As far as tubes go, I actually think I'm still running the factory tubes - why replace them?



When I replaced my tires the spoke nipples had rusted badly. That rust was all over the tubes. I think it's good practice to replace the tubes when the tires are replaced. Although I don't think it matters about what tube you use. Of course it's like anything else, some guys will go to fists that one tube or another is better, sort of like oil or filters or gas or plugs. I think any tube that fits will do the job nicely (yes, even $10 Cheng Shins). I think most shops will not replace a tubed tire without replacing the tube.
You probably would want to get the rear with a 90 valve stem, but make sure you have it turned to the sprocket side just to make checking easier on the side stand.
