2019 De Rosa Protos Disk
The De Rosa Protos Disk represents the best of classic Italian racing bikes with the added advantages of modern advancements. This WorldTour race ready carbon fiber frame will offer you amazing performance with the extra braking power that disc brakes guarantee.
Made from a special mix of high quality carbons such as T800, T1000 and XN600, the Protos Disk has been designed to ensure that ultimate balance of comfort, performance and low weight. It is the climbing bike that sponsored professional teams will use because it is so light, well under 1 kilo, while it has also received the attention to detail in the carbon layup to allow for an un-jarring ride quality. It’s a serious bike for folks who really take their racing seriously, but will also offer the level of comfort to keep anyone happy who mostly enjoys just going out and riding a bike.
The level of stiffness and effortless acceleration certainly comes to the fore in those race situations. Just one look at the huge down tube will tip you off that this is a burly beast. In fact all the front triangle tubes are oversized to offer maximum stiffness, using their special mix of carbons to get the desired ride quality in all the right places. So they can make it laterally stiff to enhance each pedal stroke, while weaving in some vertically compliant carbon to provide the day-long comfort. The fork has been given special attention so that it will be sturdy enough to withstand the disc brake forces, while offering a vibration-mitigated ride so your hands won’t buzz following an afternoon’s ride on chip and seal roads. In addition to that, the Protos Disk 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.
De Rosa have cleaned up the internals of the carbon, essentially butting it so that all unnecessary material is removed. That helps reduce the weight, keeping the frame to about 900 grams in a medium size, and ensure that the ride characteristics are exactly what the designers intended. They have wisely stuck with an Italian threaded bottom bracket, keeping things easy to maintain and accessible to a wide variety of cranks.
With eight sizes, you will certainly be able get the right size bike for your stack and reach preferences. Including disc brakes in the set up will also guarantee that the De Rosa Protos Disk is the type of bike that will keep you on your training schedule even through the rainy season. With this combined level of performance and practicality, the Protos Disk is your perfect bike.
