Algupära

The Corum is De Rosa's steel artisan road bike, built as an explicit homage to Italian racing tradition. Using 18MCDV6 chromoly — a high-grade chromium-molybdenum-vanadium alloy — the Corum brings the lively, vibration-absorbing ride feel of steel in a design refined over decades of Italian road racing culture. The 30-size range and made-to-measure option mean no two Corums need be identical.

Verdikt

+Tugevused

18MCDV6 chromoly delivers the classic steel compliance and vibration damping prized by long-distance riders
Made-to-measure and 30-size range offer genuine fit flexibility unavailable from mass-produced brands
Repairable and long-lived — steel frames can be straightened and rewelded, unlike carbon monocoques

−Nõrkused

At ~1,700 g frame weight it is substantially heavier than De Rosa's carbon offerings — physics of material density
Limited to ~28 mm tyres on rim-brake version — narrow by modern gravel/all-road standards
Premium artisan pricing for a material that is cheap per kilogram — the value is the craft, not the steel
