If you could make your bike faster without sacrificing anything, would you do it? Right now most of us are probably thinking, ‘duh, of course.’ Free speed without a catch? Why the hell not?
After spending some time with the minds behind Merida’s latest bike, that seems to be the general idea for the new Reacto III. After going back to the drawing board, their third generation aero road bike was developed for this exact reason – to make their riders faster without huge compromises in comfort, handling, or serviceability.
At this point, almost every manufacturer has some sort of “aero” road bike, which tend to be completely different models than their all-around road machines. And while the aero bikes may prove to be seconds or even minutes faster at the end of the day, many riders still reach for the standard road bike. With the new Reacto, Merida hopes to change that…
“Aerodynamics are only a part of the total package”
When aerodynamically focused road bikes first started popping up, we heard a lot of claims about their ability to cheat the wind, but not much else. Building a carbon bike out of large aero profiles tends to make for a pretty stiff bike, which would often result in a bike that wasn’t as comfortable comparatively to other road bikes.
Make no mistake, the new Reacto is more aerodynamic than ever, but Merida put just as much emphasis on the ride quality as they did tube profiles and drag numbers. The evolution of a concept that started with the second generation, the Reacto III CF4 includes new version of their S-Flex seat post that is most comfortable (and fastest) yet.
Starting with a slimmer profile overall, the “S-Flex window” below the seatpost head is longer to induce more compliance that can be felt at the saddle. In the window itself, carbon fiber has been removed and replaced with an elastomer insert that aids in comfort but also fills the void for improved aerodynamics. The result is a claimed 24% improvement in lateral comfort compared to the previous S-Flex design.
Just as important, the seat post is very simple to adjust with two side mounted allen screws and it’s also removable to make traveling with the bike easier. Available in two different offsets (15 and 25mm). The seat post is adjusted with a wedge system on the top tube, and the post includes a rubber gasket to seal the seat tube/post junction and storage for an internal battery.
