The size M test bike was a good fit for our test riders ranging from 1.78 m to 1.84 m, providing an aggressive yet not too stretched riding position. Previously, MERIDA used to designate intermediate sizes with “S/M” and “M/L” and hope to create more clarity with their new sizing model. Henceforth, their aero bike will also be available with a XXS frame and the designation of the individual sizes will change. Geometry and components of MERIDA’s latest road bikeįor the new REACTO, MERIDA have maintained the aggressive geometry of the previous model while making a few small changes. The Shimano Direct Mount derailleur hanger reflects the design of the Disc Cooler on the front and rear The look of the heat sink is reflected in the Shimano Direct Mount derailleur hanger, keeping the design and look of the bike consistent. While most modern high-performance disc brakes already have their own heat management systems, MERIDA see great benefits here, especially for lower-end brakes. The so-called Disc Coolers are designed to reduce the risk of overheating the brakes, especially on long descents. Another difference between the two frame levels is groupset compatibility as the CF5 frame is only compatible with electronic groupsets and the CF3 level frame allows for internal routing of both electronic and mechanical groupsets.Īs with the REACTO III and the SCULTURA ENDURANCE, MERIDA are relying on specially developed aluminium heat sinks between the frame and flat-mount brake callipers for their latest aero bike. axles) and the CF3 fork weighs 490 g (painted, uncut steerer tube, excl. The CF3 frame comes in at 1145 g (painted, excl. While the CF5 level frame, weighing approximately 965 g in size M (+/- 3% depending on the paint finish), and the CF5 level fork coming in at 457 g (+/- 3% depending on the paint finish) are considerably more complex in their carbon layup, the CF3 counterparts wheigh a little more but offer the same level of strength and stiffness. The main difference between the two frames is the grade of carbon fibres used and the time invested in developing the carbon layup. Both frames have the same geometry and, according to the manufacturer, should offer similar ride characteristics. The high-end models feature a CF5 level frame while the more affordable alternatives come with a CF3 level frameset. The new REACTO will only be available with disc brakes and a carbon frameset. The increase in clearance between the tire and the frame allows you to fit wider tires and is intended to guide airflow more efficiently Nevertheless, the designers claim to have managed to design the bike in such a way as to make it 1 watt more efficient than its predecessor, requiring 209 watts at 45 km/h. Not all features are conducive to aerodynamic improvement. You’ll find other modern standards such as 12 mm Thru-Axles front and rear as well as a PF86 bottom bracket, making the frame compatible with a wide range of components. For this purpose, the head tube has been enlarged and now features a 1½” to 1¼” headset. Integration was equally important when it came to the cable routing, as this is kept internal throughout, entering the frame via the Vision Metron 5D ACR cockpit. The standout features of the seat post are the integration of a rear light into the recess that gives the post its flex and the so-called Flip Flop head, which allows you to adjust the position of the saddle. The MERIDA S-FLEX seat post as featured previously on the REACTO III should also provide additional comfort on the latest model. So there is plenty of scope for those who want to tackle cobblestones or simply want a more comfortable ride. Similar to the recently introduced SCULTURA ENDURANCE, tire clearance is ample you’re officially allowed to fit tires up to 700 x 30C. The GPS mount has also been beautifully integrated and is compatible with all the common devices!īesides optimising the aerodynamics, the designers also wanted the new REACTO to be a fun and versatile bike. On the flagship models of the MERIDA REACTO, the cables are routed internally throughout the bike via the Vision cockpit. This should enable the rider to better utilize the sailing effect encountered in crosswinds. The so-called yaw angle has been increased and the frontal air flow has been improved with the help of Computational Fluid Dynamics (CFD) and tests in the wind tunnel. This was their priority in developing the new model and it should be significantly more streamlined compared to the REACTO III thanks to the fully integrated cable routing, a deeper seat tube, improved seat stay profiles and a new fork design. The much cleaner design of MERIDA’s fourth-generation REACTO compared to its predecessor is said to have come down to optimised aerodynamics. The concept of the brand new MERIDA REACTO
