OK, I'm looking at a couple bikes for my wife, some have drum vs. standard brakes. What are the pros and cons? I don't think I like the drum breaks as much. For example CRF150 has tradititional breaks, but the CRF100 does not. I'm thinking the 100 because she will mostly ride on open dirt roads and small trails, so she doensn't need a MX bike, just something to zip around on and have some fun. I like the TTR as well, but I don't think it is as strong and sturdy enough for a few wrecks from a beginner.
