    Well, I was riding and I was moving along pretty well. I will say that I don't baby the bike and I know that everything breaks, I am just bummed I won't be able to ride it for a little while. Rode a pretty technical downhill in Durango when I heard a little ping and the front end got a little squirmy. No crash luckily. I'll get in touch with steve and see what he says. I am just worried the replacement will be beefier and it won't ride as well. It really was a great riding fork, may she rest in pieces.

    That's heartbreaking... (disc brake sh!t talk goes here).

    Hope you get up and running again ASAP.

    I know, it's only 3 years old but no other forum knows what it is.

    That is sad...at least it died with its boots on.


    Better broken riding, than hanging on a wall.


    Glad you didn't get hurt...could have been bad.

    Good thing you're ok, hopefully you get bumped to the front of the line for a fork.

    Sorry to hear about the fork failure. Never a good thing!

    I don't know where it actually originated but the inside corner of the upper mount on the disk tab was the only place that was still together when I noticed it. That quickly separated when I grabbed the front brake and rocked just a little

    This was when I first noticed it, cracked about 7/8ths the way around. Pretty clean break, very little deformation on the metal. Also break is about 1/4 inch above the upper mount.

    Well, it took steve about two hours to respond to my email. If sarcasm translated well to the forum I would have something sarcastic to say. Let's just say I am super impressed, once again.

    I guess frontal impacts would cause elongation of the front of the fork leg and compression on the back. So the crack should appear on the front first. But I think the bending of the fork leg is being concentrated at the end of the disc tab.

    Steve worked with John Castellano to come up with a design that distributed the disc load over a long distance, but it may have had unintended consequences.

    Sorry man.
    Suspension adjusted? Are the legs butted? Did you ever use the low rider mounts?
    Zip ties? Not on my bike!

    Want:
    650B rims or wheel set. 80's vintage 32 or 36 x 135mm

    Non-suspension adjusted. I don't know if the legs are butted or not, but it does ride incredibly well. I have mounted a rack up but haven't actually put them to use yet. Steve put rack mounts on the frame as well, plan on using them eventually.

    Not as bad as a carbon failure, I didn't face plant and stick a carbon tube through my spleen!! When I noticed it it still wasn't separated. I think a lot of people would get turned off by seeing a fork like this but the people who are looking to get a Type II probably have been riding long enough to know that everything breaks, no matter the quality of the product. Steve says it can be repaired, I trust him.

    Even if I have to pay full price for another fork, still well worth it.

    Easily repairable as he can just sweat out that leg and replace it with another.

    Very curious break however.

    Pfffft, been done before. The Kastan UniBlade fork, predates the Lefty by about 14 years.

    1989 Kastan KEX Pro 24 - BMXmuseum.com

    Thing is, I've seen as many run on the left as I have the right.

    That's why I was thinking a through axle may be the ticket

    Just tighten the quick release *really* hard. Should be fine.

    I don't know about that. I get on the "all mountain" forums I KNOW that won't work!!! The coefficient of the thingamabob pretty much dictates that all 9mm qrs fail. I have gotten very learn-ed with all the talk about how you have to ride with at least a 15qr and a tapered fork on anything but a bike path. You vintage guys don't know anything😁

    Yeah. Even the CX guys are crying for through axle, tapered, carbon forks.

    Bummer!! Hope Steve gets a fix for the issue and gets you a new fork.

    And as others have said, I'm glad you weren't hurt. That could have been ugly.
    Each bicycle owned exponentially increases the probability that none is working correctly.

    Don't bring that trash talkin' here, because you're bigtime wrong. The thingamabob coefficient only comes into play with a 27.5" or 29er wheel with a 180mm rotor or bigger because the tangential leverage ratio exceeds the proper force vector and causes the dropout to fail, or in your case, the fork to give up.

    That fork is clearly made for awesomeness, not eXtreem awesomeness. Gees!

    Crap, I forgot to take wheel size into consideration. Back to the forums for me I guess.

    Well, this is the perfect time for me to get the frame painted as well. I know, it won't be functional but it will look nice. I am thinking Maroon/Cream. Unless anyone else has a better idea. Maybe I will start a new thread.

    And if I am going to do that I had better get a stem to match so I sent out an email to Joel at Clockwork Bikes for an LD. Time to try Dirt-Drops again. It has been a long time.

    That's right. And we call it a thru axle. Though axles are so last year. kinda makes me cringe when I see "thru" though. I'd like a thorough discussion on this topic.

    If you're going custom on the stem, make sure you know your measurements. A bunch of spacers is kinda odd paired with a custom stem.

    That's just crazy talk. We all know fit is just based on looks.

    Case in point:



    If you have access to a fit finder you can avoid this.

    For anyone who has a disc fork like this, try pinging the left and right blades with your fingernail. The side without the disc mount rings like a bell, while the side with the disc mount is a dull thud. That disc mount radically changes the compliance of the blade.

    It seems to me that almost all of the suspension loading stress (and braking stress) will be borne by the stiffer blade with the disc mount. At best, the design of the disc adapter can distribute the stress along the single blade, but from looking at this failure mode, even that looks doubtful.

    So I don't think a thru axle would help much at all. Might as well be a lefty, I mean righty (lol CS2)

    And she is almost back up and running. Steve was great to work with as was Joel at clockwork. Looking forward to getting it back up and running. Super stoked!!
