Just a recommendation, but the search function on this board works now, so you could use that:

Maybe the leg is what you aim for.
LuDawg: this is from wiki, better than i could describe in my own words
"In a gearbox with neutral between each gear, a typical shift actually involves two gear changes, once into neutral, and again into the next gear. During any shift, disconnecting drive components via a clutch properly unloads the engine and transmission of undue pressure applied by the opposing components. Fully utilizing the clutch for each shift out of, and then into each gear is double clutching. Due to the absence of a neutral spacing, double clutching is ill-advised for sequential gear changes, as in a fully sequential gearbox such as a sportbike.
Keeping the clutch pedal depressed while in neutral, as is performed during a typical shift, gives more economy of driver motion and effort compared to double clutching. Taken to extreme, sequential gearbox shifts and non-clutched shifts are also very quick and effortless. However, significant wear can take place on the separated clutch plates any time the engine and transmission have varying drive loads. In simple terms, wear occurs the more the clutch has to "slip" to match revolutions between the engine and transmission. Double clutching can minimize this clutch plate wear by encouraging matching of engine and transmission RPMs before the clutch plates are engaged."

Thanks for the info VAD!

Double clutching is a technique used when changing gears on an unsynchronized transmission. You use the clutch twice. Once for the shift to nuetral to unload the drivetrain and again when you place the gear selector in the next gear of your choice. With an unsynchronized transmission, this is virtually mandatory to reduce wear on the gears. Today only some commercial equipment still uses the simpler, more durable, unsynchronized gearbox.
However as you can see from the description, using the clutch twice is slower than using the clutch once. And, since every modern non-commercial transmission (cars) employs synchronizers and helical gears, there is absolutely no reason to double clutch. Unless you want to feel like a big rig driver.
