How To Choose The Right Derailleur?

These are a few factors you need to consider before buying the right derailleur for your bike.

  1. Durability: Whether you’re looking for a new rear/front derailleur or a replacement, longevity is one of the first factors that you need to be particular about. Aluminum or steel may be more long-lasting than plastic ones (although, it also depends on the brand and quality). The more durable it is, the more satisfied and comfortable you would be; thus, try to choose your product after ensuring its durability and performance.
  1. Gear ratio: Before purchasing a new bike derailleur, assess the number of gears that your setup can manage. If you are just replacing a broken/old one, you need to count the cogs in your cassette and ensure that the speed of the bike derailleur matches the speed of the shifter. When the right gear ratio isn’t ensured, you will end up breaking the rear/front derailleur.
  1. Cage length: The cage length is the distance between the upper and lower pulleys of a rear/front derailleur. Deciding on the best derailleur according to the cage length determines the speed, range, and shifting of your bike. Cage lengths are of three categories — short (SS), medium (GS), and long (SGS). Usually, mountain and trail bikes have high gear ratios, and thus long/medium cage derailleurs are preferred. Short cage bike derailleurs are good options for road bikes with double chainsets.
  1. Mode of gear shift: Several products offer mechanical and electronic shifting. If you opt for electronic shifting, you need to choose a front derailleur with compatible gears and brake. The major difference between the modes is shifting movements. Electronic bike derailleurs offer more precise shifting than mechanical ones.
  1. Tooth capacity: Tooth capacity refers to the difference between the smallest and largest cogs, which is then subtracted from the difference between the smallest and largest chainrings at the front. This represents the capacity of the derailleur with regards to the chain movement or slack. After assessing this, you need to purchase a rear/front derailleur that would fit your setup.
  1. Clutch: Clutch ensures precise shifting and chain movement even on bumps and muddy lands. Thus, rear/front derailleurs with a clutch would be best suited for trail and mountain bikes rather than road bikes. You need to make a choice according to your needs and current setup!
  1. Weight: The derailleur that you opt for must weigh in a way that is compatible with your bike/bicycle’s weight. Usually, mountain bike riders can go for a lower weighted derailleur for better control and command on rough terrain. In contrast, road bikers can have a slightly increased weighted derailleur. Lightweight bike derailleurs are the best option for trail riders and racers.

Sam Lawrence, a cycling fanatic, reviewer of e-bikes, and professional bike mechanic, says, “The derailleur should be compatible with your bike in terms of weight and speed. It should also be easy to install and adjust. Many bike derailleurs are very complex to set up and may leave you frustrated. Check their mechanism, technology used, and other equipped features for an easy and simplified installation, adjustment, and removal.”

Frequently Asked Questions

1. Are all derailleurs the same?

No, not all derailleurs may fit all bikes alike. Certain derailleurs are specific only to certain bike models and cassette ranges. Some ten-speed bike derailleurs with 11-42T cassette configurations may be compatible with a wide range of bikes

2. How long does a rear derailleur last?

Most reputed and well-made rear bike derailleurs are sturdy enough to last for many years at a stretch, provided they are maintained properly.

3. How do I know if my rear derailleur is worn out?

If any component of the rear derailleur, such as the pivot joint, springs, hanger, or chain guide wheels is sloppy, loose, worn, or bent, it’s time to replace your current derailleur with a new one.

4. How do I stop my rear derailleur from skipping?

That solution depends on what’s causing the derailleur to skip or jump. The most common reasons include a bent hanger that needs to be straightened, or stretched out gear-changing cables that need the tension to be tweaked.

The Bottom Line

Installing derailleurs can make your bicycle riding experience safe and secure. However, finding the best derailleurs can be a draining task since there are plenty of options available in the market. So, pick one that is made from steel and is long-lasting. Top picks include the Shimano Altus Mountain Bike Rear Derailleur, suitable for city and mountain sports, and the Sram GX Eagle Rear Derailleur, offering precise gear shifts and 12-speed variations. Before purchasing, consider factors like longevity, gear ratio, cage length, and weight. Derailleurs vary in size and structure depending on whether you have a mainstream bicycle or a geared bicycle.
