Boom– I like disc brakes for road bikes because rim brakes rub through your carbon hoops over time, your wheel doesn’t have be completely true for them to work, and the extra power is nice. Maybe for racing it doesn’t make a ton of sense, but if you can’t replace your carbon wheels every year, disc brakes will add some durability
Trek is the #1 performance bike brand in the world. Our R&D department packs more engineering horsepower than any other bike company, and they're committed to making every one of our road bikes, from hand-built carbon race machines to refined aluminum models, the absolute best in its class. You'll feel the difference, from the first ride all the way to the podium.
i like hydro disc brakes on high end road bikes. now make the rims lighter(no need for extra material from rim brakes) and keep the weight closer to the hubs, down low for better handling. it’s a win win situation, unless you don’t like change for the good.
