Subject: Sram X.9 or Shimano XT rear derailleur?
I am looking to buy a new derailleur. Could anyone recommended which
one of these would be a better choice, a Sram X.9 or a Shimano XT. I
ride a lot of aggressive cross country with some downhill mixed in.
The most important thing is that it's durable and it needs a strong
cage. Weight is no issue. Thanks for the help, John.

I am currently using XT mechs. on my downhill racing bike and XC bike. (I
also ride aggressively :^) )

Experience with my friends bikes is that Sram mechs break way too easily in
this environment. They usually break off at the main pivot knuckle. Though
they still swear by the Sram stuff, I'd be swearing at it.

Of course, you could buy 10 Deore RD-M511s for the price of one X.0...

I just wanted to mention it for the sake of completeness. But then it
was obviously designed for heavy abuse and all bits are available as
spare parts. If I was interested in heavy mounting biking I probably
would go for a Rohloff hub. On the long run it might be cheaper than
frequent replacement of derailleurs.

Not a bad idea, but they do require proprietary hubs, as the RD mounts
to the wheel axle, not the frame.

It's much cheaper. If you're going to keep breaking them, might as
well be the inexpensive one.

What make the Deore RD different then the LX that I already have? In
what way is it better?

That, and if you have a propensity for breaking stuff, the Deore is
cheaper to replace.

Paris-Roubaix riders ride Chorus, Centaur and Ultegra as much as
Record and Dura-Ace, because it's only going to last the one race. If
they wanted it to last longer, they wouldn't be riding in the P-R.

I currently have a Deore LX derailleur and the last one I had was a
Deore LX. The problem is I keep breaking the cages from hitting them
on rocks and taking hard falls. On my current one the cage is badly
bent. Maybe my hanger isn't working right. Either way I would not
have a problem getting sram shifters if there were a derailleur that
would be more durable. Or should I just deal with
having the replace them more often then I would like. Should I get
another Deore LX or is there something more durable? Thanks again.

Get a cheap one like Deore RD-M511 and take a second one as a
replacement with you. The expensive derailleurs are just more fancy and
lighter, but not stronger. Seals and bearings are better, but that is
obviously not important in your application where resistance to impacts
is the prime factor. An exception is the SRAM X.0 which is rebuildable.

Hard to beat an LX for overall value/durability.

Check out the Saint and Hone parts from Shimano. I think they are made
for tougher applications.

Get the Deore RD (not Deore LX or XT), so you can use your exisitng
shifters. Deore has steel cage instead of alloy.

second that, even if I don't think the cage is steel. No point in
spending money on hard wearing pivots it the piece fails before wear
sets in. And unless SRAM has changed their alloys, their derailleurs
will explode much more spectacular than Shimano's when that branch
decides to cross the road

Every one has put it in a nut shell. Sram is the way I go.

SRAM X.7 or Shimano LX (RD-M580-SGS) have cages made at least partly
from steel while X.9 and XT feature alloy cages. Note that with an SRAM
derailleur you will need a matching shifter.

Both are good, what shifters are you using? The SRAM and Shimano are
not compatible since the cable pull of the shifters is different.
With Shimano you can get a rapid rise, low normal RD which really
shifts nicely. I've tried the SRAM X series, with the 1-1 cable pull
and that is solid as well.

The biggest issue is which shifter you prefer, since they're mutually
incompatible. With XT, you can use a Rapidfire or Dual Control
shifter. With the X9, you can get a twist shifter or a SRAM trigger
shifter, which uses the thumb for both directions, or an upward pull
of the index finger for the release of cable. It's a pretty different
motion compared to the Shimano style.

Of course, SRAM does make a Shimano-compatible shifters that are
otherwise equivalent to the X9 ("Rocket"), but if you like Shimano
shifters, you can't use a SRAM RD. So choose a shifter, and that makes
your choice for you.
