Will 2×11-speed front derailleur work on 2×9 system?

5 min read

Asked by: Cherie Santiago

The short answer is yes, it should work.

Are front derailleurs interchangeable?

In addition, front derailleurs are made for either 7, 8, 9 or 10-speed chains, but they can often be used interchangeably. If you are using a different chain than your derailleur was made to work with, the degree of adjustment you can expect will be lower than with a matched set.

Will a 7 speed front derailleur work with 9 speed?

Yes. A front derailleur marketed as for a 9 speed system will work normally with your 7 speed set up.

Do front and rear derailleurs have to match?

The shifters and derailleurs need to match. Front: Sram and Shimano work with eachother on the front derailleur. Rear: Sram and Shimano do NOT work with eachother on the rear. They have different pull ratios and you need to match brands here.

Will an 11 speed front derailleur work with 10 speed?

And your intuition is correct that a Shimano 11-speed shifter will not work well with a 10-speed front derailleur because the 11-speed shifter is designed to actuate the longer lever arm of Shimano 11-speed front derailleurs.

Does speed matter for front derailleur?

The number of rear speeds (the 9 in 2×9) marked for a front derailleur isn’t too important, but the cage of the derailleur may be thinner for higher number of rear speeds (so if your chain isn’t designed for high enough speeds, you may have some rubbing on the cage, especially if you don’t adjust it properly) — as

Will a 7 speed front derailleur work with 8 speed?

8 speed shifter and cassette, 7 speed derailleur? You’ll be fine. There’s no “probably” about it. 6-, 7- and 8-speed gear is all cross-compatible in terms of chain width.

Can you use a 10 speed front derailleur with 9 speed?

Because the 9 speed cassettes width is the same as the 10 speed,and the width of the chain coupled with the distance between the front mech plates has been designed to work together,you wont experience excess rubbing in the extremes.

Can you mix front and rear derailleur?

The only two ways the front derailer and rear derailer must be compatible are 1) they must be assuming the same chain width (or at least reasonably close), and 2) they must combine to produce a reasonable chainline (more a function of the crankset than the front derailer).

Will a 9 speed front derailleur work with 8 speed?

It will work with an 8 cog cassette and 8 speed chain, but it will rub sooner when cross chaining.

How do you know if a derailleur will fit my bike?

Check Your Chainring Size. A big difference in chainring sizes can also determine the length of the cage you need your derailleur to come with. If your bike has a cassette with like 11-20 gear ratio, then you need a derailleur with a shorter cage. Most mountain bikes come with bigger cassettes.

Can I use a 11 speed front derailleur?

Front derailleurs are friction shifting, not indexed, so they are largely compatible with other brands. Yes, you can use a FD from an 11-speed groupset – it doesn’t care much how many gears you have at the back.

Is the front derailleur dead?

SRAM are announcing the end of the front derailleur in mountain biking. The 1x drivetrains on offer from several manufacturers coupled with the range of gears on offer from an 11 speed cassette have rendered the front mech obsolete.

Are Shimano 10 and 11 speed compatibility?

A 10-speed Shimano or SRAM cassette can still be fitted to an 11-speed body, but a spacer will be required to make up for the difference in width. There is another, more subtle, incompatibility that affects different brands of hubs and wheels, but it will only have an impact on those riders using multiple wheelsets.

Are SRAM and Shimano front derailleurs compatible?

Yes, you can mix Shimano and SRAM front derailleurs and shifters. It’s the rear derailleur that is not cross compatible, with the exception that SRAM has made ‘Attack’ shifters that will work with the Shimano rear derailleurs.

Are all derailleurs the same?

No, bike derailleurs are not universal. A derailleur that works with one bike may not work with another bike based on factors such as the cage length. Check the difference between the smallest and largest cogs and also the chainring size to determine the derailleur compatibility.

How do you replace a front derailleur?

Quote from video: The front derailleur down to the smallest chainring up front. So shift it down next you want to remove the cable. That's where use the five millimeter allen wrench.

Can I use a MTB front derailleur on a road bike?

Yes, if the ring spacing is the same, but the front shifter pull ratios are different, than the FD themselves must be different as well (as you say “making up the difference”), just like you find with SRAM vs shimano mtb RD’s and rear shifters.

Will a 9 speed front derailleur work with 8 speed?

It will work with an 8 cog cassette and 8 speed chain, but it will rub sooner when cross chaining.

Why do mountain bikes have no front derailleur?

Mountain bikes no longer have a front derailleur because of the invention of the wide range rear cassette, meaning you can have the same range of gears with fewer parts, which saves weight, and keeps things simpler. Also making the bike build look cleaner.
