Recommended Posts

want to order a derrailleur from CRC.

 

it's SRAM X.o (will get the levers as well) .... i have no idea what cage length i need.

 

 

 

it comes in long, medium and super-short. i assume it's not super-short (it looks a bit roadie-ish) - so do i need medium or long?

 

 

 

it's a giant trance, i have Shimano XT on there, but nowhere on that cage do i find a length.

if you asked a roadie question about which one for the road bike, i might have been able to help.

 

this is clearly for your mtb, so id rather not give you my roadie advice Wink

for mtb will generally be long cage, I think only meduim, short it you have smaller cassette ?and chain ring range, - but thats just my guess. I recently got X.9 Long Cage RD withr Redwin Red 11-34 Cassette and its all good. Did you consider the Twisters or are you sold on levers?

super short is for DH...

 

I use med, and have no problem.

 

Using long cage you can use a wider range of gears (eg bigger than 44 on the fron or bigger than 32 on the back)

you also have to be more weary of 'cross chaining' on a med cage der.... that's when you're in the big ring on both the front and back, which stretched the der. to it's max - which is obviously is longer on a long cage der.

Here are the general rules for rear derailleurs:

 

 

 

Long Cage - 3 blade crank (ie Std MTB crank)

 

Medium Cage - 2 or 1 blade crank

 

Short Cage - 1 blade crank

If you have an 11-34 cassette a medium will suffice, unless you like to cross-chain badly in the big blade and the 34 (not good)

 

Generally if you ride a straight-ish chain you wont need a long cage. The medium will keep the chainslap down to a minimum over the short cage too.

 

Short cages are nice for racers who keep there gears low and ride a 32t max

Hi cat-i

 

Solomons have the SRAM XO RD advertised on special in their latest flyer for R999.95

 

last time I looked they were about 1350 at CRC so you might be to save a bit there and get it quicker

 

As above with 3 blade crank I would go for the long cage

 

Cheers

Thanks crasher. Was looking for a X0. A SECONDHAND ONE BEING ADVERTISED FOR R 1100... I just made the eft to Solomons. A bargain. They only have the medium cage.

 

The original question:

The safest answer is a long cage for a 34 cassette. BUT I have used a med cage X9 that came standard with a Giant Trance (11-34) without any problems. I generally try not to cross chain though.

The ones from Solomons flyer is the 2007 model - still a huge bargain though!

I see they sell the 2008 for R1699.95
