    New question here. Bad Lefty Failure..

    First, The last thing I want this to turn into is a Lefty bashing thread.. I have two lefty's myself and dont see that changing. I did want to put this out there to see if: 1) anyone has seen anything like this before 2) in the event this happens to anyone again.

    I wasnt present when this occurred, but have met the racers and other racers who were present. It occurred during a state XC racing series (FSC/ Florida State Championship racing series) at Ft Clinch State Park, Fernandina Beach, FL. The racer was going "downhill" (a term I use loosely since this IS Florida after all, and it was an XC race).

    The racer was in Cat 2 40-49. He was injured; fracturing his sternum, jaw, and a vertebrae, along with breaking at least one of his teeth. He was airlifted from the scene and required surgery.

    He was riding a 2011 or 2012 29er Scalpel with an aluminum Lefty.



    Now if youre familiar with a Lefty, you know that particular area of the clamp appears to have holes on the underside, maybe to shed more weight? A picture of the underside of the clamps from my own personal bike:


    So has anyone ever seen a failure like this? When I heard the failure, then saw the pictures, I was surprised as it was not where I would have expected.

    I've pictured something like that happening when riding, but never seen or heard about anything remotely like it until now. My oldest lefty is a 2004 and it works like a charm.

    More pics of the damage and of where it happened would be needed to even make an uneducated guess.

    A friend of mine sent me this pic knowing I have a Lefty on my Flash Carbon 29r. I still feel there is more to this story then what we actually know about. I am guessing that he either hit something before the fall at speed, or the fork was damaged in someway before this race. I have a hard time believing it just broke causing the fall. I hope there is a way we can eventually get the full story. I know I will be checking out my fork before every ride, but I am not going to be afraid to ride it at all.

    More information will surface with time. Unfortunately the rider is still in the hospital. The only updates are of his medical status. Im sure once he is out and mobile again, we will have additional pictures and information. Since it was the first lap of a 3 lap race, he was probably in a pack, so there might even be video of the incident.

    here is a video of a race from the prior year, so you can get an idea of what the terrain is like: FSC#2 Ft Clinch State Park - Fernandina Beach, Expert FL 40 to 49 - YouTube

    Ouch.

    My only guess would be that someone over tightened the ever lovin' piss out of the clamp bolts.

    If tight is good, tighter still, is always better, right??????

    Between folks tightening their hubs on so hard that they pull the helicoil out, to clamps developing cracks at the bolt holes from the same thing, yeah, over tightening is my bet.

    Never seen a failure like that, now I can say I have!

    Glad the guy is okay overall though.....

    Looking at the video I doubt it was anything to do with the course. I would be more inclined to think it was what Mendoncycle said. Again, we have to wait this out. Hopefully the guy comes out of this with no issues.

    Interesting failure. Glad the rider is "OK".

    I have the same fork, weigh about 220 geared-up and have bombed (and crashed) fairly gnarly DH repeatedly with it. Bent a front wheel. Zero indication of damage to the Lefty, though.

    My crazy out of left field BS bogus nonsensical hypothesis:
    Over time, the brake hose rubbed a divot into the Lefty "triple clamp" creating a stress riser that ultimately resulted in the failure.

    More likely - as Mendon said: over-trq'ed the clamps to all hell.

    If someone removed the travel limiting spacers, tire could have jammed into the bottom of the head tube.

    Crazy... I was racing there as well that day. Apparently it was making a minor clicking noise and then gives out....Head impact and then black out. The hills on this course are at best 6' at the highest point. My elevation profile on strava looks like a bunch of little speed bumps. Lots of sand and roots, but nothing that I would think that could cause it to snap apart like that despite how poor of a line one chose. Unfortunately, one of those "1/1,000,000" failures.

    After watching that video... definitely do not feel there was anything significant on the trail that would cause failure.

    I would also be lead to believe that the failure of the part was due to poor negligence of the bike.

    Sorry... should I have first put up several hundred posts before my opinion is of worth?
    Or should my qualifications in metals be questioned?

    I'm not an MTBR pro. I don't have enough posts here to prove that.

    However I have worked with enough metals when I worked with manufacturing and designing of race engine parts. Even through the rigors of mountain biking, the metal isn't subject to extreme tolerances where the aluminum is consistantly being heated and cooled. With forged aluminum, the metal is not heated and cast. It is milled out of raw blocks of aluminum which there would be no air pockets in between the metal. So the only things that would cause forged pieces to fail are excessive stress placed onto the metal itself.

