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. Similarly, it is asked, do all derailleurs fit all bikes?
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. Meaning a 7 speed will fit for 5 and 6 speed bikes. An 8 speed will work for 7 and 8 speed.
Beside above, can I use an 11 speed front derailleur work with 10 speed? 10 and 11 speed chain rings are basically the same and are cross compatible. I've got an 11 speed crankset on an otherwise 10 speed bike and it works perfectly.
Beside above, what are the different types of front derailleur?
It's decided by your frame design and where the cable routing leads the cable.
- Top pull. Top pull derailleurs refer to the cable being pulled from the top.
- Bottom pull.
- Dual pull.
- Shimano Side Swing.
- Electronic.
- Low clamp (aka top swing)
- High clamp (aka bottom swing)
- Direct mount (aka DM, high direct mount or H0)
Is SRAM better than Shimano?
Market Share. Currently SRAM are dominating the high-end market, while Shimano service more of the entry-level to mid-range enthusiast segments. In the aftermarket sector the gap is closer between the two, especially at the high-end and flagship level.

Can you use a 9 speed derailleur on a 7 speed bike?
You'll be fine. I had a Deore 9-speed rear derailleur with a no-name Shimano 7-speed cassette and worked fine. The only thing is that you may need a bit more adjustment on the derailleur for the first setup because of the change. How do I know if I need a new derailleur?
If there's play, get a new one. Also, drip some Tri-Flow or something into all the pivots. If it's really dirty and sticky, it'll have a harder time with the shift you describe. If with clean, lubricated pivots the derailleur still won't move well, you probably need a new one. How long should a derailleur last?
3 Answers. Derailleurs will last almost indefinitely. The jockey wheels will wear out in time (tens of thousands of km) but the rest of the mechanism shouldn't see significant wear. What the difference between a short and long cage derailleur?
It's generally best to go for as short a derailleur cage as you can get away with, as long as you can avoid the chain contorting on the extremes of the cassette, such as using the largest on both sprocket and chainring. Smaller cages tend to have snappier gear changes, they're lighter, and also less exposed to damage. What is a 11/28 cassette?
Currently, the most common gearing setup on new road bikes is a 50/34 chainset with an 11-28 cassette. This means that the big and small chainring have 50 and 34 teeth, respectively, and the cassette's smallest cog has 11 teeth and its largest cog has 28 teeth. Can I use a 10 speed derailleur on a 7 speed cassette?
Yes. Except for pre-9-speed (1997) Dura Ace, all Shimano indexed rear derailleurs have the same cable-pull ratio/geometry. As far as number of gears compatibility, if the number of gears in the shifter and the cog match, then the derailleur will go wherever it's told to. Are front derailleurs necessary?
Front mech is not necessary to climb slopes. You can swap out the rear cassette for even larger one if you need lower gearing. You can swap out the rear cassette for even larger one if you need lower gearing. With 10 speed cassettes, you can easily have a rear cog with more teeth than the crank. Can you mix Shimano and SRAM?
Most importantly, YOU CANNOT mix Shimano and SRAM hydraulic brake parts. The SRAM rear derailleur (mech) will not work with a Shimano shifter as is; the cable pull and shift activation ratios are not the same between the two systems. How do front derailleurs work?
The front derailleur is the mechanism that shifts the chain on bike with more than one front chainring. There are many different makes and models, but they all share the same basic design and functionality. Front derailleurs are attached to the bike with either a clamp or bracket. What is band on front derailleur?
There are two types of road front mech mounting: band or braze on. Band: this as the name implies is a band which clamps around the seat tube of the frame. There are two band sizes 31.8mm or 34.9mm so check current model or frame manufacturer's recommendations. Are SRAM and Shimano front derailleurs compatible?
yes, it'll work. caveat: depending on how much smaller your middle ring is, you may have problems shifting up/down. too large a tooth difference can sometimes cause issues here. but the basic question of sram shifter pulling cable for a shimano front mechis easy; it'll work fine. Will a 9 speed front derailleur work with 8 speed?
