Origin

De Rosa introduced the Merak as the climbing-oriented counterpart to the aero-focused SK line. Its T800-dominant carbon layup delivers a frame claimed at just 800 g, while the stiff asymmetric chainstays and short 405 mm rear end bring a reactive, race-day feel suited to GC contenders and gran fondo enthusiasts.

The verdict

+Strengths

Exceptionally light frame (~800 g) delivers a lively, climbing-ready feel
Short 405 mm chainstays and asymmetric rear triangle produce sharp, direct handling
Wide groupset options (Campagnolo, Shimano Di2, SRAM AXS) cover all electronic preferences

−Weaknesses

Tire clearance limited to 30 mm — adequate but not generous for mixed roads
Price puts it firmly in premium territory against heavier competition from larger brands
Vertical compliance relies on seatpost flex rather than designed-in frame damping