    You have not even examined the item in question. Have you seen detailed photos of it? I'm just interested in why you think the guy hasn't maintained his fork. If you make a remark like that it's fair for people to ask why you have formed that opinion.

    Mendon - as you know I'm not a Lefty kiss-ass like some. Lefty is great. I love mine.

    I don't think lack of maintenance caused the issue. I think lack of appropriate knowledge on how tight the clamp bolts should be caused the issue. Obviously the clamps sheered off. The big question is why. If the clamps were too loose, its immediately noticeable when you try to turn the front wheel. If the clamps waaaaay over torqued, you'd conceivably start making cracks on the opposite side of the clamps. What I can't get my head around is how tight that must've been. In order to break the clamps like that you'd have to tighten the bolts to the point where the entire face of the open end of the clamp is jammed up against the other side. You'd really have to work at it...

    I had two titanium rods with associated screws installed along my spine to stabilize and fix a crushed T6 vertebrae. I'm recovering one day at a time. Cannondale is sending an engineer who is literally on his way to my house as I write this to take pictures of the bike. The medical prognosis is that I should make a complete recovery, albeit with a lifetime of airport metal detector hassles from now on. Not sure if I'll race again, but I will definitely ride again. To answer the question that people seem to have most: The fork just failed. I was in 4th place after getting a decent hole shot in the beginning and was flying along normally and then I woke up on the ground with another rider pouring water on my face. I don't know what happened, but it happened. I didn't torque the shit out of the bolts. I've been racing and riding for years and am not a newbie to any of this. It's just a very unfortunate, and life-altering, catastrophic failure. Metallurgical reports might reveal more about how it might have occurred. I'll post updates when I have any. Thank you to everyone who has shown concern for my well being. The cycling community has been very supportive and so far Cannondale is showing a willingness to accept responsibility and step up with paying medical expenses. I'll certainly keep everyone posted about that aspect of it as well. There are definitely more negotiations about money in the future. My only hope is that they negotiate in good faith. I was doing nothing but riding the bike in the manner for which it was designed. It was professionally maintained as I am a sponsored by my bike shop who is a well-known local Cannondale dealer here in South Florida. Thanks to Jim's Bicycles in Deerfield Beach for all the support over the years.

    I wonder if for your own sake, you should delete the legal obligation stuff towards Cannondale.
    You don't want to disclose info or make assumptions on a message board. It might bite you in the a$$ later on. : )

    So far Cannondale has reached out to me and been very sympathetic and helpful. I'm counting on that trend to continue and I'm hopeful we'll be able to come to an agreeable to everyone settlement without the need for lawyers. Until proven otherwise I expect this to be a possibility. I have nothing negative to say about Cannondale.

    J4m3z,

    3 words for u, my friend: retain a lawyer.

    You need to be very careful about what you say, and be very careful about properly preserving the evidence so that YOUR expert can examine it and opine on the failure.

    Cannondale has lawyers and is acting with the benefit of expert legal advice - u should too if u want an even playing field.

    Wishing u the best of luck with all aspects of this and a speedy recovery.

    I could only echo this sentiment. They put knife to bone and now you have hardware installed?! You're in for a lifetime of potential issues related to your repairs. Maybe not soon, but somewhere down the line. I commend you for not going all gonzo on the lawyer thing but you seriously need some representation on such a serious issue. When you heal from this initial event....it's not over for you. Trust me, I know. Been there, done that, got the avatar.

    Yes, retain a lawyer ASAP. Getting one doesn't mean that you have to sue Cannondale for billions (or even take an adversarial position); it just means that you have someone representing your legal interests. That's why Cannondale has them, right? Their lawyers aren't looking out for YOUR interests at all. Equal footing is imperative when negotiating issues like this.

    If I were you'd I would take down your posts immediately, and then follow the advice of your lawyer until everything is wrapped up.

    Retaining a good law firm is critical, whether or not Cannondale is offering to do the right thing. Long term medical concerns and future expense need to be factored into any type of settlement. Retaining a lawyer does not mean your an aggressive claimant or gold digger. In regards to removing or deleting any or all of the post, don't bother, they're already archived in numerous places and any forensic investigator worth their hourly fee of $300.00 will find them in minutes ( and probably bill out for 3 full hours).
    Good luck and stay the course..

    Before retaining a lawyer, see what is Cannondale is offering.
    At the end of the day, you get pennies on the quarter where the lawyer gets the 24 cents

    I would delete whatever you posted about financial or personal dealing within Cannondale and FB.

