Merida's 2021 Reacto Team-E road bike is a race thoroughbred that excels on flat and rolling terrain. The straight line speed, stiffness and handling are all brilliant, but the ride may be too firm for some.

I said in my first ride review that this is unapologetically a 'race bike,' and I'm sticking with that. Comfort is the last thing on the Reacto's mind, with the focus being entirely on speed. Kick the pedals round and the bike reacts with a surge befitting the superbike price.
Merida says that weight was one of the primary concerns when moving the Reacto to more of an all-round race bike and away from just an aero rig. At 7.5kg on our scales for this size small, there is still some room before you worry the UCI's 6.8kg minimum weight rule, but I'd say it feels plenty lightweight enough.
There are a couple of component changes you could make to bring that weight down, but we'll get to that later.
The low weight certainly helps get you up to speed, but the Reacto really reaches its happy place cruising the flatlands around 40kph and above. The new aero claims aren't massively impressive, but the Reacto was a fast bike already, so saving a whopping two watts because the cables are now hidden is just a little bonus.
Eventually in the Mendips, you do have to climb a hill or two, though admittedly, I aim for them. Climbing really isn't a problem on these more 'modern' aero bikes. The Reacto feels light and climbs just as hard as you want to go.
In fact, I was dead impressed by the Reacto on the faster climbs or where the gradient levels out to around 4%. The Reacto really comes alive when you shift into the big ring, holding onto momentum very well.
A notable ride feature I mentioned before is how stiff the Reacto is, particularly the rear end. While a little messing around with tyre pressures led me away from my initial observation that the rear end was harsh, it's still a bike that focuses far more on putting your power onto the road than about giving you a comfortable ride.
Most of my riding has taken me around the roads of Somerset and the majority are surfaced with that lovely gravel dressing. As a result, any stiffness is magnified and usually felt through my hands, feet and posterior. I have been feeling those roads far more on this bike than on others. My Specialized Venge certainly feels smoother, though I still wouldn't call it a comfortable bike.
The Reacto isn't harsh, but you should know what you're getting into. Merida designed this as a full-on race bike and while they may have worked to increase comfort, it is still a single-minded speed machine.
Despite the high stiffness that can sometimes result in rather jittery cornering, the Reacto is very impressive when you really push it through the bends. The long and low position helps you get your own centre of gravity low, load the front tyre and carve through turns.
The single-minded speed machine description extends to the geometry, but the long and low position is perfect for this bike, helping you get as aero as possible. I am young, quite flexible and used to riding race bikes so the position wasn't an issue for me. If you're looking for a bike for long, relaxed days in the saddle, though, this isn't it.
I really like the steep head tube and seat tube that combine to give the Reacto handling the feels very on-edge. It is certainly lively, with a tight wheelbase adding to the whip-sharp handling.
Overall you're getting what Merida says the Reacto is. It's a fast bike with loads of stiffness, direct handling, a decently low weight and just enough comfort to make longer days and rough roads doable.
Frame and fork
Merida uses its CF5 IV carbon for both the frame and fork, and they've been redesigned for this 2021 model.
The changes can mostly be found at the front where the cables now stay hidden from the wind, entering the frame behind the upper headset bearing. It's a very clean aesthetic and a move that most bike manufacturers have been making in the last few years.
Merida says the cable integration is more aero, but doesn't specify how many watts have been saved, so you'll have to make do with how nice it looks. Moving down a little, the fork crown now sits slightly deeper into the down tube, which Merida says saves two watts.
The seatstays have also been dropped slightly, but apart from that, the frame is very similar to the outgoing model.
That's not a bad thing though. The Reacto continues with the massive chainstay design that meets an equally chunky bottom bracket shell housing a BB86.5 bearing system.
There are upsides and downsides to this press-fit system. They are supposedly stiffer than a threaded one, but while you might not be able to tell the difference in stiffness, you can always hear a problem bottom bracket. Thankfully, the Reacto has been making no funny noises.
