Merida Reacto Disc 4000 2019 - Road Bike
Merida’s Carbon aero road bike with disc brakes. Lightweight and responsive using the slightly more relaxed geometry of their CF2 frame gives incredible stiffness to weight ratio with the advantages of an aerodynamic profile. The ride is more comfortable and better suited to longer days than the aggressive CF4 frames. Internal cable routing, Di2 ready and with a complementary component spec, the Reacto is ready to give you your fastest times.

We set out to create an incredible aero bike, but without the downsides often associated with the category such as harshness and complex solutions that waste workshop time.
The result was “astonishingly comfortable” (Design & Innovation award 2018) and describes as “fast and responsive” and “an absolute peach” (Road CC).
There is only 1 watt difference in efficiency between the calliper and disc brake version, very little sacrifice for the improved braking and extra wheel stiffness due to the 12mm bolt through axles.
The CF2 carbon frame has a slightly more relaxed geometry and more economic carbon fibre lay-up than the CF4. Tapered head tube, BB386 and 12mm bolt through axles for stiffness. Truncated NACA Fastback profile tubing for aerodynamics. Flat mount disc brake mounts with cooling fins, – 1150g M/L +/- 3%, fork = 420g