    All the best and wishing you the best. I have seen a few bad spills @ getting to the ER. Thankful that it was not a $22k flight to the ER

    It is very easy to crack the crowns of Leftys if the pinch bolts are over tightened. They certainly cannot be tightened as much as the pinch bolts on a traditional stem.

    Best of luck and heal up soon!

    So two things....

    1.) How tight is correct?
    2.) Weren't there some failures with the Cannondale sponsored downhill riders someone around 2k5 or 6? I seem to remember hearing about it then. If anyone remembers that, was the failure in the same part then as well?

    It IS amazing how many shops do not use trq wrenches on various high-end delicate parts. They have some ham-fisted kid reassemble stuff. I got my bike back one time with a grossly over-tightened and busted seat post clamp and crushed carbon post. The shop took care of it, but the level of negligence scared me. I DIY everything now.

    Thanks for the good wishes and advice. I'm not paying a lawyer if it's possible to get this settled amicably. I'm aware of my injury and it's potential problems down the road. I'm no babe in the woods. I'm looking out for me. Don't need a lawyer until I need a lawyer. I'm good natured but not stupid.

    I was a svelt 195. Less now after the accident. I would have a chat with your local Cannondale rep or call them and ask. 275 is pretty hefty but I'm no expert and my situation is certainly not the norm.

    Don't be too concerned really.
    Many, many leftys are in service and get the piss beat out of them and they keep rolling.

    I have seen many brands of forks fail. So, this is not something to only Cannondale.

    All bike parts can fail for one reason or another. I've seen a Trek carbon road frame bottom tube collapse on a lady (maybe 130 lbs). My buddy has a similar Trek carbon road frame and beats it to death and it's more than happy to take it.

    Just make sure ALL you bike parts are properly installed and torqued. If you are not sure how to do it, or you don't have a torque wrench, take it to a shop. Many of us are happy to offer help but your milage may vary.

    My 2010 bike has a carbon lefty. Last year I had a pretty bad crash resulting in my front wheel crossing up and twisting into nearly a 45 degree angle. The bike was thrown 10 feet in the trees. The fork is fine and shows no signs of fatigue or wear.

    My LBS does all of the maintenance on the fork.

    Why would this thread have you concerned? It is anecdotal and devoid of anything to indicate WHY the fork failed.

    If you search MTB Forums, you can likely find anecdotal evidence of failure for EVERY MTB product under the sun. Some things fail from misuse, lack of maintenance, incorrect assembly, defective design, defective manufacture, defective materials, defective fasteners, crash impact, etc. Without knowing the cause of failure, no conclusions can be drawn.

    Lefties are rigorously professionally raced. If the fork crown was defective, you'd see a bunch of failures.

    Well because I just got the bike a week ago and just joined the forum and this is one of the first threads I see.. Initially I was concerned with my weight being an issue on an dual suspension bike to start with, but so far that has not been an issue. I am an athletic 275 BTW not a complete lard ass..lol..The guys you speak of racing these bikes appear to be well under 275lbs, like 100 lbs under..Im sure lefty;s dont fail often, but the way the fork is designed if it does fail, it appears it will be a bad one resulting is some significant injury to the user. What type of poor maintenance can cause failures of the lefty's where they crack off like the one pictured? Not debating just asking what I need to keep inspecting regularly. Also Im sure professional racers get their equipment replaced fairly often from the manufacturers.

    Dajerseyrat,

    I hope I could ease your mind a lil' about the Lefty with this picture. I'm about 255lbs (probably more now) without gear. It's a Lefty Max Carbon 140mm SPV on my 2006 Prophet 4x. Had some issues with the internals due to bad way of transporting my bike, but Mendoncyclesmith sorted that out. Still going strong since...

    [QUOTE=Stumpjumpy;10702666]Interesting failure. Glad the rider is "OK"

    My crazy out of left field BS bogus nonsensical hypothesis:
    Over time, the brake hose rubbed a divot into the Lefty "triple clamp" creating a stress riser that ultimately resulted in the failure.




    Not such a "crazy out of left field" concept. I have seen beginnings of such divots on both of my Lefty lower clamps. I keep a sacrificial material (currently a plastic zip ty) between said clamp and cable.

