And along the way you pick up tricks and a feel for it. First you have to relieve pressure on the chain. Then click. And most beginners don’t realize the click is directly linked to the cable, which is pushing on the chain… you can feel the chain through the clicker. Then gradually apply pressure as the chain engages the new gear, all the way back to full throttle. Ohhhhh man. That’s my favorite. And it all happens in a quarter of a second.
