so i purchased a 2012 giant roam 1 from my LBS a few months ago. I absolutely love it. But i wanted to know what upgrades can i do? so far ive recently bought a bell platinum series led headlight and taillight combo. i know i went cheap with it. but i rarely ride at night. what performance parts can i upgrade? what accessories do you guys recommend getting? ie: racks, fenders, drop bars, suspension seat tower, pedal toe clips. thanks.
