    … As a beginner XC rider, when you gain confidence and speed, the top weight starts becoming a hassle when making tight quick turns. The safe angle of the bike in turns is much tighter and you run a higher risk of a washout or overshooting a turn. … But, I have found that it is enough to ease the ride and greatly reduce the top heaviness of my bike. Making it MUCH easier to turn quickly with less kissing the ground …

    Dotaz v diskusi:

    I don't see how 1/2 pound extra weight could throw you off balance when there's 100–200 pounds of human even higher on the bike.

    You are correct, as long as you are planted on the saddle. The moment you raise or hover, that weight point moves to the pedals (I should have been more specific). On trails, most turns over 5 mph would not work so well if you remain seated. With that said… Think of a baseball bat or louisville slugger. Imagine holding it at the grip end with one hand and trying to keep the heavy end pointing up while running. Then, turn the bat over and hold it by the hitting end with one hand and try to keep the grip end pointing up while running. It's the same bat, same weight. But it is significantly more difficult on your muscles to keep it balanced when the bulk of the weight is further from the pivot point of your wrist. In this case, the seatpost, saddle, handlebar are all weight that you are pivoting from the point your tires are in contact with the ground. It is true that if you put your hand under the end of the bat, the opposite is true. It's easier to balance then with the heavy end up and lighter end down. However, that is not representative of riding because you are pivoting the base (or ground). However, if you could move the ground under the bike while you ride to counter the movement of your bike, it would be easier to keep it balanced.

    Vážně těžkej vršek respektive výše těžiště hraje až takovou roli, že si kvůli tomu lze nabít držku?
