    The rake, trail, and offset destabilizes rotation for flatland tricks. It would nice to find a geometry where flatland can be done with a bike still somewhat capable of other styles of riding.

    How do you think this effects fakies? I feel like I notice instability the most during fast fakies and fakie carves. Do you think trail still stabilizes and self straightens during a fakie or does it flip and do the opposite because the motion is backwards? If it does the opposite maybe a steep fork would give a smoother fakie with a added benefit of a tighter carve. Thoughts?

    Very interesting. I’m thinking of getting a WTP Reason 2021, and I was wondering if its apparently extreme geometry would make it a bad choice for a beginner, what do you think? It has a 76 degrees HTA and 15mm fork offset.

    • @Brant_Moore
      @Brant_Moore  4 года назад +3

      When you’re first learning you haven’t developed a sense of what you like yet or what tricks you’ll do, so most likely you’ll just ride it no problem and learn just as well as on any other geometry.
      Then once you start to learn some tricks and get better you’ll slowly start to figure out what geometry you like and that’s when you start changing things or even realize that you want to keep it the same

      I would highly doubt it would work without some heavy modification of the hub shell.

      This is the harsh reality of box you get what you pay for instead of trying to make something into something that was not made to be that way. I am a old man in a young men's sport but have seen a lot of changes in bmx over the 2 decades I have been in this bmx life. Get this Huffy bikes made a strong come back and everyone wanted one the TL88 Todd Lyons signature frame. Unfortunately most of you don't have any clue who this bmx savage is. Bmx in the late 90s early 2000. I feel was the best time and it was lit. Dan's competition 199$ got you frame and FORKS didn't matter the company. Getting a S in m homes with pitchforks for $200 and it actually cost more if you wanted the frame painted it was more or less Chrome all the time some people in Hamel know what I'm talking about but I don't know guys all you young uns the other future BMX don't let us old saltdogs down

    This is pretty much a fool-proof guide to understanding the relation between the headtube angle and the fork's offset. If someone doesn't get it, it's because they don't want to get it. Call me weird but my headtube at 76.5° and my fork being an odyssey r15 makes for a beautifully twitchy and squirrely steer

I was told by a very good source that no FORKS are dead on point there is always a little off by like maybe 2 hairs

    i went from a 35mm offset fork to a R32 fork, and i drastically felt the difference, it was way more twitchy (then i switched from a 20.8 frame to a 21 so this balanced the things). Still, after seeing this video i don't understand well why on the internet everyone says that in mountain bikes a longer offset is less stable.......

  • @_0v.r
    @_0v.r 6 лет назад

    There's a flaw with this. This is all based on the bike staying still, and perpendicular to the ground, and doesn't take leaning into a turn into consideration. If you ride in a straight line, and turn your bars 45°, the lack of trail on short offset/steep ha is more likely to force your bars to 90°, sending you otb. You almost always lean into a turn. The best way to really feel that difference is when trying to fakie slider. With more trail your bike will want to turn, less trail the front wheel is more likely to slide.