In practice, they are interchangeable. You can use a 9 speed FD on an 8 speed crank. Do shifters and derailleurs have to match?
No, different maker or different model with different number of "speed" shifters have different pull ratio (i.e. the length of cable pulled by a single shift). Usually it's safe to use different model with same number of gears from the same maker. What is the difference between top pull and bottom pull derailleur?
Traditional front derailers are "bottom-pull", operated by a cable running up from the bottom bracket area to the derailer. "Top-pull" derailers are operated by a cable running down from above. Run the bare cable under the bottom bracket and up to the derailer's anchor bolt. What is the crank arm?
: crank web specifically : the offset portion of a crankshaft to which connecting rod and piston are attached. What is a down swing front derailleur?
Down swing/up swing refers to the geometry of the derailleurs swing. An easy way to tell the difference, a bottom (down) swing derailleur has the clamp above the derailleur. This is often referred to as a traditional derailleur as all derailleurs were this way at one time. When was the front derailleur invented?
In 1895 Frenchman Jean Loubeyre patented a device for derailing the chain from one sprocket to another. He called it the Polyceler (multispeed).” The derailleur was developed in France in the early 20th century, but it wasn't actually until the 1930s that European racing organizations allowed gearing to be used. Can I use a triple front derailleur on a double?
The only difference I see between a triple and a double front derailleur is the extended inner plate of the former, which assists shifting between the inner and middle chainrings. As long as the limit screws can be adjusted properly, I don't see why it would not work on a double setup. Nope. What size derailleur do I need?
Range is the difference between your biggest and smallest cog. To use an example, if you have a triple crankset with teeth ranging from 22 to 44, or a cassette with a large cog bigger than 32, you'll need a medium or long cage rear derailleur to take up the extra slack between your biggest and smallest gears. Are 10 and 11 speed chains the same?
11 speeds. Chain width is 5.62 mm. 11 speed chains of all the manufacturers are mutually compatible. Since 10 and 11 speed chains are almost the same width, as well as cassette teeth, 10 speed chain can be used in stead of 11 speed one, without it jamming between the sprockets. Are 10 and 11 speed chainrings the same?
The spacing between 11-speed chainring teeth centers is not narrower than on 10-speed chainrings. In some cases, it is even a bit wider on 11-speed. So your system will perform pretty much the same as it does now if you were to replace your 10-speed chainrings with 11-speed ones. What is the difference between 10 speed and 11 speed?
Tighter spacing on cassettes AND wider range from top to bottom of cassette are possible in the same cassette with 11 vs 10. This can make a pretty big difference when climbing. 4. The 11 speed stuff just shifts better than the comparable line of 10 speed components, it's actually quite noticeable. Are 11 and 12 speed chainrings the same?
The chainring on a 1x system will only "see" the internal of the chain, so yes, a 11 speed chain will work fine with a 12 speed chainring (that's usually 11/12sp chainring). Are Shimano 9 and 10 speed compatibility?
The 9 speed shadow(Shimano mtn) rear derailleur will work fine with road 10 speed shifters. Are all 11 speed cassettes compatible?
And, as I've said before, there is 100 percent shifting compatibility between 11-speed cassettes. In other words, Shimano, SRAM, and Campagnolo 11-speed cassettes work just fine on each others' drivetrains. Can you use an 11 speed shifter on a 10 speed cassette?
No, that will not work. The shifts will not line up across the entire range, because an 11-speed cassette is not just a 10-speed cassette with an extra cog stuck on at the same spacing. Can you use a 10 speed crankset with 9 speed?
The 10 speed chain rings will be fine with a 9 speed chain running on them. The problem you will have is the spacing between the chain rings. The 10 speed rings sit closer together than they do on the 9 speed. Can I use 11 speed derailleur with 9 speed cassette?
No, an 11 speed road shifter has a different pull ratio than an 8, 9 or 10 speed. Any 8, 9 or 10 speed road shifter will work with any 8, 9 or 10 speed road rear derailleur (unless it's Tiagra 4700). However, the 11 speed road system pulls more cable per shift and therefore is not backwards compatible.
