At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The Merida Silex 200 is a slightly different take on a gravel bike in terms of geometry, but its more upright riding position is comfortable, and lots of exposed seatpost adds plushness. It has a quality frame and fork, although for the money the component list is a bit lacking compared with some tough opposition.

I wouldn't normally kick off a bike review by delving straight into the geometry, but it's kind of what really defines the Silex and separates it from the majority of gravel bikes on the market.

Most are based roughly on endurance style road bikes, but the Silex takes its design cues from the world of mountain biking, with a long top tube, a tall head tube and an increased fork length.

Looking at the geometry shows that the stack height (the height from the centre of the bottom bracket shell to the top of the head tube) of this medium model is 625mm, with a reach (the distance from the bottom bracket shell to the head tube, horizontally) of 400mm. Both are much bigger than you'd normally expect on a bike of this size.

Add in a 71-degree head angle and I was expecting some very relaxed/borderline sedate riding characteristics with sluggish handling. Merida has limited this, though, by speccing a short 80mm stem.

What I found was that the Silex is a very predictable machine, so if you have to cover some serious mileage, or want a bike that isn't going to be tricky or twitchy to ride on a changeable surface, the Merida is a good choice.

One thing I would say, though, is that at speeds below 10mph the steering can feel a little ponderous, a bit vague on some steep climbs or when negotiating tricky bits of singletrack compared with other gravel bikes I've ridden, but you soon adapt.

I also noticed, like Matt who reviewed the Silex 600 for, that because of the upright position it is quite easy to get the front wheel to pop up if you're riding aggressively on a climb.

Away from that, though, the Silex is a very comfortable machine to ride, especially over long distances. This is definitely more of an adventure bike than a gravel racer.

Being sat just that little bit more upright takes the pressure off the contact points and lower back, which on longer rides of four or five hours makes a big difference to comfort and efficiency.

The 1,060mm wheelbase gives a feeling of stability, and while the short stem increases the steering speed, it is still very neutral, so the Merida is also very easy to ride, especially so when you have bags attached for a bit of bikepacking.

The aluminium alloy frame delivers a pleasant ride feel, although with large volume tyres it's easier to mask any harshness than it is on a road bike.

Overall stiffness is good too – ideal for when climbing out of the saddle or if you want to get a move on, on the flatter sections.

When it comes to descending, the Silex handles well on all but the most technical of terrains. There are decent levels of feedback through the frame and fork, which allow you to feel exactly what the bike is up to beneath you.

The only thing that would really hold me back a bit on the downhills are the brakes. The cable-operated mechanism just doesn't offer the power or modulation of a hydraulic system or even a sorted rim brake calliper.

Frame and fork

The Silex Lite frame is made from 6066 series aluminium alloy, hydroformed to create the tube shapes.

2021 Merida Silex 200 - frame shape.jpg

The finish is decent enough – it's not the smoothest welding I've seen but it's okay, and covered well by a thick layer of paint.

Merida has chosen to go for a press-fit BB86 bottom bracket, which isn't going to be to everyone's taste for a bike that will spend its life predominantly off-road, due to the possibility of creaking if water and grit manage to get in between the mating surfaces. There have been quite a few wet rides on the Silex, though, and I haven't had any issues so far.

2021 Merida Silex 200 - bottom bracket.jpg

The Silex has mounts for three bottle cages, plus there are mounts on the fork legs too, so should you wish to go bikepacking, the Merida will carry a lot of kit securely. It'll also take mudguards.

Up front, the CF-2 fork is made from full carbon fibre and has a tapered steerer for increased stiffness under braking and steering loads. It copes with everything well, showing no signs of flex where you don't want it and, like the frame, has clearance for up to 42mm tyres.

2021 Merida Silex 200 - fork.jpg

As with the frame, it also uses flat mounts for the brake callipers and 12mm thru-axles for wheel retention.

2021 Merida Silex 200 - fork detail.jpg

For a clean look the Silex has internal cable routing through the front triangle before it exits beneath the bottom bracket. This means the mech cables leave the frame and get covered in all the mud and water being sprayed up from the front wheel, but Merida has sensibly run full outer cable housing right up to the mechs, which will keep them clean and running smoothly.

2021 Merida Silex 200 - cable route.jpg

The Silex comes in five sizes from XS through to XL, and as I said earlier, the geometry is a little different to what we are used to.

