I just moved into a new apartment and found an old Huffy 10-speed in the basement. Though I haven't been seeking a frame for a fixed gear, this got me thinking finally starting a new project. Have some questions though...

Is the frame of the Huffy even worth saving? I'd obviously strip it and throw on a new wheel set. Paint it with a black theme and use it for various city riding. I've wanted something that is completely trimmed down and not have to worry about using 3 locks when riding to the grocery store. I'm basically just looking for a reliable beater.

I also have an old(er) Trek 1100 mountain bike I converted to a commuter but find myself riding my road bike more often. I'm might consider using that frame instead as its lighter but the geometry is obviously different. That, and I haven't checked the drop outs.

Is it reasonable to use either of those frames or should I just start hunting garage sales?

Thanks for any input.
