+1 ...For me, the riding I do and the terrain in which I do it, there's not much reason to be an early adopter. For me, give them a few generations to solve some issues, work out the bugs, make the solution more integrated and elegant, and re-assess. Of course, by then the rim-centric technologies may well have found some advances, too...
I agree that most caliper brakes have the power to lock both wheels. However, hydros offer must less effort to engage, like one finger. This can reduce hand fatigue on long decents. The "feel" or modulation of the brake is much better.When road riding I've NEVER been in a position where I felt I needed more/better braking power than I have with standard Ultegra or similar brakes.
And if I'm ever in that position the my first question would be should I be on something other than a light aggressive road bike.
Personally I think they are a solution to a problem that doesn't exist on the road. I totally get it for other types of riding but for road bikes on pavement I'll pass on hydraulics.
I agree that this could be interesting to say the least. I don't have carbon clinchers because I love my long decents around here. I don't want to worry about my tires blowing off.I can see disc brakes leading to advancements in rim aerodynamics. The heat, dimensions, and forces generated by rim brakes have been a limiting factor until now.
Sometimes crap happens...Not really sure how much this pertains to this thread, but i have a MTB with disk brakes which I use for the road. the other day while climbing a hill, I boke a spoke and the broken end wedged in between the disk and the pad locking up the wheel. almost catastorphic. with conventional brakes this will never happen. not sure if this has even happened to any one ever. just a thought.
