hes not talking about the preload knob that wont budge...there is a bolt like fixture on the right side of the fork where a lockout function would be...your dart is just like mine...one preload knob...the dart in itself is designed for Entry level mountain bikers so it has basically just bare bones function. My advice is to beat the crap out of it...ride and ride hard...test your limits and your riding ability and riding preference...the dart is an XC fork but when you start learning what you have fun doing you will need to upgrade to a fork that accomodates your riding style...I had a dart 2 and after discovering that I had the most fun doing "all mountain" I upgraded to a fork that was better suited for all mountain riding.