    Cannondale recommends (they provide the plastic sticky patches) protection of any area where a cable rubs a frame or part, so pay attention to any such area(s) when checking out your bike.
    Forks are for eating, Lefty's are for racing,

    James, please at least speak to a lawyer.
    Below is a link to my Lefty fail in 2006. The top cap unscrewed on a particularly rough course (you cant see that in the vid). I broke my L1, L2 and L3 in this.
    Cannondale Australia wiped their hands of it. In retrospect I should have pursued it.
    This was the first ride on this bike. The Cannondale dealer had one their pre-sale "inspection"- https://www.facebook.com/photo.php?v...type=3&theater

    Outside perspective of someone who barely knows what they are....scares the crap out of me. That one failure would scare me from ever considering one ever.

    Tearing a Lefty down and replacing all internals after every race would never prevent the fork crown from failing. It is not a moving part or "wear" item. It is a piece of aluminum that is either up to the task it was intended for or not. If it were not up to the task, we'd see crown failures ALL THE TIME, as there is nothing a mechanic could do to prevent them.

    It is a SINGLE incident. This fact alone means it is statistically meaningless in terms of liklihood of Lefty crown failure.

    The mechanism of failure is unknown. This fact alone makes the failure meaningless in terms of predicting Lefty crown failure.

    The crown failed on relatively mild terrain. People consistently subject their Lefties to much more extreme abuse FOR YEARS without crown failure.

    Clearly, this crown failure was an anomaly of unknown origin.

    Was it one Lefty out of a million that had defective materials or manufacturing? Maybe. Was it an already crash-damaged or otherwise compromised (over trq'ed) Lefty that was therefore prone to failure? Maybe. The possibilities are many.

    Accordingly, it is impossible to draw any reliable conclusions regarding this event at this time, other than "this Lefty failed".

    You need to stop riding mountain bikes now. I can show you failures of most every fork and component known.

    You must own one or something. Want to know my real feelings? Looks like the dumbest looking fork I could possibly imagine. Of course parts break. But a one legged bike fork? Herp derp...duh. What in the hell could possibly be the advantage? a little weight savings? Or is it the cool factor? Look at my uniqu bike fork....I certainly am super cool for picking this out. How bout a gun without a safety....you could shoot it quicker? Or a aluminum foil car body? One legged fork. Simple math says its a bad idea.

    Tell me to stop riding bikes. Pfft. Why dont you take a bath with a toaster? Not to mention they look retarded.

    You come to this site after being banned from others and add nothing of value to this thread, or this entire site. You admittedly dont even ride a bicycle, laying around on your sofa downing pain killers... So Jayem suggests you stop riding bikes, I suggest you actually start. I give you this advice.. stay in Off Camber where your pathetic useless drivel is welcome.

    You'll notice that your car, (If they have made the mistake of giving you a drivers licence.) has a Lefty and a Righty connected to your front wheels.

    I only care that the guy who got hurt gets better. I could care less what you ride. I had a bad day yesterday and let the poster above get to me.

    Take care Mr. Hurt Rider. I can empathize with you on the back pain. And cars have upper and lower control arms...or other systems that have more than one attachment point.

    Cannondale shipped a brand new 2014 Scalpel Black Inc. which I took possession of this week. A very nice bike. Won't be able to thrash it like it begs for anytime soon, but hopefully someday. My back is still healing and there is still plenty of pain almost 3 months out now, but the doc says it looks good so far and is hopeful for a full recovery and I should be able to race again if everything heals up properly. I'll know in about a year. It's a long healing process. Cannondale is meeting with me in late January/early February with a mediator to hammer out the final settlement details. I'll be damned if I'm going to give a lawyer a single penny of money that I deserve. They didn't break their back, I did. If we can come to an agreeable settlement like grown ups then that is how I would prefer it. If I feel for one second that I'm being taken for a fool then the process stops and the court proceedings begin. Cannondale has understood this from teh beginning and has been helpful and agreeable during the process so far. They have covered a small insurance deductible without even being asked and provided me their top-of-the-line XC racer and allowed me to keep my previous bike, which besides the fork is perfectly fine, and I also did not ask for this. They told me to walk into my bike shop and tell them to order any bike that Cannondale makes as a replacement. I have not signed any paperwork other than medical consent forms so Cannondale can collect all the medical bills related to the accident. I must say that if Cannondale is indeed going to try and screw me over they are being very generous until the other shoe drops. I will take a few sheckels less in settlement cash (after medical expenses are paid) if that means we get this resolved quickly and without a lawyer getting a dime. So far I can only say thank you Cannondale, except of course for the whole Lefty brace failure part...that part sucked and changed my life.

    j4m3z,

    I hope you have a full recovery and soon are on-board of arguably the finest XC bike on the planet.

