    Lefty Fork change for 2012?

    I tried to order a 2011 29er carbon XLR fork for my new build and the lbs said they were sold out. He siad I could either get a regular carbon XLR with a reducer added or wait for the 2012 that would be ready by early July. He said the 2012 fork is suppossed to have a change to help with bearing migration - can anybody confirm this? I went ahead and ordered the 2012 fork and my estimated delivery date is 7/9.

    That's not a long wait if it is true.
    Maybe Cannondale is taking the MTBR member's advice of moving the split rings above the damper to alleviate migration

    Although I have no info to back up my feeling on this, I'm going to say that it sounds like just a weird sales pitch by your dealer.

    All these years, it continues to exist as a natural part of needle bearing design. They've made it super easy to reset, I can't see them spending time to do more in that regard.

    Not that I'm an engineer, but I'm not seeing any way, design or mechanical, to prevent it from occurring, and believe me, I spend more than a few minutes around these things every day

    That must be it Yogi, the auto reset function we've all been waiting for...

    Just confirmation.

    There are no significant changes for 2012 Leftys. 2011 was "the big change" year, platform damping for all models, re-structuring of travel to 100, 120, 140, low speed compression, etc.

    I'm guessing we'll see things stay static for another year or two. I applaud that mindset too. Way too many companies are changing, every year, and for what, just to sell you on what's new, and make you dump what is perfectly good. Let's face it, if you have a smile on your face, do you really need a new widget every year, so some wealthy, disconnected board of directors member can keep up with their house boat payments?

    Straight from the horses mouth (sorry D, I know you're not really a horse!) "the only changes for 2012 Leftys will be to go from white to black".

    I guess he's talking about the alloy models or maybe the crowns.
    Either way, I can't see how they would improve much on the 2011s unless they got tighter on the quality control end of the assembly/manufacturing not that it is at all bad now but that can always be improved upon.

    Edit: I can see going to Post Mount as being a definite upgrade.

    Thanks for the info! On a related note, the same regional rep said that a fork with frequent migration can be corrected by sending it back in for larger races - is that true?

    Correct, but let me be concise. It will never be "fixed" or prevented, or stopped. Nor will you ever have a fork that doesn't require some attention in this regard from time to time.

    The thicker the races, the stiffer the action. Not horribly so, but different. They try to build them fairly light at the factory, so you get that super fast, wicked plush small bump performance, and since they are so easy to reset now, it's their mindset that folks will simply reset as needed.

    However, certain situations, riders, styles of ride, etc, may lead to really frequent resets, like every ride or three. Some folks love the ride qualities at the given preload, so the resets are not a bother. If it is for you, or someone you know, yes it can be dealt with to make it more like every couple weeks, months, what have you, but still based on personal ride factors, so it may take a time or two to get it nailed just right for you.

    In my experience, ( I do re-tweak many of these a year, though most forks sent to me I just service or repair) there is at least one or two steps firmer that a fork can be pushed to, before becoming too tight to be good feeling.

    I personally like mine a little on the slow side of the spectrum for technical riding. I find if it is set so the bearing preload is low, the damper doesn't control the action as I like even with 7.5 wt. oil. We have a ton of large rocks here in Northern New Mexico and it take a lot of maneuvering to get around or over them.

    I haven't tried treaking it with the slow speed ports, but I have the added benifit of having to do less resets if I add a thousanths or two to the inner races and the feel I am looking for is accomplished by doing so.

    Yeah, preload seems a good half step towards LS comp damping control. The 2011 damper LS comp adjustment didn't work well for me (it did work as intended, just not what I liked), but I'm spoiled, and like the uber small bump I get out of it at the fully open setting. Even one step down really affected the overall trail feel, at least in terms of what I like and the trails I ride....

    You cant just by new clamps for that lefty, you will need a whole new upper assembly. I think Cannondale would want to do this for you. If I remember correctly, Aluminum runs about $300 before labor charges and I'm sure carbon is more. This is if you have a non OPI lefty though.

    Not knowing what cracked, impossible to give you any idea on fixes etc, but I can say with sound mind that $800 to check it out is near the cost of a new fork, and that shop in question doesn't know their rear end from a hole in the ground.

    That's the third one of these on this forum in a month. Here is a thread about another one a month ago. Cracked upper fork crown

    You cannot go directly through Cannondale, but there is another route. There is a guy upstate that works on Leftys and he could get you going quick for less than half of what your shop is trying to charge you. His name is Craig Smith and he has a shop in Mendon, NY and he just relied to your post above. His link is at the bottom of his post....give him a call.
