    Ever heard of a thing known as an educated guess? :roll: assuming the bike is stock, it will probably have quite a long stem, which it does and relatively narrow bars, which it also does. Therefore a small setup change, say to a 70mm stem and 710mm bar would make a big difference to the bikes handling and offer the OP more control than his current setup and thanks to the shorter stem, faster steering.


    Not if he's wobbling round the berm like it's shaped like a fifty pence piece in the first place.

    short stem/wide bars aren't just a bikeradar/future publishing mantra, MBR is well into that too.

    get your knee out and lean....I learnt at Fod the best. lean until you find as far as your tyres can go and then fall off and don't go that far again......well that's how I did it anyway :lol:

    I do find reading the thread rather than guessing - however 'educated' (Educating by reading the thread would be a great idea) works really well!

    Would add to that though that a 90mm stem with a 690mm bar is a bit long, I'd normally look at that being paired with a 60/70mm stem.

    +1,

    I find best place for me for berms is the 4x at chicksands, the berms there are about 6 foot!

    Don't know about you, but when you do lean a bit too far, and the bike skips out underneath you - I always end up laughing. It might be because it's a slow, and not a particularly painfull way to fall - or I could just be mad.

    Not necessarily needed for berms, but the technique will help you rail berms as well as flat corners

    Wider bars/shorter stems/slacker/steeper angles will not make up for lack of skill

    +1 also have a look at :

    Wow guys :shock: Thanks for ALL your wonderful knowledge and really useful info :lol:
    I think the first thing I should do is run the blue route more, and try to adjust my lines & technique.
    If I find I'm still struggling I'll then look into the tyre/bar/stem debate :)

    If you're going to Swinley keep an eye on London Calling in rides, or the Facebook page in my sig. I'm rubbish but some of the people I ride with actually can.

    Cannot defy the laws of physics.

    All this 2 different tyres baffles me as yes, 1 front biggy may provide more grip and thinner on back for more speed or what ever. But is it not better to have two tyres working in harmony rather than against each other?

    Just a thought

    why would they be working against each other?

    Nope. Keep practising by riding more.

    Id be willing to bet money that changing your stem makes approximately 0.000001% difference to your cornering if you haven't nailed the technique

    Which is wh we all still ride round with 150mm stems and 500mm bars... You can't seriously be suggesting that it will make no difference at all? Yes there is a riders technique that might need to be looked at, but go back to a bar/stem setup you used 15 years ago and I bet you wouldn't corner or ride the bike as well.

    Well i probaly wouldnt no, cause im still learning, but give it to a pro and either stem/bar combo and they will rail the corner

    The length of the stem would make little difference to the cornering action anyway. A shorter stem only speeds up the turning of the handlebars, and since railing a corner is all about leaning the bike underneath you, i doubt a longer/shorter stem would make that much difference. Although that said, stem length dies effect weight distribution, so i guess if you went too short you could unweight the front end, but that could easily be counteracted by taking a more aggressive position on the bike.

    Wider bars would probably make it easier/more stable to lean the bike, so i guess would make it "easier", but if you dont understand the mechanics of actually railing the corner, then i fail to see how having longer handlebars would make any difference. Its like giving a monkey a spaceship. Yes it can go into space, but unless you train the monkey to fly the thing, you may as well have given it a banana.

    The point im making is that shortening the stem a bit and putting wider bars on will not have as greater effect as learning to ride your bike properly

    I've just changed my bars from 680mm to 710mm cos I had a pair in the shed so I thought i'd give them a go....I don't think it makes any difference :?

    Whereas I recently went from 720s to 750s and I'd say it made a huge difference. Hands were sliding off the edges on the 720s.

    Stem and bar length can effect the way a bike handles and shouldn't be totally ignored but I would always look at technique first.

    As suggested there are many cornering guides that should hopefully sort you out. Search the big bike website like Bikeradar and Pinkbike etc.. and you'll find guides from professional riders or tutors that will show you the correct technique. Not some random kid on you tube :-)

    The bar width and stem combo can be a very personal thing, with some who don't get on with wider bars and actually prefer narrower bars. The sizes the OP states are still within modern tastes and if they feel comfortable I wouldn't bother changing them for now.

    And the answer is, your brain is concentrating too much on your entry and not enough on your exit. That's why you are making adjustments to your line.
