Keystone, Dillion and Frisco are hard core mtb areas but still have great road riding. These three "towns" are all near or on I-70 but I don't think you'll find any real road shops.
If you can get to Boulder, however...
I think the following shops ae jsut about all you will find though I'm not 100% positive.
