Rated 5 out of 5 by Шикарен ВАЖНО! Ставил GS (средняя лапка) на трансмиссию 44-22/11-32. Работает превосходно! Единственное ограничение - на звезде системы 22 не может выбрать провис на 11- и 12-зубых звездах кассеты (8,9). Данные соотношения считаю неприемлемыми и нелогичными ввиду порядка переключения, поэтому рекомендую к покупке версию GS - меньше вес и выше от земли! 21 June 2014

Answers

Answer: 
The quickest way to identify required cage length is simply to count the number of chainrings on your crank; a single ring crank requires a Short cage mech, double requires Medium and triple requires Long cage.

Yes no problem; the long cage rear mech will be fine on your Triple ring setup. All the Shimano 9 Speed MTB components used the same technologies, so are all cross-compatible for the most part.

Answer: 
The cage requirements on a derailleur (for a Mountain Bike) are relative to how much chain movement and tension will be required when shifting through gears.

Short Cage - For use with a Single Ring Crankset.
Medium Cage - For use with a Double Ring Crankset.
Long Cage - For use with a Triple Ring Crankset.

Answers

Answer: 
Yes; your original Shimano mech can be replaced with a Shadow or Shadow+ without any problem. Shadow technology simply runs a lower profile to reduce the risk of damage by trail debris, and less chain movement to help avoid chain drops etc.

As you are only running a single ring up front you will be able to fit a short cage or medium cage.

A short cage would be more appropriate for downhill applications.

Answers

Answer: 
This Shimano Mech is not compatible with SRAM Shifters due to a variation in pull ratio (this is the case with most SRAM and Shimano derailleur/shifter combinations).

It would be advisable to upgrade the mech to a higher tier SRAM variant if upgrading the drivetrain is the intention and the shifters are functioning correctly.

Answer: 
some say mixed brands (shimano with sram) works better than having all shimano or all sram. sram X9 is like shimano Deore...as X0 like XT and XX0 like XTR.

everything is compatible as long as you maintain shifters, chain and cassette for the same number of speeds. currently, as for my road ou mtb, both derraileurs are 10 speed but all the rest (shifters, chain and cassette) ate the same so it works perfectly. the shifters command every gear and thats the way you have to go.

1 click on 9 speed shifter is larger than a 10 speed click, you may not see because it's something like 0.50 of difference but in the bike you can hear and feel the bad shifting.

I had a Rocky Mountain RCle (2007) Hybrid but it broke at the derailleur dropout so I lost the frame and rear derailleur (Alivio 8 speed). The replacement frame is an RC30 (2009) which used the Deore (not sure if SL, SLX, XT, etc). I want to upgrade to a Deore XT since I have to replace the derailleur anyway.

The front ring is 28,38,48 from the RCle. Front derailleur is now a Shimamo FD-443 (I think) as the old derailleur would not fit the larger tube diameter.
The rear cassette is 11 to 30 teeth (8 speed).

I assume I need the long cage (SGS) to allow sufficient range in chain length.

I know that 10 speeds need narrower indexing so not compatible. But some sources say that all 7,8,9 speeds have the same indexing movement (just different number of indents) so a 9 speed should be able to be used with an 8 speed casette. Some 9 speeds say 8/9 speed (ie. the Deore SL) and some don't like the DX. I want to only upgrade the rear derailleur, keeping shifter, cables and chain to minimized cost.

Can you confirm my understanding or clarify? The XT would be ok for use or not?

Answer: 
This mech will be fine to run with an 8-speed cassette but will require some minor adjustment when setting it up.

As a triple crankset is being used, the Long Cage variant would be advised.
