Rebound on your rear shock

The rebound dial is what slows your shock or springs extension after taking a hit. If you didn’t have rebound dampening, your rear suspension can buck you off the bike like a mechanical bull.

Too much rebound can result in your shock not being able to fully extend after taking a hit on a bump or jump. If your taking a bunch of hits your shock starts to what they call “pack�? and it pushing your shock in causing you to not have enough travel. It also makes for a harsh ride.
If you have too little rebound, your bike will bob like a pogo stick.

Here’s a tip, set your rebound as fast as your shock can take without it feeling too springy. If its too bouncy for you, then adjust it one click at a time. You’ll have to play around with it until you find what’s right for your riding style.
