    Trail numbers ...???

    I have been reading up lately on geometry again, focusing on trail.

    Is there a a range of numbers for a certain bikes. By this I mean do XC 29 bikes have a certain range versus downhill rigs.

    Really looking for a link to chart with ranges that states for example, 80 or higher is considered a high trail number and will lead to a stable handling. Or on the otherhand, a 70 or lower is considered a low trail number that will lead the bike that feels unstable.
    You cannot go against nature, because when you do, its part of nature too.

    I think it's a combo of things like HA, TT, chainstay and wheelbase. Unless you are riding a Genesis geometry fork, not much you can do to change just trail number on your current bike. As for custom, well it had never came up when I discussed handling, things that I mentioned above came up quite a bit. It could be the "secret sauce" builder don't usually talk about.

    If I understand it correctly, you can switch the offset of your fork, by switching fork, and in turn change your "mechanical trail". Old WB forks had a 39mm offset, Reba's and Fox have a 44mm or 46mm and G2 forks have a 51mm.

    You could also get one of those Angleset headsets. So there is alot of changes that can be done.

    I can't seem to find a chart that states 80-89 makes for a very stable ...etc.

    I also get that it is part of the equation, not the entire equation...

    I made a android app to calculate trail. I started a thread in frame building about it.
