Algupära
The Protos was De Rosa's flagship competition machine through much of the 2010s — the top-of-catalogue race bike built entirely in the Milan workshop rather than outsourced to Asia. Using CM63 carbon, a proprietary blend developed with Japanese fibre suppliers, the Protos set De Rosa's benchmark for stiffness and weight before the Settanta (70) took the crown.

Verdikt
+Tugevused
- Exceptional stiffness and sprint response from CM63 ultra-HM carbon construction
- Milan-made craftsmanship with visible quality control at every weld and finish
- Race-geometry that rewards skilled aggressive riders over long days
−Nõrkused
- Very aggressive fit — short head tube limits accessibility for non-race riders
- Superseded by the lighter and more aero De Rosa 70; Protos is effectively a legacy platform
- 22 mm tubular spec on rim builds shows age — modern gravel and all-road demands have moved on
