Just stumbled onto this website, Hope this is the right place to ask this question. Been commuting 13 miles round trip for several months on a trek 4300 hardtail mtb. Im aware this is rather dumb but when I bought the bike I didnt know that gas was going to be 4$ a gallon 2 years later. I dont want to spend the money to get a more road freindly bike. So I guess my best option would be to put slicks, I believe thats what they are called on to reduce the drag? I go mtb everyweekend so switching the knobbies and slicks out would get old really fast. I was kinda hoping some one could point me to a website where I could pick up two new rims and and cassette. Ive changed out my rear wheel before when I bent it or, tacoed it, but I dont know how to do much beyond that.

I dont really want anything amazing, Im just commuting but I dont mind spending a little extra so they dont bend the first time I have to hop onto a curb.

Id like to spend only 120? if I can do it cheaper awesome. I dont know much about what parts are good other than to stay away from walmart.

oh its a 24 speed bike so 8 cassetes in the back.

I appreciate any advice you guys may have for me. I apologzie if this is a repeat question, Ive browsed this forum for most of the day here at work and didnt find a section that seemed more apppriate.
