Protos

01

Origin

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.

The verdict

+Strengths
  • 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
Weaknesses
  • 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  • Superseded by the lighter and more aero De Rosa 70; Protos is effectively a legacy platform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
