  1. Nice pics Skypie.

     

    Sheriff, went and found a link to your Flickr account...

     

    Dude, you know your way around a lens!!! This bike milarky is for the birds... just a pitty SAFA's don't like paying for photos...

     

    Huge Kudos mate!!

    If you wanna see what the sheriff is good at, go check this out.

    Agreed, you have a good eye and keeping it simple is awesome.

    I was once told, "it's about the negative spaces make the subject more interesting"

     

    If I may, both your pics have, what can be called, distractions.

     

    The beach photo has excellent everything, but the beach should either be almost complete, maybe ending near the bottom right, or none at all. I think that would just leave it open enough...

    The bikes, that front wheel, I don't believe it should be cut off...

     

    Both images have a, just quite not right feeling.

     

    Remember, you can crop out, but never paint in...

     

    But I like your work

  3. Happily, and I am very happy, I bought a Shova from a mate.

    I know it has been well looked after and has very good components. It has been regularly serviced by reputable bike shops.

     

    I am very happy with the Bomber fork, and when I got it, it was set in the lock-out position, when I asked him about it, he actually didn't know it had any other settings... it has recently been serviced and feels very good.

     

    However, there is a problem with the rear shock.

    It is a Manitou Swinger - 3 Way.

    The bike does ride with the weight to a rear wheel bias, and only when you are out of the saddle does the front shock travel increase. So I guess the rear shock has worked hard.

    Again it was recently serviced.

    Here the issues

    1. Leaking Oil - there are drips of oil on the frame below the shock after every ride, and I caught a drop about to fall, at the end of my last ride.

    2. The rebound seems to be dropping pressure. No matter what I pump it to, the next time I check it, it is back to 45 psi. The manual says I can take it as high as 90, but I have changed it a little and a lot, but always says 45, when I put the pump back on it.

    3. It is making a noise on harder hits, not a hard banging noise, just a sound of the air going through the shock.

     

    So here my questions.

    Please help.

     

    1. Is there another thread on the forum about this?

    2. Should I get it looked at by a different shop?

    3. Do I scrap it and get a new shock?

    4. If so, which one?

     

    I like the Monarch, size would be 200/50, and does that fit the Shova?

     

    Taa, in advance.

  4. Are you sold on the brain because you don't want to reach down and slam on the propedal for long climbs or gravel grinds?

    Hairy one, got a mate who's riding that computerised scooter, runs like a quad core outside processor, huge amounts of rim.

     

    He recons it's the smoothest ride he ever had. Cleaver enough to know when you're peddling, decending, climbing, etc... And can recognise the combinations, opens and closes the shock and fork to the appropriate amounts...

     

    Not that I want to ride a lap top, but does sound pretty cool.

     

    And I suppose, in 10 years, non-computerised bikes will be old school.

  5.  

    Think Pythagoras theorem

     

    If you increase the width of the bars it increases the overall length to which the force is applied thus increasing the moment for the same force.

    If you decrease the length of the stem it decreases the overall length to which the force is applied thus decreasing the moment for the same force.

     

    *one can go more into it and take the angle to which the force is applied as an additional factor.

    Ja, if you widen the bars, I think I get that.

     

    So let's say we have 500 wide bars, what happens with a 50 stem, 100 and 200?

  6. I left that part out because rotational inertia complicates things a bit BUT in this case the moment caused by the rotational inertia of the bar is negligible because one can assume that the bar does not have an angular acceleration about the steerer tube.

     

    That being said, it will have a constant angular velocity when turning the bar. So as a result you will have to move your hands further in comparison to a shorter bar. But this additional movement is one of the contributing factors in having more precise control over the front wheel/bike with a wider bar.

     

    EDIT: grammar.

     

    In like simple inglish, can one like to try to explain what a shorter stem / longer stem does to the physics...

     

    Seriously, I get what the bar width vs stem length does to the ride position, but with out that in mind.

     

    The longer the stem, the wider the arc, the less energy the moment of inertia requires, right? So then the short, the more energy? Less twitchy?

     

    (I think I need a pen and paper...)

  7. similar to, but very diffferent.

     

    Front triangle is very similar. But it's a newer age bike, and there's only a limited amount of ways you can shape tubing.

     

    As for the rear - the primary pivot point on the Pyga is higher, the top rocker is smaller and the rear pivots above and in front of the rear axle.

     

    The Trek's rear pivot is ON the axle, and the top rocker is longer, creating a different leverage ratio.

     

    similar to, but vastly different.

    Thank you, do you know who did that shock connected to the rear swing arm first?

    For want of better terms...
