    Dude you’re like a BMX scientist... and with a natural born teaching ability that’s miles ahead of the other youtubers who let their online personality get in the way of the information.
    In the 80s we literally hammered thin metal slivers into our seat clamps and secured loose and stripped brakes to the frame with wire before each ride, the session lasted as long as the wire did haha! Pedals back then had cotter pins in them, if it took too many hits you’d end up with a slightly floppy pedal on one side .... (its no wonder I was so shit) - things have come a long way.

    longer stem = more stability but slower barspins/whips. harder to get into nose mannies but easier to hold em, shorter stem = more twitchy but faster barspins/whips, easier to get into nose mannies but bit harder to hold

    If you know the reach and rise of a stem, you can use the Pythagorean theorem to calculate the extension.
    (Reach x Reach) + (Rise x Rise) = (Extension x Extension)

      It puts your bars higher up which can help with back strain and give a different feel to riding. Whether or not it is good is up to the person riding

  • @yvandupapier
    @yvandupapier 5 лет назад +2

    It would have been great to say that having a stem with a recessed cut out increase the rise of the stem, cause it will need and additional spacer to keep it to the same : (ex : fiend morrow V1 vs V2)

    • @bmxriderforlife1234
      @bmxriderforlife1234 5 лет назад

      also worth noting make sure your fork compression cap clears the recessed out area, my buddy had an issue where he had to file his down a lil to get it to fit.

    Also, I often hear that people would either change they bars for a 0.25" lower, or switch to a frond load. But they don't realise how lower a front load stem will keep their bars compare to a 0.25" lower bars. There might be more than 1" of difference. Anyway, I love frontload stem.

    Hey man, great video, but I have one question - You say that the rise of the stem is measured from the center of the steering bore to the center of the handlebar clamp, in a different video a guy said to measure the rise starting from the Very bottom of the steering bore of the stem.
    This has confused me a lot, because using your method here my Front load stem rise will end up in the negatives, but measured from the very bottom of the steering bore of the stem it will be about 7mm, which is what sourcebmx is telling me the rise of my stem is. So I'm just curious if you could inform me on which is the correct way or whatever is going on here.
    Thanks heaps

    • @Brant_Moore
      @Brant_Moore  4 года назад

      Apparently my video is incorrect. Looking into things, the resources I used for that piece of information were incorrect as well. All bmx stems I can see appear to be measured from bottom of stem to center of handlebar clamp.
      I can’t believe it took this long to figure it out

    • @Brant_Moore
      @Brant_Moore  4 года назад

      The weird thing is that it appears some stems are measured the way outlined in this video. How confusing. Practically though, there’s no reason to need to measure for yourself and not trust the info bmx companies are giving unless there is zero spec information from them

    So ummm. Rise is measured from the bottom of the stem to a horizontal line through the middle of the bars. Not from the middle of the stem. Please put out a video or mention this as you're misinforming a lot of viewers here.