This medium has a 579mm top tube, 200mm head tube and a 500mm seat tube. It does have quite a steep seat tube angle at 74 degrees, but this aids climbing, putting you in a more forward position to get the power out.

I mentioned the stack and reach figures earlier saying how they are larger than expected, but for a bit of clarity it's worth remembering that other components come into play when it comes to your position.

2021 Merida Silex 200 - stem.jpg

Include the stem length and things are much more normal. My gravel bike has a 540mm top tube and a 160mm head tube which gives a reach of 382mm. Add my 110mm stem into the equation, though, and the distance to the handlebar from the saddle is pretty much the same.


The Silex 200 is based primarily around a Shimano Sora groupset – well, you are getting the STI levers, front mech and rear mech. Added to those are an FSA Omega chainset with 48/32-tooth chainrings and a Shimano CS-HG200 9-speed cassette that goes from 11 teeth up to 34.

2021 Merida Silex 200 - drive train.jpg

Personally, I prefer a 2x setup on a gravel bike and this is a decent spread of gears for me, giving suitable ratios at the upper and lower ends. Overall weight of the Merida is 10.45kg, so I didn't feel like I needed a massive bailout gear.

2021 Merida Silex 200 - cassette.jpg

Shifting from the Sora group is decent enough, mimicking that of previous editions of 105, but without quite as defined a click at the lever. It's not something you'll notice in isolation, though.

2021 Merida Silex 200 - Sora lever.jpg

The brakes are Promax DSK-330R and as I've mentioned they are cable operated. Unlike hydraulic systems that apply the pads from both sides of the calliper, these move from only one side which is a little disconcerting when you see how much the rotor flexes.

2021 Merida Silex 200 - front disc brake.jpg

Braking performance isn't that impressive, although it does get better once the 160mm rotors have seen a bit of bad weather and bedded in.

There isn't a huge amount of power there, and you don't get the levels of modulation that you do from more expensive systems. You can fettle around with the setup to get things just right, but it's an extra faff that you don't get with hydraulic calipers.

Finishing kit

The rest of the components are Merida branded.

The Expert GR handlebar is aluminium (as are all of the components) and has a shallow drop plus what looks to be about a 12-degree flare at the drops. This helps the handling on rough terrain, giving you a slightly wider stance.

2021 Merida Silex 200 - bars 1.jpg

The seatpost is 30.9mm in diameter and has zero set-back, the inline position adding to that steep seat angle to benefit climbing.

2021 Merida Silex 200 - seat tube junction.jpg

Saddle-wise, it's a Merida Comp CC. I got on fine with the shape, although the padding is a little too squishy for my tastes; we're all different in this respect, though.

2021 Merida Silex 200 - saddle.jpg

Wheels and tyres

The Merida Comp SL rims are just 17mm wide internally which limits their tyre compatibility; the 38mm tyres fitted here already look quite bulbous on them and will only get worse if you go to the frame's limit of 42mm.

2021 Merida Silex 200 - seat stays.jpg

They aren't tubeless compatible either, something I would like to see on a gravel bike.

They are tough, though, and while the rear was slightly out of true when the bike turned up, they haven't got any worse while taking on plenty of abuse from the local gravel trails.

Maxxis supplies the tyres in the form of its Rambler. A medium-level tread allows them to grip well on hardpacked surfaces and loose gravel. Like most gravel tyres, though, go anywhere near soft mud and you'll struggle.

Puncture proofing wasn't an issue, even with the tail end of the hedge cutting season leaving debris all over the local lanes. Should you find yourself on the road then they zing along pretty well and offer decent cornering grip too.


The £1,000 point is a very busy area in the gravel world, and I can't help feeling that the Silex 200 is a little under-specced for the money.

The Genesis CDA 30 is a bit heavier, but for the same money comes with Shimano GRX gearing mated to Tiagra shifters, which is a far superior setup than that found on the Merida.

For just £200 more you could go for the Merlin Malt G2X which is around the same weight but comes with a full hydraulic GRX groupset and tubeless-ready wheels. It has more tyre clearance too.


Overall, I like the ride quality and the geometry of the Silex, especially for those longer trips on the gravel. There is some tough opposition out there, though, and the Merida just doesn't quite hit the mark on the component front.

The front brake might work better if it were routed correctly.