    I happen to agree with you and think your handling the situation with class. Why get aggressive until you have good cause. Give Cannondale a chance to handle this with integrity and keep there first class reputation.

    And keep your positive additude , you'll be back on the saddle soon after your full recovery enjoying something you love.

    Cannondale has lawyers on retainer. They are being paid regardless of this incident. To the OP, best of luck to you in your recovery and be sure to stick to your physical therapy regime!

    I have the Alloy Lefty Max from 2007, have it serviced by Cannondale about every year and they upgrade all the internal components for me and it costs about $250. It was originally an XC fork, then I broke my DH fork and threw it on for the weekend. I was scared something would give with all that pressure, but I still have no 'failure' content to share about. Those alloys are a brick.

    Quit trying to minimize it, it was a new bike when it happened, and if you want to take that kind of risk then you are more than welcome to!

    Just trying to protect the public. Listen, I know some of you make a living selling and repairing this product and want to protect your livelyhood. I can understand that for sure. However, I make a living assisting with brain and spine surgery and would not recommend this product to protect my livelyhood. That wouldn't be the right thing to do.

    Better off screaming in public forums about the dangers of cigarette smoking, high fructose corn syrup or meth, they hurt way more people than bike products.

    Indeed. Hard to know what happened based on a single photo. But I'm guessing that someone didn't properly tighten a couple of bolts. Nothing special about that--loose bolts lead to failures of all sorts.

    To suggest that an entire line of forks is "unsafe" due to a couple of poorly documented anecdotal failures is a bit much.

    Here's my response to your PM, in which you claim that Cannondale's forks have been recalled (and therefore that the design is inherently dangerous):

    The 2007 recall was the result of a batch of forks being assembled incorrectly. There were 15 resulting injuries reported to Cannondale. There was no indication that the actual design for the fork was faulty, or that subsequent years suffered from a similar manufacturing fault.

    If you Google RockShox recalls, you will find similar instances of failures.

    The truth is that all bike parts can have issues, especially if they are improperly serviced. But there is no evidence that Cannondale's Lefty is somehow worse than the other forks out there.

    I'll add that I've seen this before too. Happens when a fork is neglected. As per the owners manual, the forks should be seen by an authorized service center frequently, like, once a year, or after a certain number of hours ride time.

    Specifics aren't important, as they have changed the recommended time frames over the years as models change.

    So, if you ride the crap out of your bike, thoroughly abusing it, never getting it serviced, in full ignorance of the maintenance schedule provided by the manufacturer, said manufacturer is supposed to totally redesign their product, as well as pay for damages incurred by the end, negligent, lazy, cheapskate user?

    If that's the world we're getting to, stop the world, I want to get off......

    The agreed consensus is that cable rub on the bottom fork bracket could have led to failure of the fork bracket and subsequent failure of the top bracket when sufficient G forces were applies as I descended the hill that preceded the failure of the fork brackets. There was evidence of cable rub that was not clearly evident except under closer scrutiny on the underside of the lower fork brace attached to the head tube. Cannondale and I have reached an agreement and they have acted very responsibly and are investigating how this might have happened and will make every effort to avoid any type of similar tragedy from occurring again. I'm still riding a Lefty Scalpel - a new one of course - and am making sure that my cables are not rubbing on any crucial components and have painstakingly applies the clear plastic rub decals to any areas that might be subjected to cable rub. I encourage every mountain biker riding any bike to inspect where their cables are rubbing on their components/frames and make sure that the wear doesn't compromise the fork components or any other aspects of the integrity of the frame or forks. This will be my last post in this thread. I still ride Cannondale MTBs and road bikes and can say that Cannondale was extremely cooperative in resolving this unfortunate incident expeditiously and agreeably without the need for money-grubbing lawyers. We came to the table and worked out an agreement without ever stepping foot inside a courtroom and that alone is worth riding a Cannondale. Thanks to the Cannondale folks who contacted me immediately after the accident and who worked with me through the entire process and worked to get this resolved quickly and amicably. Cannondale, despite what some might think, did not make me "rich", but I would recommend their products to anyone as I believe they truly wish to make the best bikes available, and I own 4 of them. This is not a "paid endorsement" no matter what any haters might think. I'm just a guy who had an unfortunate life-altering accident and the company that provided the equipment I was riding stepped up and resolved the issue responsibly and with the proper adult attitude. Mine was an unfortunate freak accident and I don't think that it's an inherent problem with the Lefty. You just need to make sure your cables aren't rubbing on the fork brackets. This probably isn't an issue with 99% of the bikes. Just keep an eye on where your cables run.

