    what do yall think about this deal on 2005 sram x9 rear Der?

    i came across this good deal from bike wagon,
    2005 SRAM X.9 MTB Rear Derailleur 9-speed Medium CageSilver

    its this 05 sram x9 rear der, i was wondering whats the draw backs of 05 to newer ones. is it a good unit compare to a shimano SLX shadow?

    it will be use with 9 sp system, maybe 8sp if i can find a nice 8 sp shifter . i have a brand new SLX shadow waiting to be installed, the shadow one is low pro, direct pull just like sram. mine was somehow a long cage. reading on here. people's experience tend to be lesser chain slap with shorter cage.

    thanks


    also how is the X4 rear shifter compare to x5 x7 x9 just shifting wise, itd go on a comuter/ mild downhill bike where dont need a lot of shifting,

    i wanted to buy the x4 shifter to go with the x9 der with my curernt 8 sp. i dont wanna go to 9 sp cuz i already bought new cassette and chain for my 8sp set up.

    What shifters are you using? If you have Sram 1:1 ratio shifters (x7, x9, x0...) then you can run the x9 rear der. If you have Shimano shifters then you have to run a Shimano RD or Shimano compatible RD from Sram, which the x9 isn't.

    if i buy the x9 rear der, i will buy another x9 rear shifter.

    it's a good deal.. the X9 didn't really change much over the last 10 yrs or so. Got lighter and such but until last yr there wasn't much in the actual performance area.somewhere around 2010-2011 they did start to use a bearing in the cogs instead of the older bushing but that's a good derailleur for the $$$ I may just order one as a back up unit.

    I have the x9 with the grip shifters on my pulse and i love it. Works just as good as my delore/xtr setup on my attitude.

    thats great to hear, i looked up srams rear pair manual of both 05-06 and 10-12, they are minor changes. it just cant go wrong with the X9 for that price.

    i also ordered a green wellgo 107 pedal as a filler item so i can get free shipping. no tax for CA, thats just awesome.

    got my X9 rear der in the mail just now. my initial impression were the weight, it felt like it weighted half of the SLX shadaw. the body and material felt flimsy and kinda plasticy compare to SLX, but the springs were much stronger.


    i think im still gonna go with the X9, its still build well and its super light

    It’s a “medium” size, which may work for you but you may need a “long” instead if you use 3 rings up front.
    The Medium is recommended for the 2x10 the long for 3x10 systems.
    This is because the chain is a shorter length on 2x10 vs. 3x10.

    That's a nice buy. I'd get one ASAP if I had the need for one in the moment.

    Regarding the shifters, I had SX4 shifters stock on my Aniki, and now riding with the X4 and while they are working alright, I'd prefer some X9 with zeroloss shifting. But they are the only 8 speed current SRAM shifters, so I'll have to wait till they crap out to get my X9 and 9 speed cassette/chain.

    I wish they made a little thingy cable pull converter so you could use a 9 speed shifter with a 8 speed setup coz 8 speed stuff is selling cheap ! Still have plenty decent cassettes, rd and chains, but no shifters

    Oh, and difference between a double or triple crankset vs rd cage length is not because the chain is shorter, but it's related to how much chain slack the derailleur need to pick up.

    It's both:
    The chain length must be longer when you have more and larger gears, and this in turn creates more opportunity for slack. RD length is listed in small med or large sizes to accommodate the various systems. There are formulas to calculate how long your chain should be based on your gears. It's possible to put a chain that's too short or too long on your bike's gearing and RD size. The mfg’s do suggest using a long RD for 3x10 and medium for a 2x10 and a short for a 1x9 type system. If you select a RD or chain size too short, then there will be too much tension on the chain and it will likely not shift correctly or stay in the gear you choose. If you choose too long a RD or chain then you will have too much slack and also have problems shifting.

    In fact it goes by the max tooth count capacity of the derailleur.

    Which means you have to do the following maths to know exactly which rd cage length to get :

    (big ring - small ring) + (biggest cog - smallest cog) = max tooth count

    So for a triple crank setup, like a 22-32-44, and a 11-32 cassette, you get :

    (44-22)+(32-11) = 43

    For a double crank like a 24/36 and a 11-32 cassette, you get :

    (36-24)+(32-11) = 33

    For a single ring and 11-32 cassette you get :

    32-11 = 21

    Here's a list of most popular max tooth count capacity for rear derailleurs :

    Long 43~45t
    Medium 33~37t
    Short 28~30t

    And let's remember 10 speed stuff isn't the norm. Plus we are talking here about a 8 speed setup in the OP case.

    havnt come here for few days, thot this thread was dead.

    i just both a brand new x5 8sp shifter from ebay for 18 bucks shipped, its a new take off. good buy IMO. hopefully the X5 shifter is a good match for the X9 rear der.

    i will be running 1x8 speed with a chain guide in the front. im not shifting a lot plus i find 8 sp is way enough for me since i just use like the 3-4 small cogs. i also rarely clime hard, for steep hills i will just get off the bike and run, its much faster than pedaling to death

    i dont get why people need all this speeds, does everyone actually use all tho speed at all?

    i feel like braking and steering is much more important than all those speed.

