Can this derailleur be used to upgrade a Shimano Tourney TX35? This would be on a Genesis Astra that currently has a seven speed rear derailleur. Also, if it can be, can I use the mid-sized version?

No. The pull ratio in the lower end Shimano line, including the road line, has a different ratio from the mountain ten speed line. Also, you're throwing money away for such an upgrade. It's better to buy another bike with OE Shimano XT parts. You can find great deals online and at professional bike stores. This time of the month (January) is liquidation time, too.

This is a 10 speed derailleur and will only work with that kind of setup. In order to use it you will have to update your shifters, cassette and even your front derailleur.

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....

First, I don't know. I have found calling Shimano Customer Service line to be very helpful when I had the same question. But in my experience as long as the number of speeds is the same, and the largest/smallest sprocket size is the same, you should be OK. Again, you should call Shimano to confirm. It is based on the derailleur, and in my case, I discovered from Shimano customer service that I was able to keep my same derailleur when I made my switch.

Yes. The mount on the derailer itself is 35.0mm. Shims are included for 28.6mm and 31.8mm frames.

You can, the maximum cassette range is an 11-34 on this model and above. The STI shift levers work with this derailleur, however, you might want to consider a derailleur with a barrel adjuster to readjust cable tension, like a Shimano Alivio RD M430-9. If not, you'll have to make manual and precise adjustments by hand. This is a great derailleur for its price, performance, and compatibility.

If your rear derailleur will accomodate a 28 tooth gear, this freewheel will work. There is a website www.disraeligears.co.uk, on which you can look up the specs for your derailleur. It is also a good idea to install a new chain with the new freewheel. The old chain has worn in with the old freewheel. A new chain will shift better.

I am not positive, but if you have a matching chainring set (examine sugino attachment confirguration) you should be fine. You shouldn't need to increase your chain length because it sounds like the largest rings are the same size, and the position of the chain and derailleur should stay the same.

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..

Should work. Im using a Shimano TZ20 6 Speed Freewheel on mine which fit perfectly, it should be the same other then it being a 6 speed instead of the 7.

Not sure about using it on a external derailure as I use 3 of these to make up one chain for my trike which has an internal 8 speed rear hub. I checked my bike manufacturer website and called their tech support about it to be sure. Best to consult you bike manufacturer website.

Yes. This is not a whole hub. If you have a 125 spaced shimano hub. This will replace the freehub body. You can run your 7 speed cassette on a modern hub however with a spacer. So really you only need this if your frame/wheel requires a 125mm spaced back end.

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

you can find answers to compatibility issues at the shimano website. you will have to do some searching because there's a lot of data and it will take a moment but you can find it there. i'm not that familiar with all shimano components to give a reliable response.

If your documentation says to use Shimano tool TL-LR15, this should work fine. Note that there's some indication on the forums of quality issues some time ago (3 years I think) where the tolerances weren't very good. No guarantee that there isn't bad stock floating out there -- don't be shy about returning it if you get a bad one.

It will work with Shimano 3x7 front derail. Definitely index shift. I have this shifter and it works As good as more expensive models.

The Shimano Sora 9-speed shifter can be used up to a 50-tooth capacity on the large gear, if you are very careful on the installation, so the cage just clears the teeth when shifting. This is a bottom pull (ie. the cable pulls the linkage from the bottom/lower direction.) I was pleased with this replacement unit, since my original derailleur broke, right at the spring retainer nub, which cannot be repaired.

Yes, the RD-M772 XT was designed as a 9 speed derailleur, so it has the travel range that 9 speed shifters and 9 speed cassettes require. The 772 has stronger springs than older derailleurs, but this should only improve shifting.
