do a quick test on pavement with quality hydraulic (mech
) and compare to rim brakes. you're experienced...i am sure you already know. rim brakes stop, but not in as short a distance.
now you might argue mtb are used on dirt...fine, many times on a trail going down a hill into a turn etc etc there are times when your front will "driven" into the ground and you can give as much brake as you want. these are the times when disc brakes are nice...for agressive riding.
Sorry but I don't agree. A rotor brake doesn't stop me and my bike in half the distance of a V-brake (or even a canti). There might be a slight advantage but discs have twice the brake power of rims?? If you do an honest test, I doubt that you will find a modern linear brake that would need, for example, 50 feet to stop a bike while a disc could do it in 25 feet. Show me some data and I'll eat my words but discs just aren't twice as good as rims.
