This might be a stupid question but, what difference does adjusting the geometry on an Specialized SX trail make? I'm running it on high at the moment.

    have you looked at the manual? it says in there!

    No mention, I was wondering what difference it would make to the ride and handling.

    Thanks but not what I'm asking, I'm wondering what difference it will make to the handling.

    well a slacker head angle = slower handling.

    and a lower BB more stable.

    Believe it or not it makes loads of difference riding with the different shuttles. For general riding trails & not too agressive freeride use the high setting but it will take anything you throw at it, it'll just feel a bit unstable on occasions. When you're mainly riding steep descents & proper freeriding put the lower one on.
    I forgot to change mine on a Wharncliffe downhill run & regretted it as it felt like I was going to get thrown over the bars all the way down. Luckily it was in my back pack & only took a couple of minutes to change.
    Hope this helps dude & top choice of bike.
    Anyone can be fashionable but you're born with style!

    I agree with Clarkson and Steve.

    I've got a Specialized Bighit for downhilling which has rear travel and bottom bracket height options. I think these would also effect head angle. It feels tonnes better set at the lower bb height. My weight seems to compress the bike and fork, rather than send me over the bars. On the odd occasion that I'm riding a course where I repeatedly hit the chain device I'll raise the bb height but then the bike doesn't feel as nice to ride. I'm too lazy / not confident enough to mess about with the shock. I like it how it is.
