2017 De Rosa Protos



The Protos design is truly revolutionary. Many other manufacturers are now trying to replicate the oversized downtube and compliance characteristics of this frame. Stiffness and power are of utmost importance in the world of competitive road bike racing and it is perhaps that, above all else, that truly captures the essence of Protos.

De Rosa made sure that they kept overall stiffness at the forefront of every design decision, but nowhere is this as evident as in the huge Protos down tube. The Protos tubes are oversized for maximum stiffness and constructed with a compilation of T800, T1000 and XN600. This combination makes for some of the stiffest and strongest carbon available. And it’s additionally woven with more flexible carbon in key strategic places. The result is massive power transfer for sprints and climbing but still comfortable for all-day riding.

The Protos includes a harmonic damping system in the rear to tame rutted roads. The chainstays and seatstays have a wide-narrow pattern that enhances comfort and drivetrain efficiency. All this makes for an unexpectedly smooth, comfortable ride.

The Protos frame is internally butted, removing the carbon internally where it isn’t needed. The resultant frame weight is only around 900g, so the bike can be built very light with the right components. Lightness and power are a magic recipe to win races, combine that with a good level of comfort and you have an incredible race bike.
