    But??

    which are in front of the steerer-axis

    Its actually hehind the steerer-axis...

    inelegant design solution to introduce a lateral force

    Is didnt need any introduction, it was already there. Your bike even haz it :), and you make use of it with every turn you take. It makes your bike take turns in a comfortable way.

    More importantly I don't think you can prove that you have perfectly achieved it because riders are so good at subconsciously compensating for lateral forces.

    I dont see what these two have to do with each other.. You saying Ive been kidding myself all this time?

    As @mdcc_tester said, it's really a question of whether you can do it well enough for riders not to notice, not whether it will ever be perfect.

    True!

    Your comment suggests that setting up needs to be done fairly precisely with regard to canting vs. offset.

    I guess Im just a perfectionist... you may hold that against me any time

    If you change tyre size, the wheel radius will change, which will change the offset, so the canting will then presumably need to be changed if you want to precisely match the opposing forces.

    But not that much of a perfectionist..

    Camber force is also affected by loads of things including load and tyre pressure, so if these change the camber force will change. Will the counteracting force change in proportion for the handling to remain truly neutral, rather than just good enough?

    This depends on how picky you actually are (I mean the rider.. not you personally) If you'd change the wheel diameter with lets say 5 or 10 mm, you'd need to adjust the lateral with... oh maybe as much as 0.01 mm... I need to think about that...

    There is another effect much more obvious to the rider in the difference in taking left and right turns ... It responds in a different (noticeable) way

    however, you are doing yourself no favours with this kind of phrasing...

    More importantly I don't think you can prove

    You sport the same kind of phrasing the Pope was using in reference to Galileo, I guess Im just not into your type of church but suit yourself..

  • Its actually hehind the steerer-axis...

    The fork-ends are in front of the steerer axis (although the contact patch is behind). Presumably if a leftward force is exterted on the fork-ends by the hub, then doesn't that translate into a leftward turning force?

    Is didnt need any introduction, it was already there. Your bike even haz it :) [a lateral force], and you make use of it with every turn you take. It makes your bike take turns in a comfortable way.

    ...but it's not there when a forked bike is travelling in a straight line, because the wheels are vertical. That's my whole point: you've introduced a lateral force even if the bike is travelling in a straight line, and you only create a genuinely neutral-handling bike if you exactly counteract it with a precisely matched counter-steering force. That additional requirement for the precise matching of forces is a really inelegant.

    I dont see what these two have to do with each other.. You saying Ive been kidding myself all this time?

    Of course they have something to do with each other, the only reason you can get away with the inherent problem of your design (as laid out above) is that riders are very good at subconsciously correcting for spurious lateral forces; their bike-handling skills (which have been practised so much as to become subconscious, automatic systems) deal with the bike's imperfections without letting your conscious self know about it, so they are fooling you.

    There is another effect much more obvious to the rider in the difference in taking left and right turns ... It responds in a different (noticeable) way

    Ok, so that's a more substantial problem!

    Anyway, I'm guessing there's a healthy degree of daftness/trolling in this whole proposition, so I'm not going to get involved much more. I'm glad to have learned something new from this ridiculous bit of tinkering in any case.

  • (although the contact patch is behind).

    And its this patch the forces are exerted on, translating into a right turning force. Maybe Ed or Tester can explain it better then I do

    ...but it's not there when a forked bike is travelling in a straight line, because the wheels are vertical.

    True, although theoretically there is hardly a second where a bike actually IS going in a straight line, still theoretically true

    That additional requirement for the precise matching of forces is a really inelegant.

    I totally agree with that.

    I guess the whole point of my project has had a different objective. (it may even be called recalcitrant)

    From the traditional perspective: The introduction of the off-trail torque matching sure is inelegant. Id go as far as calling it plain ugly!

    From a construction perspective: The traditional fork can bee seen as inelegant... (when you compare it to a straight tube)

    I appreciate both perspectives

    is that riders are very good at subconsciously correcting for spurious lateral forces

    Ok, so that's a more substantial problem!

    Then following your first argument that problem is solved. I will admit it is a side effect that still annoys me and I havnt found a way around it (there probably isnt anyway)

    Exactly my point.. It was an (silly)attempt by me to move discussion beyond your Yes/No argument and appreciate different perspectives

    have learned something new from this

    Thats nice, whatever it is that youve learned.. learning new stuff is nice it is
