    Lauf TR29 fork

    Wonder what tire sizes you could squeeze into this fork? Or are they planning a fat tire version?

    990 GRAMS !!! Amazing.

    I laughed so hard when I saw this the first time. I'd had ideas before about leaf spring / no maintenance / low maintenance forks (low would include a damper) but figured no one would want one.

    These people are my kind of crazy.

    Certainly a polarizing design.

    The version I have in my head would resemble a love child between a Lawill Leader and a Jones fork, with the front truss of the latter acting as the leaf.

    It's not a new idea! But is packaged and made available in a modern way. I love to see this kind of stuff.

    Cool, but what does it have to do with a fatbike?

    Re: Lauf TR29 fork

    Funny Drew... I was just going to send you a message today on MORC about that fork and how you should make a fat version.

    Rode some trails today that are hardened up former mud with deep horse tracks all over. It was like riding on rail ties... got me thinking maybe I doooo need a suspension fork. But the Moony is heavy enough already. A light carbon leaf fork would be the ticket.

    Here's a pics of the whole thing:


    Doesn't look wide enough for a fat tire, or mod-able, so you would have to wait for a fat version.

    Might fit a 29+? Cool design anyways.

    Alt bikes with Alt bars going for Alt forks - go figure.
    If I did not weigh 230 lbs - I would have that on my 29er in a second! (oh - if I could even think about spending that much money on a fork).

    I have always wanted to take apart a girvin fork and drop some spacers in for a fat bike. Like the black sheep fork at the hand made bicycle show...

    The former Cervelo Lead Engineer, Gerard Vroomen designed that fork. It looks scary to me...

    This fork has it's own thread over on the 29er forum, where it seems to be almost universally panned, especially by those who have never even tried it. In a nutshell, you must either be an idiot or a dolt if you think this fork might possibly be something worth trying. I can't figure out which I am.....

    I simply don't like the idea of joining two VERY DISSIMILAR materials together...

    I'm not sure how it's done on this fork, but on other trailing link forks you can set brake linkages to minimise dive. The big advantage of that is you don't need as much travel in the fork.

    2.35" tires - 487A/C - 180+ rotors.

    With just 60mm of travel , wonder why the high A/C?

    If this sub forum gives a better reception to the idea than over on the 29er, maybe...they could be persuaded?
    Just like Fat Bikes...the posters on here can go anywhere...and do.

    Carbon, and what's the second material? I think I remember reading the leaves themselves are glass composite. If that is really the case, glass is an insulator, I wouldn't sweat that part.

    We need dampening and I do not see how this fork would give us that... also how do you tune it for different weights etc...

    You've got far more experience than me in this. Is done with geometry or stiffness of the links? Combination of both?

    Wow, terrible review, rode it around on the grass and then compared it to a long travel fork at the end...?

    My impression was it was being compared to a rigid fork.

    The thing most rigid fork users don't like about suspension is brake dive and the weight of a suspension fork.

    From the test I gathered that it didn't pogo up and down, so that's good.

    It does seem to dive, but with limited movement. Not a tragedy, but still avoidable if they used a brake linkage. Brake dive would put me off it rather than any other factor.

    It would make more sense as a fatbike fork because we don't need a huge amount of suspension IMO.

    As has been pointed out, the limited movement can be achieved by modifying a telescopic fork with possibly a weight reduction.

    The lack of moving wearing parts is a plus and no maintenance. I've owned suspension forks that are supposed to be serviced after every 17 hours of use, which strikes me as next to useless.

    It's the sort of fork I'd stick on a 29er if I was using it for long rides on stoney surfaces.
