Machka

avtandil

)) sorry about my bad English well commented machka.......

avtandil

but do they come for 9 speed? could not find one

2ndGen

105 5700 is supposedly compatible for with 9 and 10 speeds.

avtandil

what about Shimano Deore SGS RD-M592

avtandil

Front Derailleur - FD-5700 shimano says its for 10 speed is it compatible for 9 speed?

avtandil

i mean front Front Derailleur has anything to do with rear cassette?

What is your gearing? The above would work, but is meant for wider range mtb gearing. If you have road bike type gearing I would stick with road derailleurs. All the Shimano groups were 9 speed at one time, but all have moved on except Sora. But the cable pull ratios and over all cassette width is the same so 10 speed derailleurs should work. The indexing is built in to the shifters and the derailleurs are 'dumb'. An exception may be the DA 7900 stuff, but you won't find that for $100.

It's hard to see, but in your bike pic it looks like you have derailleurs installed. Are they not working well?

dude, you are adorable.

avtandil

1. yes they dont work well the chain fells from derailleur's low wheel ( don't know whats its name) 2. its old and if it will stop working in me middle of my trip that would suck . i am not good with bicycle parts am really noob becasue in my country/ city there is no good shops i am forced to buy things from amazon...and its kind a difficult to choose the right one ( i don't want to buy wrong part) my max budget is 200$ i don't look for light weight i am looking for durable and long lasting but not too heavy

avtandil

ah thank u brother

canam73

Ok, this shouldn't be hard. But what are your shifters, cassette (small and large cogs, should be something like 12-25)) and chainring sizes (should be something like 53/39 or 50/34)

avtandil

lol i dont know how to size them.......checked google but no result.....any idea...

canam73

The size is usually stamped in them, but if nothing else you can count the teeth. On the shifters, what is the model number or name?

avtandil

sorry everything is painted...... size for chain ring is 52 and 42

avtandil

and cassete is 25-12

avtandil

really don't know model of shifters definitely know that shimano

canam73

You have pretty standard road bike gearing and if it's 9 speed shimano it won't be hard to get derailleurs that work. The above suggestion for 105 is a good choice. The current version are 5700 but if you find the 5600 or 5500 they will work, too. If you want to spend less then look for Tiagra (4600, 4500 or 4400) or more it's Ultegra (6700, 6600, 6500). You only need "short cage" unless you think you want to change your cassette to get some easier gears for climbing hills.

avtandil

thank u man, i mean it..... u r very helpful..... if u were on my place and wanted to change whole gear...... which models u would choose? Derailleur front and rear, cassette, chainring, chain cranck, chain and pedals i am not very rich but i could spend some money for good long lasting gear. i will keep levelers and breaks.

canam73

Since you need new RD anyway you could get a medium cage and wider cassette like a 12-30. You might need a new (longer) chain with that, too. You can use either Sram or Shimano 9 speed cassettes and usually the only problem with the cheaper models is that they are heavier. You can probably find one for $30 or so.

The other option is a compact crank with 50/34 rings but that would probably be $100 or so minimum.

avtandil

what if i change 9 speeed cassete with 10 speed?

adriano 

no probs.
