Which Front Derailleur is Right for my Bike?

Oddly, a front derailleur can be more difficult to install than a rear derailleur. A derailleur moves the chain from one gear to another. The one in the front is in charge of the big cogs. Moving the chain on the big chain rings takes more force and finesse.

What kinds of Questions should I ask Before Choosing a Front Derailleur?

  1. Is there room for a front derailleur? Some dual suspension frames require “E-type front derailleurs” which wedge themselves between the bottom bracket and BB shell of the frame.
  2. Where is cable coming from? The pull of the cable will come from the top or bottom. Some newer derailleurs can be pulled from either direction
  3. If the front derailleur is attached to the seat tube, what is the width of the seat tube? Standards include: 28.6, 31.8, or 34.9mm
  4. Front derailleur cages are designed for specific widths of chain. How many cogs are in the rear cassette? Rear clusters come in 5, 6, 7, 8, 9, 10, or 11 speeds.
  5. The curvature of the front derailleur cage is supposed to match the maximum amount of teeth that the derailleur is designed for. Road bikes typically have bigger chain rings, thus mountain and roadie front derailleurs are often not interchangeable.
  6. What is the throw of the front derailleur? Cranks come with 1, 2, or 3 chain rings.
  7. Depending on the cyclist, it can be important as to what brand and variation of the other components. Some people just want one that works, other people prefer a higher quality one that may look better or be lighter.
  8. If you have more than one derailleur that could fit, which one weighs less?
  9. Is it a racing road bicycle or mountain/hybrid bike? The jump from one chainring to another is different various styles of bikes. How great the jump in teeth sizes will determine the depth of the front derailleur cage.
  10. Front derailleurs can be clamped from above or below. Sometimes, it doesn’t make a difference. Other times, the shape of the frame will force you to pick a very specific derailleur.
  11. Some bikes have a welded attachment on the bike for front derailleurs. These are called “braze-on” front derailleurs.

Now that we Know there is a lot to Choose From. Here is a list:

*It is important to know that the mechanic at your local bike shop can often help you find the right front derailleur. If you show him or her the bike, things get a lot easier.
