    This above setup shifts and works ok MOST of the time...however.... there are some annoying times
    when it will slip and spin not engaging correctly changing from granny gear to middle gear. Also,
    when pedal force is increased a lot all of a sudden, the rear sprocket will ever so often go down a
    gear (which really sucks btw). And sometimes going from middle ring to granny ring over bumps causes
    the chain to go too far and come off.

    Most of the time it works great and operator error or hast is usually to blame but it would sure be
    nice if it would be more consistant.

    Is there any setup(XTR?) that works like butter, shifts and operates crisply and precisely 98% of
    the time instead of 85%? Or do all shifter setups, including the best high dollar ones, have minor
    hicups now and then even when in good tune?

    Bonty cranks have a rep for crappy shifting.

    IIRC, you have FS. It could be that your rear mech cable is too short, so that when the suspension
    extends under force, the cable tightens and your bike 'ghost' shifts.

    My SRAM stuff works lovely.

    There is no perfect set up. But with proper adjustment your components should work ok. Check
    out: sheldonbrown.comderailer adjustment.html or Zinn's book. Also in my experience
    replacing or upgrading worn cable makes a remarkable difference. It also helps to keep your
    chain and cogs clean and replace when worn.

    Like bomba said, Bontrager chainrings just don't shift too well. Deore shifters on a deore front
    mech doesn't make for he most bulletproof setup, either. In my experience there is a lot of
    inconsistencies in anything LX and below. Front derailleurs, though, just simply don't work very
    well...especially when compared to rear shifting. It takes a lot of adjustment to keep it perfect.
    If you're having problems getting into the middle ring it sounds like a cable tension problem to
    me...remember there is a such thing as too much.

    I use XT shifters with an XTR front and an XT rear, and I haven't bonked a shift in a long time.
    This is mostly due to my regular cleaning/lubing/adjusting of the drivetrain. After every ride I
    clean the chain and cogs and spin through all the ear combos on the workstand, and tweak what's
    necessary. That's the only way.

    That's why I loved my Sachs PC-91 (Sram now??) chain so much. Yank it off to soak in WD-40 after
    every ride (only way to get the White Lightening off). The drive train was also cleaned as well. Put
    it all back together, relube, and readjust if needed. I'm really anal about keeping my gear well
    maintained, and it always paid off on the trail with no problems, and flawless shifts, even with the
    lower end stuff.

    I run XT shifters, XTR front/rear der's, cassette and cranks on my hardtail; I run XTR shifters, XT
    Front/XTR rear ders, XT cassette and cranks on my fully. I'd say that I can definitely notice a much
    smoother shifting action from the XTR shifters on my fully. I don't notice much of a difference on
    the front derailler (XT vs XTR) or the XTR cranks or cassette (save your money unless you're a
    weight weenie). I would consider the shifting on both my mtb's to be excellent, and it almost never
    is even something I have to think about on the bike.

    That said, I am a firm believer that for most recreational riders, LX/XT are more than adequate (not
    too sure about Deore stuff), provided the cables and drivetrain are maintained properly. That means
    replacing or at least cleaning the cables/housing on a regular basis (or using Goretex Ride-ons or
    similar more "sealed" cables). Frequency will depend on the conditions. Could be one ride, could be
    6 months. You'll also need to be sure the housing lengths are correct. A good mechanic can help you
    with this.

    I know people who run and love their SRAM stuff, and I think the Shimano monopoly needs some
    competition. I'm not too crazy about all the plastic on the SRAM stuff, though. Also, going with a
    notch higher rear der is always a good idea, given the workout it gets compared to the rest. (eg. XT
    rear on an LX drivetrain)

    Not to start a lube flame war...just passing along my experiences:

    On my drivetrains, I use Pro-Link Gold lube, except in the wettest of conditions on all my bikes
    (road included). One drop per roller before every ride, then run thru all the gears. This lets the
    lube penetrate the links and helps bring the junk out of the internal parts and to the plate
    surfaces. Then I wipe the excess lube and goop off the plates with a rag. I know this process is a
    bit anal for some, but it works for me.

    For those less inclined to maintenance, I'd suggest using White Lightning, given its self-cleaning
    properties. Just be sure to use it often (after every ride would be a good idea). For it to be
    effective, you'll need to lube up several hours before riding (overnight) - which is the main reason
    I switched.

    In either case, it never hurts to occasionally break everything down and degrease (Simple Green for
    me) everything, scrub it all with a toothbrush and reassemble. Like the cables, the frequency will
    always vary with riding conditions. You can't do it too often. Don't forget to change your chain
    when it hits about 1/16th in. of stretch over 12" section. That'll really extend the life of your
    chainrings and cassette as well. I like the SRAM chains for the quick disconnect link. PC-59's are
    about $15 and I have broken only one- and that was my fault. Clydes may like a stronger version -
    I'm a skinny racer type.

    Someday someone's gonna figure out a way to transmit power from crank to wheel without all these
    exposed items. That guy's going to be a millionaire! I just don't know what I'll do with all that
    extra time - ride a little longer, I suppose...

    I've had primarily LX & XT (lately all XT) on my last couple bikes, and it was OK. I didn't know
    there was anything better. Then I switched to SRAM, and the latest rear derraileur on my red bike, a
    5.0 something, is amazing. Within no more than a quarter turn of the cranks, I'm on. Still have XT
    up front, so it's a good thing I don't use the granny or big ring very often. It's just too slow and
    temperamental for me.

    Maybe that's why 4/5's of my riding is on the Singlespeed.

    Cool. Thanks for the link.

    Thanks all for the info too. Guess my shifter equipment is probably working as is should considering
    its quality and specs. Get what you pay for. Someday I'll upgrade but for now I'll just have to pay
    a bit more attention to maintance and how I shift.
