I ride a cheap mountain bike around because if it's the best locked and cheapest bike on the bike rack, no one is gonna steal it. My only problem is that it's a hard bike (no shocks), and the only thing I've added to it are lights, a seat, a cyclocomputer, a patch kit, a minipump, and a horn. I've also tuned it up and roughly fitted it using basic internet knowledge.
What I'm wondering is what else could I do to this bike to make it a bit better for commuting. i know there's some stuff that I need like fenders, a rear rack, and maybe some slicks, but are there any other modifications I (or any other forum members) might need to know about converting a mountain bike for city riding? modifications for performance or weight conservation are welcome