    Not everyone is a strong rider, and some people need different gears for their location.
    I think Road bikes are more likely to need all the gears.
    As a strong rider off-road I could be very happy with a 2x8 or 2x10 I am certain.
    I am not sure if I would want to go to a 1x10 though.
    I like having faster on straights and a lower speed high torque gear for uphill but I do not think I never use the 11-26 gears.

    I have thought about making my own cassette with just the gears I want, but I'm not even sure where to get the parts.

    To Aka and Schristie,

    I also run a 1x8 on my Aniki, but I do use pretty much all the gearing.

    I also made my own cassette using a Shimano 11-30 and a SRAM 11-32 to get something along this : 11-13-16-20-23-26-30-32 since I have a big bike and lots of uphill riding.

    And more gears means smoother shifting cause the ratio are closer.

    when i was asking if yall use all the gears, i meant do you use like 28 30 32 34 . because when i shift to those gears i feel like i cant pedal any more riding up a steep hill , there is no point for me to have gears like those. im looking to buy a 11-25 or 26 cassette , that would give me much closer ratio .

    Akacoke:
    My riding style is obviously differet than yours: so I would not like a casette like you described.

    Thats probably the reason a 9/10 speed casette is so popular for mfg's because it has a few gears that work for everyone.

    I do not know the details but I am sure there is a way to get a cassette like you want.

    nah, 11-25 or 12 -26 . these are road cassettes. MTB cassettes all have the short gears

    im waiting for a deal to come along, or i will just get one in my next shipment, since im importing

    Well using the Aniki, I sure do grind a bit on the 26-30-32.

    But sometimes I give up cause even pushing a 32-32 (1:1 ratio), I just get too tired and it feel like trying to power a boat... Yeah, 40 pounds of squish doesn't help on the climbs

    And I've seen many 9 speed cassettes like Ultegra or even Dura-Ace go for $20 or less on the bay. Used of course, but still pretty good shape. 8 speed ones are much harder to find these days. Looks like you would be better buying a bunch of old 8 speed MTB ones and built up your own cassette with like 11-12-14-16-18-21-24-26

    Low weight and good ratios

    i got a question tho,

    im buying a sram pg-830 cassette. thats 11, 12, 14, 16, 18, 21, 26, 32

    my current one is a shimano 11 13 15 18 21 24 28 32


    im thinking about making one thats 11 12 13 14 16 18 21 24.

    so i will be taking off the 26 32 off the new cassette adding 24 from my old one. put the 13 from my old one in new one. question is since its different brand would the pin pattern be the same?

    is it bad if i take the pins out completely not run them? i read online some say that the individual rings would dig in the free hub body.

    So this thread got me thinking, which gears are I actually using and what's their tooth count.

    I have a 12-32 cassette (8 speed).
    I find I never use the 12, 28, and 32 gears.
    I stay in the range of 14-26 on the back and use the large and middle rings up front.
    I have been considering goign to a 2x10 because I do not use that smallest front gear, but It's not exactly hurting anything to have it there either.




    I have ordered a new cassette though to go with my SRAM X9 drive train.
    I ordered the SRAM 1070 in 12-32 but after looking at this list below, I think I should have ordered a 12/25 cassette instead.

    FYI: here is a list of the alternate SRAM PG-1070 Cassette's with tooth count.

    The 11/23 includes: 11,12,13,14,15,16,17,19,21,23
    The 11/25 includes: 11,12,13,14,15,17,19,21,23,25
    The 11/26 includes: 11,12,13,14,15,17,19,21,23,26
    The 11/28 includes: 11,12,13,14,15,17,19,22,25,28
    The 11/32 includes: 11,12,13,14,16,18,21,24,28,32
    The 11/36 includes: 11,12,14,16,18,21,24,28,32,36
    The 12/25 includes: 12,13,14,15,16,17,19,21,23,25
    The 12/26 includes: 12,13,14,15,16,17,19,21,23,26
    The 12/27 includes: 12,13,14,15,16,17,19,21,24,27
    The 12/28 includes: 12,13,14,15,16,17,19,22,25,28
    The 12/32 includes: 12,13,14,15,17,19,22,25,28,32
    The 12/36 includes: 12,13,15,17,19,22,25,28,32,36
