Is this compatible with 9 speed systems? or is it different actuation? (I need 1:1) they don't seem to make 9 speed clutched derailleurs.

I would not expect it to work for 9 speed. I have found that the clutched version can be temperamental. Every now an then it behaves odd and chain slips on the front ring. I don't see any benefit from the clutch version. Maybe I don't have it set correctly. If I slacken it of then it will be just like a non clutched version.

I agree with Michael B Hare's answer. It is not within Shimano spec, but it MAY very well work depending on the geometry of your derailleur hanger. Sometimes it won't, but there are a lot of reports saying this combination works fine. MBH is also correct in his warning about chain length....

No. That said, KMC has Missing LInks for 9 speeds. You really need to find the model of your chain and look up the specs. Make sure the chain widths are the same. Even a Missing Link for 9 speed may not work if it is thinner than your chain width.

your current derailer should work, you may have to move it up a bit on the frame, but should be no problems

Yes it will. The pull ratio is not 1:1-- this has the same ratio as all older Shimano ders. The only problem you might have is if you run a slightly wider chain through it. I don't think it will jam up or anything crazy like that, but you might get a little rubbing on the cage as the chain deflection increases (i.e. while you're cross chained). Just run a 9-speed chain and you'll be completely okay. Again, not that the 8-speed chain is going to lead to a catastrophe. Shimano did change their pull ratio when they moved their mountain drive trains to 10-speed. This is a little annoying, but at least there are more modern 9-speed options available (10-speed road ders will still work on lower-speed mountain drivetrains, though. I'm running a 10-speed 105 der on a 7 speed drive train with an indexed shifter :) ).

I recommend doing some reading. Short answer is they allow for different big big and small small gear combinations. Look here for a good explanation. http://forums.mtbr.com/drivetrain-shifters-derailleurs-cranks/when-use-long-cage-vs-short-cage-derailleur-205890.html Figure out what gears you plan on running up front and in back and then choose the appropriate cage per manufacture recommendation. I hope this helps

You would need a 10 sped chain (thinner than 9 sped to fit the 10 speed cogs) Also you may need a different front derailleur if going from a double to a triple Shimano has a Web site technical documents specifications or call Shimano technical departmeant

NO! Absolutely not! This is a SRAM 1:1 pull ratio shifter that works with SRAM 1:1 ratio rear derailleurs NOT SHIMANO!!!!! It will work with a SRAM rear derailleur & a shimano cassette but NOT THE OTHER WAY AROUND. Period.

I would think so. As long as the derailleur supports at least as many speeds as you have.

Did some quick Googling and it looks like the Shimano 10 Speed Dynasys components are not compatible with any other style/brands including Ultegra. They used to be but not any more. Just basing this off of research.

Dear Juice: There are two systems. One is the older-style freewheel where the cog unit goes screwed on the hub of the rear wheel. This Shimano Tourney is one of those screw-on cogs. The newer system is where the cog unit -called a cassette- goes pushed and then locked on a splined extension of the hub. Both systems are not compatible. My advise is get a bike mechanic or a friend who knows the difference between the two systems have a look at your bike and tell you which system it has before you spend the money :-) Hope this helps, Andy :-)

I would not be inclined to try it, the 10 speed chains run best on 10 speed gears, on the "less" gears while I know you can put a 10 speed chain on a 9 speed cassette it is more difficult to maintain / tune as the 10 is a narrower chain so from my experience I would not try it, the KMC is a beautiful chain for the 10 speeds. KMC does make 7/8 speed chains for the thicker gears, but I am not sure they have it in colors the KMC model I think for 7/8 is the Z51 that is set for 6/7/8 speed specifically, I would be inclined to go that way for the KMC chain

I put a 7 speed freewheel on this wheel and it works great. 6 will work too. I am assuming you have the old 27 inch, 126mm hub config like most road bikes of the 1970s and 1980s.

if you have a 7 speed rear cand a 3 speed at the pedal this will work. I don't know anything and it was easy. Down load the instructions on adjusting the gears. It's like canything else,3 hours the vfirst time and 1 hour evetry time after that. it's easy and fun. save bucks too..good luck.619-540-7766/paul

I second the comment that cassettes for 7, 8, and 9 are compatible usually on the same hub. Your derailleur and shifters will determine how many of the gears in the cassette will be used.

I assume you mean your shifters only have 7 positions. With an 8 cog cassette you would set the the limits of the shifters to leave out either the smallest or biggest cog, i.e. you will be able to shift to 7 of the 8 cogs. But, you would be better off just using a 7 speed cassette.

It should adjust to fit BUT a lot depends upon your shifters, cables etc.... If you have thumb shifters I think it will work. I have seen a 7 speed Shimano click shifter work but of course it had to be adjusted to fit...I use new 6 speed twist shifters and cables when I work on a bike. For this job the time the old derailleurs will work most of the time.. It's not a big difference going from 5 to 6 speed but I don't think 7 is worth the trouble... I have stopped using this particular cassette and now use the 34 teeth low speed since our local area has some big hills......Good luck..