    This is exactly the type of attitude that has me questioning if my next bike will have a lefty. Basically calling customers names because they ride their bikes and want them to work. Since when is riding your bike thoroughly abusing it? Since when is owning a product that likely cost 2K ++++++++ cheap? Since when is riding the "crap" out of you bike lazy?

    I understand that leftys require annual service and its no secret they are less user serviceable then other forks. But the attitude is unnecccesary

    abusing a bike isnt when you ride it hard, its when you ride it hard and ignore required maintenance.... the attitude doesnt bother me, but then again, I do required and constant maintenance...

    No attitude, just a long earned understanding of certain types of riders.

    Those who understand they bought a high tech product, and that this type of equipment requires routine service, adjustment, etc, in order to work well, and as it should.

    Then there's those that feel that since they spent a bunch of cash, they should be able to ride into the sunset and not ever think about their equipment.

    Those types will likely cry lawyer or warranty (as well as insist they were JRA) when something goes wrong too....

    Drive the car, never change the oil, change the timing belt or rotate the tires because it's a $40K car? Yeah, that won't end well either.

    Not saying you will do any of those things if you buy a new bike (or that it's how you treat your current one), but spend enough time working in the industry, and you'll say the same thing.

    Edit/addendum: as I think about this more, I realize I need to clarify something. If you want to ride your stuff hard, put it away wet, do no scheduled work due to whatever factor you choose, that's fine. But walk in to a shop with your arm in a sling and bandages on your face, with a damn smile on your face, saying something to the effect of, "well, at least I got my money's worth before it broke".

    Those lawyering up in this situation is the group I referred to earlier as lazy, cheap, etc etc etc.....

    The 2007 recall was the result of a batch of forks being assembled incorrectly. There were 15 resulting injuries reported to Cannondale.

    The problem is this was 2009 and it was still defective, bet you are glad you didn't get the bad "Batch" could have been your last ride.

    I haven't seen any evidence that there was a "bad batch" in 2009. If there were a systemic problem, it would likely would have been exposed and addressed by now.

    Please stop spreading unsubstantiated FUD.

    Getting ready to put my lefty on new 2014 Pivot Mach 429 carbon. I have no fear using my lefty on this bike, either does Shirk's the shop I orderd the Pivot from. I highly respect this shop along with MendonCycleSmith.

    I think its funny how certain people fear what they don't understand!! Just go away, please !!

    No word for three weeks and then some disjointed response to the basically empty theater?

    You've obviously never heard the numbers from car manufacturers on the number of recalled vehicles that don't get brought to dealers for the required work.

    Just because something needs dealer attention, doesn't mean it will get it.

    Not like GM is showing up at your door and picking up your defective ignition switch laden Chevy Impala to do the work....

    You have to know about it, and then actually care enough to get off your lazy, fat American butt and take care of it.

    How many un-repaired Leftys sit in garages to date, we may never know, but it's not the tax payers responsibility, nor Cannondales, to pay for every time someone gets a boo boo from something that never even got factory recommended service done at proper intervals, let alone, had a simple recall fix taken care of.

    Yes, please, just go away, you offer no useful, coherent help at all, and I doubt very much the ambulance chasing lawyer you're working for would be happy with you speaking about a lawsuit you're part of, on a social media site....

    The 45 rotated Rize lefty on the picture has nothing to do with "properly torqued" bolts though...as one can clearly see on the image it's a bonded carbon lefty and the top structure is still properly aligned....it appears as only the lower got rotated somehow, which indicates busted needle bearings or something. This can happen if no bearing reset was done, damaging the needle bearing cages which are actually also keeping the square lower from rotating besides keeping things frictionless.
    Or the needle bearing races slipped out of their locations due to a lose cartridge....but I second the notion that these are rather uncommon occurring instances.....I still ride my 2007 Carbon Lefty Max on my Prophet with a new PBR upgrade and I never had any issues with it...Matter of fact I prefer it over the Hybrid Lefty as it is so friggin smooth!

    Third major incident with a bike, I think he should cut his loses and just sell both of them and walk for exercise. None were his fault, but I feel he is being told something here...