The seat clamp is neatly integrated into the top tube and the seatpost, which gave me a bit of a headache when the bike arrived, is behaving itself now. No more mallets have been employed.
The seatpost has a cutout designed to add compliance right under the saddle, and Merida uses this space for a small rear light. I found it a little useless, personally, as it was covered by my saddle bag. The light is also rather dim and runs on an AA battery, so don't expect it to last for hours.
While I wouldn't use it normally, it is at least a handy safety feature for when it goes dark faster than you expected. These past few weeks I've been caught out a couple of times and it has worked well enough.
The finishing touches of flat mount callipers and thru-axle dropouts are standard fare.
Shimano's Dura-Ace R9170 groupset brings together the exceptional shifting quality of Di2 electronics and the all-weather predictability of hydraulic discs. A lot has already been said about this groupset, and it's due an update soon, so we won't dwell on it. What I will say, though, is that the performance increase over Ultegra Di2 is marginal.
I've also been riding SRAM Red eTap AXS lately, and I prefer Shimano by far. There may only be a fraction of a second's difference in the shift speed, but it makes all the difference for me. That said, I'd urge you to try both systems if you can. Stu would give his money to SRAM, see which one works for you.
Interestingly – and this is one area where Merida has Specialized beaten – a Shimano power meter is included. This dual-sided design has had its faults but seems to be sorted now, and provides me with data consistent with that of the SRAM Red AXS power meter and my dual-sided 4iiii. While I can't comment on the overall accuracy, it's consistent, and I found it easy to set up once connected to a Garmin head unit.
The reason Merida has Specialized and Trek beaten here is that this build comes in at £9,000. That's still a huge chunk of change, but it's far cheaper than the equivalent bikes from the two American brands.
Attached to the brake calliper area are the disc coolers, two heat sinks Merida claim improved performance through better cooling. Personally, I haven't felt much of a difference during normal riding.
The rotors still catch a little after heavy braking and it is telling that the Bahrain Merida pros seem to have removed theirs. Or, strictly speaking, had the mechanics remove them.
There are better steps to improving your braking. SwissStop pads and in particular, their rotors, are a great upgrade. The rotors don't flex like the Dura-Ace rotors do, though they do add a little weight. They're quieter too.
Vision provides the integrated bar/stem in the form of the 5D. I absolutely love the 5D, finding the shape of the drops very comfortable yet secure for sprint efforts. The bar features a distinct forward swoop to the clamp area, giving quite a long reach that I found ideal for this long and low position.
There's absolutely no flex when ripping the bike from side to side in a sprint, yet this stiffness doesn't translate to a harshness on the hands. The 5D is also properly integrated and comes with all the holes required for Di2, making a tidy setup very easy to achieve.
Vision also provides the wheels, but I'm not so impressed with these. They're plenty fast enough when up to speed on flat roads, but the weight make them a little sluggish when accelerating, and hampers climbing performance too.
Dave Arthur reviewed the Metron 55 SL Disc clincher wheelset separately, and I have to say I agree with his findings. These are good, but not the best.
Much was made of the replacement to the GP4000S II, but Continental's GP5000 clincher tyres haven't blown me away.
Sure, they're pretty predictable in the corners and they do very well in the rain, but when you come from a 350tpi casing, three layers of 180tpi casing feels very dull.
I always like to end on a positive note and the Prologo Scratch M5 has been fabulous. It's the first saddle without an open central cutout that I've got on with, and despite several four-hour rides I've had no discomfort at all.
The shape is stubby with a slight contour from back to front. It's designed for riders who want to get low and it does its job perfectly, supporting me as I did my best to lay down the power.
The middle section is slightly softer, and the shell has just enough give in the wings to move with you a little.
I've already touched on value. The Dura-Ace Di2 Specialized S-Works Tarmac SL7 is £10,500, while the equivalent Trek Emonda SLR 9 is £9,700 and the Madone SLR 9 is £11,350. Amongst the latest aero race bikes, the Reacto represents a decent saving then, and does it with a very similar spec.
Each bike gets some form of aero front end, deep carbon wheels, Shimano's Dura-Ace Di2 groupset and the Dura-Ace power meter.

