so I just got my first bike with gears and suspension. its a GT aggressor pro and all I can see now after I bought it is how limited it is for upgrading to fit somebody who will use it to cruise around but also handle some good trails. I wont be downhill or doing big jumps any time soon but having a capable bike to have fun and not fall apart. Im thinking I may need an upgraded fork and would be nice to have a derailluer with a clutch. any recommendations would be appreciated.
