Can you put any derailleur on a road bike?
This means that you can use an 8 -or 9-speed mountain bike derailleur with road shifters or vice versa. The only exception is pre-1997 9-speed Dura-Ace gearing, which won’t play nicely with anything because it uses a totally different cable pull ratio.
Is it hard to install a derailleur?
It’s relatively easy, and if you haven’t done it before, you’ll learn the procedure of tuning a rear derailleur from scratch, which can be invaluable out on the trail. Are you planning on installing a new cable? It’s not required, but this would be the time to do it. If so, you’ll need cable cutters.
Do you need a front derailleur?

How do you adjust a derailleur? Hop off your bike and do this: Shift your chain into the biggest chainring and smallest cog, then loosen the cable clamp bolt (where the cable attaches to the derailleur).

How do you adjust rear derailleur?
Step 1: Make sure the rear derailleur is shifted all the way down into the smallest cog. Step 2: Turn your barrel adjuster all the way tight so that you have room to adjust it later. Step 3: Adjust the high limit by rotating the screw on your derailleur marked “H” so that it lines up with that smallest cog.
How does a bicycle derailleur work?
A bike’s derailleur, also spelled derailer, makes it possible for a bike to shift gears. This device pushes a chain from one cog to another. A derailleur may look like a fancy piece of equipment, but it’s really quite simple in design, and most of the force behind its action is provided by the rider.
