This is a low-speed skills used rolling down steep transitions (wheels on the ground). It could be used for a rock step, the back side of a pile of logs, or any other steep change in grade. This is a low-speed maneuver and differs from riding over a log, jumping or dropping. In this skill, your intent is to keep our wheels on the ground by rolling down the obstacle.
In a proper ready position approach the steep transition at jogging or walking speed with even weight on the pedals. Look at the top of the obstacle as you approach. Stay relaxed in your ready position.
2. Roll Up
If the transition has a step up (log, rock, root, etc.) at the front, be sure to lighten the front wheel to transition up the rise (slight lift of the bars, but keep the front wheel on the ground). If the transition has a smooth run-up this isn’t required.
As you reach the top of the transition, bring your weight forward so you can see what’s on the other side. This is your chance to bail-out if you choose not to ride down the transition. If you choose to bail out, apply your brakes and put a foot down.
At the exact moment your front wheel starts to roll over the transition, EXPLODE your handlebars down and forward. This quick explosion will push the front wheel forward and down the back side of the log over while simultaneously allowing your weight to go back behind your saddle. This explosion ensures your wheels evenly weighted as your transition down the back side of the transition. As you push your arms forward the seat will come forward under your belly.
Note: Do not pull up on the bars, you want the front wheel to stay in contact with the ground for the entire transition.
Keep your arms extended, un-weighting the handlebar to limit compression and to maximize a smooth front wheel roll out from the transition.
5. Roll Out
As your rear wheel transitions down the backside, bring your weight forward in order to maintain even weight on your both wheels.
Note: If you stay in the aft (exploded) position, the bike is likely to loop over backwards – or you may keep the front wheel down, but will have drastically diminished directional control.
Keep your head up — look ahead.
