How to ride under obstacles Commuting by an MTB, there is a trail at the local park, that is partially blocked by a tree. It has fallen over the trail, forming a triangle with the living trees on the sides. The highest point is maybe 10cm higher than my saddle height.

How can I ride under the tree (at speed), without dismounting?

My best try has been tilting the bike severely to the side, and crouching onto the outside pedal. Still, I hit my backpack and fell. Other attempts have been even more miserable. What is the correct technique?
10 cm from the saddle would be possible if you are talking about XC saddle height and the handlebars are lower than the seat.

One way is to do this:



Another way is to bend and go very deep:


knees bend pointing outside
hands totally straight to the bars so your body moves backwards
back totally straight
position your body so the saddle goes exactly between your head and your left or right bicep (whatever works best for you)
