Well, I'm 73, and when it was time to get a new road bike to supplement my 18 year old Bianchi steel frame (I could never replace it!), I ordered a Co-op from REI that has a great carbon fiber frame, good components and rims, and hydraulic disk brakes. I was dubious about the brakes, since nobody else I know has them, but that has become one of the main reasons I love it. The brakes take much less pressure to apply and are smoother and more precise than the cable disk brakes or rim brakes on my other two bikes. Going down the Colorado hills seems safer - my rims won't overheat and pop the tire, and the brakes don't fade coming down the Colorado National Monument. And of course it can stop on a dime. Don't automatically reject new technology. Sometimes it's better.
