De Rosa Protos Ultegra Di2 Bike

General Information

The Protos is the marquee frameset from the venerated Italian builder. This latest iteration is beyond anything De Rosa has made before-in over sixty years of building--and the kind of bike that influences an industry.

De Rosa has always had a reputation for making stage race bikes, stable, comfortable rides that you can ride all day every day for three weeks, and keep on going. The comfort is important because the less the bike beats you up, the fresher you are as the kilometers tick on. Here, the challenge was to decrease weight, increase stiffness and increase comfort while keeping to the kind of ride De Rosa is known for. The bike has a short front-center with a lower than common bottom bracket for fast steering and stability, making it at home whether it’s a tight crit or a hors category gran fondo.

The weight is 860g for a 50cm frame. Keeping the weight low was important, but not at the cost of comfort, stiffness, or ride.
