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.
Can I use a different front derailleur?
That's because, as with rear derailleurs, they may use different cable-pull ratios, which shift the derailleur cage a different distance when you operate the shifter lever. They are also speed-specific, so you can't use a front derailleur designed for an 11-speed drivetrain with a 10-speed drivetrain, for example.
Do I need a specific front derailleur?
Are Front Derailleurs Necessary? These days front derailleurs are essentially not necessary, on mountain bikes at least. Now even high-end road bikes are starting to lose their front derailleurs. With a larger rear cassette, it's possible to get the same number of gears without the need for a front derailleur.
Can you mix and match front derailleur?
Unless something is wrong with the old front derailleur, I'd keep it. Just clean it, lube it, etc. Yes, you can mix and match.
Can I use any derailleur for my bike?
A derailleur for your mountain bike should match the specifications on the original derailleur. That is, while it doesn't need to be the same model of derailleur, it does need to be the same brand, in almost every case. It also needs to match the number of gears, or have more intended.
36 related questions foundAre all derailleurs compatible?
As a general rule of thumb, it's best not to mix and match drivetrain components from different brands. While things such as cranks, chains and cassettes are mostly inter-compatible between brands, generally speaking, shifters and derailleurs aren't.
Does derailleur need to match cassette?
The rear derailleur must be matched to the size of the largest rear sprocket. This capacity, which is expressed in terms of teeth, accounts for both the difference in size between both chainrings (e.g. 14T for a 53/39T crankset) and the largest and smallest sprockets on the bike (e.g. 17T for an 11-28T cassette).
Can I use MTB front derailleur on road bike?
MTB vs road FD
Shimano road and MTB FDs have different cable pull ratio – that is the amount of FD movement for each mm of cable movement. This means that MTB FDs might not work well with indexed road shifters and vice versa.
Are all Shimano cassettes compatible?
SRAM and Shimano cassettes, on either road or mountain bike, are interchangeable with each other as the spacing is the same between the sprockets.
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.
Can I just remove my front derailleur?
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. Then you should attempt some hill climbs - or bike straight into a stiff headwind.
Can you ride a mountain bike without a derailleur?
Technically, a mountain bike can work without a derailleur. If your derailleur stops working, you can rig it to keep the bike working. However, you also have the option to ditch it completely and make it a single speed, if you wish.
Why are bikes sold with only one gear in front?
Q: Why bikes are being sold with only one gear in front? These bikes are called 1X or OneBY drivelines. They have only a single chainring and a wider ratio rear cassette. Their advantage is that they don't have a front derailleur or shifter.
Can I use 11 speed front derailleur with 10-speed cassette?
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.
Can you use 10-speed front derailleur 11 speed?
It won't work well. It will be able to be adjusted such that it can physically move the chain from ring to ring, but it will be hard or impossible to get it and keep it adjusted so that there's no rub, no sluggish/hesitant shifting, and no propensity for chain drop.
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.
Will any cassette fit my bike?
Yes, almost any bike is compatible with bigger cassettes, bike drivetrain is groupset of components that works in perfect harmony, any miss reconfiguring can break the perfect functionality of the system, parts that need to be changed and reconfigured when putting bigger cassette which is long-chain, wide cage ...
Can I use a 105 cassette with Ultegra?
There's no reason why you can't use an Ultegra cassette with an otherwise 105 groupset, or vice versa. With both 105 and Ultegra, the largest sprocket you can officially use is a 34-tooth, although in truth you can go much larger than that; we have gear systems with 11-40 cassettes that work very happily.
Can I put any 10 speed cassette on my bike?
Yes, if you have a Shimano 10 speed MTB shifter and derailleur and 10 speed cassette it should all work together.
Why the front derailleur is still better for MTB?
“Essentially the front derailleur doubles the number of gear ratios available to a rider, and, therefore, gives riders smaller steps in shifting between their biggest gear and their lowest gear,” he says.
Can I use a double front derailleur on a triple?
"Double" front derailers will work with triples, but if the middle ring is much smaller than the big ring, they will be balky shifting up from the small to the middle chainring. They do, however, work well with "half-step-plus-granny " setups, where the middle ring is only 3-5 teeth smaller than the outer ring.
How do I choose a derailleur?
When buying a new rear derailleur be sure to match it with your drivetrain 'speed'. 10-speed drivetrains use narrower chains than 9-speed so you'll need a mech to match. Most rear mechs are made of a polymer and alloy mix but you'll find carbon fibre in top-end models to shave even more weight.
How do I know what derailleur I need?
The more potential slack, the bigger a derailleur cage you need. For example: If your drivetrain has a 44-22 chainring on the front and a 32-11 cassette on the rear, then... So your drivetrain capacity is 43, which probably falls with the parameters of needing a long cage derailleur.
Can I use any shifter with Shimano derailleur?
Combining with various RDs:
Shimano shifters, whether for 6, 7, 8, or 9 speeds are compatible with all the Shimano RDs for 6 to 9 speeds, and with Shimano 10 speed road RDs (not with 10 speed MTB RDs). Update: a new exception are Shimano Tiagra 4700 road 10-speed shifters, and Shimano GRX gravel series shifters.
