    SRAM X9 and X0 rear deraileur

    So I am building up a new FS, and I decided to go with the SRAM grip shifters and say goodbye to the Shimano LX crap.

    The thing is, every time I see a Ellsworth, Yeti, Titus, Ventana and other nice FS bikes, they are usually customized, meaning that a person built it up with their custom specs. They always have SRAM X.0 Rear deraileur.

    My LBS told me that they would recommend the X.9, identical in shift quality, just few grams heavier. It really doesn't matter, as he puts it.

    I don't think all of those people who have X.0 rears are hardcore racers that would mind the few gram difference. So to those people, why did you get the X.0?

    Is it for the "bling?" I don't think the weight is signficant enough to justify the super expensive price tag, especially for the 06 with the carbon cage. (Saves 10g from 05 model, wow that's heavy. ) Or am I missing something else?

    I have a x9 but I don't have any experience with a xo. From what I have read the xo is slightly better than a x9 but for the price I would't buy it. Get a x9 and some flak jacket cables or somthing similar, cables make a big difference. So if you don't want to pay xxx more for bling, weight savings, and slight peformance increase stick with a x9 and some good cables.

    X0 came with my bike

    with X9 shifters. Otherwise, I would've spec'd an XT RD while keeping the X9 shifters... Heck, an XTR RD would be cheaper than the X0...

    Except you'd have to change over to the Rocket trigger shifters if you were using any non-SRAM rear derailleur. The cable pull ratio is different.




    I use X9 and didn't think XO was worth it for my applications. I've had no issues with my x9 derailleur and x9 triggers and flak jacket cables. Full housing all the way and has been super smooth going on 5 months now with no adjustments needed.

    Hmm, why is pricepoint selling the X.7 Attack triggers with a Shimano LX RD?

    Because they mistakenly said "X7".

    yep... they goofed and put x7 on the name.

    attack and rocket shifters are for 2:1 ratio rear derailleurs

    how do cables make such a big difference?

    Don't count out X0 rear D's. They are quite a bit stronger than X9's and stay tighter for longer. I've hit my X0 so many times and its still true, can't say that for the X9. Not to mention, they are totally rebuildable.

    the cables such as avid full metal jackets make the buttons on the shifter lighter since there is less pulling resistence in the cable.

    The X9 and X.0 are basically the same derailleur. You should not notice any actual shifting difference between the two. The difference is in the construction. The X.9 is a die cast part while the X.0 is forged and better refined in use of materials to save weight. That makes the X.0 lighter and stronger except for one small issue. The plastic knuckle used in the X.0 becomes a weak link.

    I have been using the X9 RD which broke twice, but sram replaced it both times so not a big deal now. Shifts great, better than the xtr that I have been using. Tried the XO RD on my friend's bike, couldn't tell the difference in shifting performance for the short duration that I had used them. IMO, why drop the extra dough on XO unless you are worried about weight, you can buy a few X9's for the price of XO and never worry about spares.

    There's nothing like a new set of cables and housings... can dramatically improve shifting performance & drivetrain probs and is often overlooked. I think the avid flak jacket housings are junk though.

    What would you say the best ones are? I have some Jagwire ones right now, not sure what they are. I don't think theyre teflon coated inside, and I'm sure that makes quite a difference. I just got an X-9 shifter for christmas, and when taking my X-7 off, I noticed a big difference on how the cables felt...I think the x-9's are teflon coated? All I did was reuse the same cable housing for my x-9's...bad? But yeah, which ones would you recommend?

    Just good ole stock coated stainless steel cables and 4 or 5mm housing. I've used and worked on all the fancy shmancy cables out there, some of them actually turn worse than a "standard" setup when you get a little dirt or grit in there, some of the coatings decay and turn into friction-devices, and some of the "benefits" are just to marginal to ever justify the price. Instead, take that money and just completely rip out the cables and housings and replace them more often. That is where you'll see the most benefit. Things happen, cables or housings get caught on branches or things, they get kinked, etc. I just completely rip out my "system" every 6 months or so. If I'm working on a bike that shows a bit of friction or drag in the cables, it's not worth my time to try and make the derailer work, it's never going to work right. I completely junk the cables and housing and start out fresh. It's not being excessive, it's just simply what's needed usually.

    well said Jayem...

    I've had great results with jagwire cables/housings and they're not too expensive.

    bottom line, cables and housings wear out, usually before they break and should be replaced. If you just put new shifters on, I'd definately run some new housings if they're more than a few months old... if you haven't replaced housings in a while, you will notice improved shifting performance with new ones.
