Shimano rapidfire shifts SRAM X.7 rear

    Hi everyone,

    Looking to replace my severely busted Shimano LX rear derailleur, the
    bike shop I frequent to tried to steer me into getting a SRAM X.7.
    It's better quality and it's slightly cheaper than a new LX. Question
    is, I have a STX-RC 8 speed rapidfire and she claimed that this will
    work with the X.7. She swore by it because their mechanic installed
    these on several Shimano shifter equipped bikes already.

    I'm a little apprehensive about this because, it made no mention on the
    box that it's Shimano compatible. It's ESP 1:1 on the SRAM website.
    The shop people were quite adamant that it will work, but to guarantee
    compatibility, they will have to install it for me.

    Who should I believe?

    Yes, there are SRAM changers which would work in your system
    but, no, X.7 isn't one of them.

    SRAM products with ESP printed on the derailleur are 1:1
    cable travel models . Those require an ESP shifter.

    MRX series SRAM changers are Shimano compatible. SRAM seems
    to have truncated their Shimano compatible line to just the
    one (MRX) model.

    Do ride an ESP bike, though. You might like that X.7 with an
    ESP shifter set.

    p.s., regarding price, LX M570S and X7 cost exactly the same
    so it should not be much cheaper.

    you can get a x9 dr and trigger or grip shifters new for 100.00 to 120.00 right
    now.

    I'm new to this ESP stuff and am willing to switch from my Shimano
    STX-RC system over to it. But I have a fairly tight budget, so I am
    sticking with 8 speed cos I can get the cogs and chains (SRAM stuff for
    50% cheaper than ShimaNO equivalent here). Will an 8 speed ESP shifter
    (gripshift AMY I'm looking at now) shift the X.7 rear derailleur ok on
    a 8 speed Shimano cogset that I have now?
    The reason I'm asking this is, my current STX-RC is just about to die.
    The return spring was fixed twice and it's failing again, so I'm
    planning to kill 2 birds with one stone at the best possible price.

    Here, the X.7 is $3 cheaper than the 570 and way cheaper than the new
    580. Speaking of which, is the LX 580 any better than the 570 to
    justify its price?

    Steve,

    I'm trying to keep it 8 speed as possible and I found I can get the ESP
    7.0 or 9.0 grip shifter (rear only) plus a X.7 rear for about $55 to 65
    by mail. I don't mind trying gripshift after riding with rapid fires
    for 6 years. I think it should shift ok with an 8 speed shimano
    cassette?

    Yes, an SRAM ESP shifter (any of them, trigger or grip) will shift the
    x7 der just fine. I would strongly recommend trying the gripshift out
    before swapping to it, though. My personal opinion of gripshifts in
    general is that they are material to be supplied to one's competition
    in the largest possible quantities. I will admit that the SRAM
    gripshift for their ESP rear ders is nowhere near as objectionable as
    any of the Shimano-compatible gripshifts I've tried, but it still
    isn't to my taste. That said, I've installed a couple of sets for
    friends, and they seem to work well. For those who like this type of
    setup, the SRAM twist-grip seems to be a good choice. (And obviously,
    for trigger-happy types like me, they're not.)

    Shop all of these components around. You may find some surprises.

    He he. Depends on how much you value 'shifts backwards' as
    either a gimick or an improvemnet. It's worth it to somebody!
    In fairness, backwards shifting not only works but in some
    ways is better. You should ride one. If you like that, the
    M580 is _way_ nicer than a Suntour Skitter but nowhere near
    as pretty.

    SRAM offers both trigger and twist at several price points
    for six, seven , eight and nine. 8sp from under $30/pair.

    ESP is a format for cable travel and relates to the
    coordination between shifter amd changer. Both SIS and ESP
    use the same cassette spacings. Yes an ESP-8 shifter and ESP
    changer will shift properly with a Shimano, SRAM or SunRace
    cassette.

    At the very basic end, Shimano has kept 7sp HG50 cassettes
    at a low price, hurting SunRace a lot. But in mid price and
    top end cassettes I like SRAM. Take a look at a SRAM 970
    from the back side. Pretty, eh? Cheaper and lighter too.

    (In theory, the drawback of a no-spider design is that under
    high loads on an aluminum body, the cogs might dig in and
    rattle. That's uncommon and I'm not sure it actually hurts
    anything)

    Yeah, that was pretty general. X7 and Attack triggers in 8
    or 9, twist in 6 through 9. No tens.
    Twist start under $30, triggers start around $70.
    SRAM shifters are readily available in singles

    I had used Gripshifts before on my first hardtail bike. It was the
    Gripshift SRT-800 and they are great, except for reliability. I heard
    that the current 7.0 and 9.0 Gripshifts are of better quality?

    Can you tell me where I can find SRAM 8 speed triggers?

    We have 'em
    (for ESP and for SIS)
