    Question Uni Commuter

    Hi guys.. I tried to search but ran out of words to try.. any suggestions?

    I've got a nice new roadbike but it's snowing here in Canada, for my uni commute it's about 10 miles, and I've got a walmart mountain bike (circa 1994 no suspension just a hunk of steel) i want to operate on. parts I want to replace via ebaying/LBS:

    Crankset double
    Front Derailleur Shimano 105 (ordered)
    Rear Derailleur Shimano 105
    Bar (need suggestions but most likely cheapos)
    Shifters: Sora or Tiagra
    New Chain 9speed

    Basically I'm pretty new to this but I think i can feel my way into assembling it. I just need to know if it's feasible because of the technicalities, like the stem and steer measurements etc.

    Since it's a wallmart-bike, it's a flat bar, and it doesnt' have a real stem, just one that fits the particular bar, and I'm not sure if it's connected to teh steerer. furthermore i'm not sure if conventional stems fit this steerer.

    Another question I would liek to ask is, they are generic brakes and derailleurs, the mechanics of it connecting to the road shifters are the same right? There won't be a compatability issue will there?

    Has anyone attempted this before or is this idea just stupid? I just want to try it out and I have a bit of cash to make it happen so any input would be greatly appreciated. Thanks

    ps, also, if i decided to replace the wheels I could put road wheels into them right? the grooves will hold both types? (theoretically)

    Sorry I can't answer any of your questions. I clicked on this thread because I thought it was going to be about someone commuting on a unicycle, and that I HAD to see. ;)
    Move along...nothing to see here.

    For the cost of all your new jewelry, you could buy a entry level roadie bike pre made-FWIW; if you want to go ahead-get Zinn & the Art of Road Bike Maintenance--it'll tell you most of what you need to know.

    thanks, but i could probably get the majority of those parts for less than 100$ off ebay, so thats why the idea came to me in the first place. I too think its time to buy that Zinn book.

    couldn't resist

    Maybe it's not stupid but it doesn't really make any sense. My parents have a bike similiar to the one you're thinking about fixing up. The got it from a casino promotion. It's new except for a couple miles I put on it. Of course being a tinkerer I've thought of doing something with it. The main problem with the bike is that you can't stop it. The calipers are really cheap, the levers are plastic and the rims are chromed steel and wildly out of true. My thoughts would be to replace the rear wheel with a coaster brake wheel and either replace the crank with a single chainring cruiser crank or leave the original one on there.

    The problem is that a bike of this quality is just not worth putting any money into. Your bike probably sold for $80 USD when it was new. Your $100 would be better off put towards a decent used bike.

    That's what I thought too! Bugger that would have been great.
    Oh, uh, good luck. (they are probably gonna tell you to start fresh and not with that frame)

    Likely stupid but that is no reason to not do it.

    You always learn something from a bike project. Likely what you will learn from this one is that you can not make a silk purse from a sows ear.

    BTW the only way you can put road 700C wheels in a 26" wheel ATB frame is if both sets of wheels have disc brakes. Otherwise the frame mounted rim brakes do not usually have enough range of brake pad adjustment to work on both sizes of rim.

    Sounds like you have a nice project to get you through the winter. Let us know how it works out for you.
