As rise in the MTB? (Taken from BIKE magazine no. April 26-May 2011)

Who does the following sound familiar ?:
"Uphill, when the inclination is important, the two main reasons why you can not reach the top without putting your feet on the ground are that the front wheel to lift you up or the rear skid . How to avoid these two evils? "
Put yourself in the position and pedaling hard. If you wake up the seat in a very steep rise is likely that the rear wheel skid, so stay seated and warrant that most of your weight falls on the rear wheel, which is what gives you traction, and thus this may stick better the ground. If you sit far behind the front wheel wants to get up, so you lose control and you can not go up, so you must put yourself leaning on the edge of the seat. The greater the slope, closer to the end you'll have to sit. To keep control of the front wheel well to sit upfront, elbows and lower chest, trying to get the trunk is parallel to the ground. You have to put weight on both wheels and this is what you get with this flat position. Try pedaling with force but without being rude, trying to pull up with one foot while pushing down instead.
The moderate slopes, completely change technique, as the grip is not a limiting factor, cycling, seated, a position virtually identical to the standard position, but from time to stand up to time, especially in long hikes. When you stand up, do not make the mistake of leaving the bike vertical, sideways range has to be done to make better use of weight change that is made with the pedaling. As you take one foot down, you have to go tilting the bike to the opposite side. To learn you can make the gesture, pausing with each pedal stroke.
