Disk breaks

I saw a news story about disk breaks coming to the road bikes. I ride a SS and I do use both breaks. I would think disk breaks would be good. I am 240lb and can ride 30- 40 miles an hour and I need some stopping power.

Do ant if you guys have a fixes or SS with disk breaks. Or what do you guys think of the new trend.?

I think disc brakes for road bikes are a solution in search of a problem.

That's because you don't ride 30-40 miles an hour.

I'm hoping that's downhill, or I need new Legs. (put that disc brake in front and hit it hard at 40 MPH going down hill and let's see what happens, don't forget to film it!)

30-40 mph? How big is the chainring on that singlespeed?

You can coast downhill on a single. A 50/13 at 130 rpm is 39 mph.

My disc brake equipped road bike is multi-speed. I often exceed 40mph on descents where the number of gears available wouldn't matter. I also ride on flat lands where even vintage rim brakes with ancient/hardened pads are adequate, so I understand the incredulity expressed by some toward disc brakes. In order for disc brakes to perform better than rim brakes, rotor size and pad compound need to be optimized for the application. There is more friction available on pavement than dirt; don't get the wrong idea from discs intended for cyclocross bikes. For your weight and speeds I suggest a minimum 180mm front disc (bigger is better) and be sure it has plenty of mass to handle heat. Wispy spidery rotors look neat, but don't perform as well as stout hunks of metal.

The bottom line is disc brakes are good, just as you imagined.