If you have this kind of money to put down on a superbike then I'd urge you to try each bike before making a decision. One is going to fit you best, allowing you to tuck down comfortably into an aero position, and despite all the aero claims, the biggest impact is still your body.
I've been incredibly impressed by the stiffness of the 2020 Reacto Team-E. Combine this with the race-orientated geometry and superb handling and you have yourself a brilliant race bike. I wouldn't call this the comfiest racer I've ridden, though, so if you ride rough roads or want a little bit of comfort, then you may wish to look elsewhere.
Very fast, very stiff and very fun to ride – the Reacto Team-E is an excellent race bike

Tell us what the bike is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?
"The king is dead, long live the king!" says Merida of the seemingly improved, not overhauled 2021 Reacto. Merida seems to suggest a move away from all-out aero to more of all-rounder, something that we're seeing a lot of recently.
Merida says it "will once again deliver tons of fun and begs you to ride fast – all the time."
"With a clean design, optimised aerodynamics, cockpit cable integration, tyre clearance for up to 30 mm wide tyres, the well-proven Merida S-Flex seat post for maximum comfort and – for an aero road bike – very lightweight frame, it offers everything a modern aero bike needs to bring to the table."

Overall rating for frame and fork
Tell us about the build quality and finish of the frame and fork?
The only issue I had was a temporarily stuck seatpost. A mallet soon sorted the problem and it is now behaving itself.
Tell us about the materials used in the frame and fork?
Merida's CF5 carbon for the frame and fork.
Tell us about the geometry of the frame and fork?
It is long and very low – the perfect recipe for a race bike and I absolutely love it.
How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?
I found it very comparable to my S-Works Venge. It's long and low, so you should know you're buying an unapologetic race bike.
Was the bike comfortable to ride? Tell us how you felt about the ride quality.
The ride treads a thin line between stiff and a bit harsh. If the roads are mostly good in your area, you'll be fine.
Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?
There's no chance of this being too flexible. If anything, the rear kicks a little harshness through.
How did the bike transfer power? Did it feel efficient?
Stamp on the pedals and you move forward very quickly. The bike transfers power exceptionally well.
Was there any toe-clip overlap with the front wheel? If so was it a problem?
Yes, but I expect that with a race bike with a tight wheelbase. It isn't a problem.
How would you describe the steering? Was it lively neutral or unresponsive? Very lively.
Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?
I have been massively impressed through tight corners.
Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?
I would have liked some supple tyres. The GP5000 tyres feel very dull.
Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?
That Vision 5D bar/stem isn't budging at all. It is excellent.
Which components had the most effect (good or bad) on the bike's efficiency? would you recommend any changes?
The weight of the wheels means acceleration from low speed isn't great. Climbing on steep gradients is a bit slow too.

Ultegra Di2 is tiny bit heavier, far cheaper, and gives essentially the same performance.
Tell us some more about the drivetrain. Anything you particularly did or didn't like? Any components which didn't work well together?
Dura-Ace Di2 shifting and hydraulic brakes are brilliant – I far prefer this system to SRAM. The Dura-Ace disc rotors aren't my favourites, though. They're a bit flexible and can rub quite easily.

This is where I would make my first change. They're just a bit too heavy for the depth. Roval's new Rapide CLX wheels look very good, but Hunt's Aerodynamicist hoops would get my money.

It's a great race bike, very stiff, will suit bigger riders and handles brilliantly. There are still a few spec changes I'd make and it can be a bit harsh on tarmac that isn't perfect, though, so it's an eight.
