I'm new to biking only doing it since the past 3 months. I don't use my front gears much since i'm pretty tall and lower gears means going at a very high cadence for little output. so wondering if i could remove the derailleur. Does this create any problem?

It can be done. Sometimes it's wise to not remove the derailer, though, but simply fix it in one position, as protection from the chain jumping off. – Daniel R Hicks Sep 2 '13 at 18:39

I would fix the derailleur on the gear you prefer (perhaps middle one, to get most of rear gear properly working) as the derailleur don't interfere to leg movement. Take in mind that in few months you can change your mind and start using front gears too.
Edit: To remove it you will have to unbar the chain, then open the screw (9mm wrench or 4mm alem depends on derailleur model) on other side of the derailleur. Then return the chain to place.

What would make this a good answer is an explanation of how to fix it in one gear. – Carey Gregory Sep 2 '13 at 22:43
If you remove the front derailleur, you're probably going to want a chain skip prevention device if you're planning to run a single ring in the front with a rear derailleur. Without something to prevent the chain from hopping off the front rings, you'll likely experience chain jumps frequnetly when shifting the rear gears or going over rough terrain. – Benzo Sep 4 '13 at 19:08

As others have said, sure, it can be removed, but let's look at the pros and cons.


  • A trivial weight reduction


  • You lose a whole range of gears intended for climbing
  • You lower the bike's resale value

You could reduce weight even more by simply losing a few grams of weight yourself. So unless you live in a place with no significant hills and never plan to sell the bike, it makes no sense to remove it. Just put it on the big chainring and leave it there. The presence of a derailleur costs you nothing.
