Re: Finally not so lonely!
I live in hill country (Tennessee) and rim brakes stop me just fine. If you can afford disc brakes by all means get them. However I've hit down hill speeds over 45 mph and still had no problem being able to stop with rim brakes. As for coaster brakes they're fine for low speed stops but I personally wouldn't want to use them at speeds over 30 mph. You'll wear out your tires and be prone to skidding.
