleur is in it’s closest position to the frame. This position is for riding the small chain ring and the larger rear sprockets.
