Its widths are measured centre to centre in the drops; at the hoods they are 305, 325 and 345 mm, and only the 420 (345/420) and a newer 345/380 option (10° flare instead of 17°) meet the UCI cockpit rules in force since 2026. The frame also takes other MERIDA and FSA ACR cockpits.
Aerodynamics
Manufacturer aero claimsMerida says the CF3 frame matches the CF5 frame's aero performance and stiffnessTOUR magazine wind-tunnel standard (45 km/h, pedalling mannequin, varying yaw): 196 W for the REACTO ONE (197 W with the UCI-compliant cockpit), 202 W for the 10K and 203 W for the TEAM, versus 211 W for the REACTO IV TEAM
Testing method—Hundreds of CFD iterations, four wind-tunnel sessions, in-house and Zedler Institute lab testing, and a velodrome test to settle the handlebar shape and rider position
