Very fast, durable and stable carbon clincher wheels that look good too
Weight: 
1,590g
Vision Metron 40 Clincher wheels
8 10

I tested Vision's Metron 40 Tubular wheels last year, and came away impressed. The Metron 40 Clincher carbon wheels use the same wide and rounded carbon fibre rim, cost the same (£1,499) but at 1,590g, they're are 258g heavier. The clincher rim makes them far more usable for amateur cyclists and racers.

Like the tubular versions, these are fast and responsive wheels, and perform well in all situations, from long distance sportives to flat-out road races. The entire Vision wheel range uses a fashionably wide rim profile, first pioneered by Zipp and Hed, and which is now sweeping through the industry.

The rim measures a whopping 26.45mm at the brake track. The internal width is 17mm. That external rim width does mean you'll have to adjust the brake calipers on your bike to fit the wheels, and does mean wheel changes - say to a training wheel for daily use - require some brake adjustment. It's no biggie though.

The idea behind the wider rim is to offer improved aerodynamics and to create a rounded profile with rim and tyre as a whole, there's an almost seamless transition from the tyre to the rim. The wider rims also more accommodating of wider tyres. 25 and 27mm tyres go on there just fine, without the lightbulb effect you get when fitting wide tyres to narrow rims. Vision recommend a minimum of a 23mm tyre. I used a pair of 23mm Schwalbe One tyres for the test.

Testing aerodynamic products in the real-world, without access to a wind-tunnel, is far from easy and Vision don't provide any aerodynamic data. However, it's clear the wheels are very fast, even compared to some other carbon clinchers. It's noticeably easier to maintain higher average speeds compared to a box section aluminium clincher wheelset.

They also feel very responsive and quick to accelerate from a range of speeds, despite the slightly higher weight compared to the tubular versions. At 1,590g, they're within acceptable limits and compare well to many similar wheels, but they're outshone by the Spin K2 Carbone XLR38 carbon clincher wheels I tested some time ago. They weighed 1,465gand cost over £500 less too.

The Metron wheels have a nice level of stiffness, enough to resist brake rub when sprinting aggressively, even with the brake blocks set up close to the rims. There's a small measure of deflection if you really push them hard, but on most occasions it's undetectable and not enough to negatively affect handling. They're solid, making them ideal for bashing along potholed and cobbled roads, and they even feel quite compliant over rougher surfaces.

Everywhere though, the wheels feel sharp, direct and fast through corners, from tight criterium-style bends to fast open sweepers. One of the really noticeable benefits of the rounded rim shape is stability in a range of wind conditions, you certainly don't need a wind-tunnel to test that out where I live, it always seems to be windy. In a strong crosswind the bike remained stable, with little buffeting, at low and high speeds.

The supplied Vision branded SwissStop brake blocks provide decent braking performance in the dry, an equal to other carbon rims. In the wet, well they're just as bad as most other carbon fibre wheels, and caution needs to be taken when attempting to stop quickly. This is a complaint I can level at most carbon wheels I've ever tested.

Hubs are as important as the rims of course, and there's been no shortcuts here. They feature a carbon-wrapped front hub, with both hubs centered around a large 17mm axle and spinning on ceramic bearings. The freehub accepts a 10 or 11-speed Shimano cassette - a Campagnolo version is available. You get a nice set of quick release skewers supplied in the box, along with some natty wheel bags.

The hubs have proven very reliable. They've been ridden through all weathers, had a hosepipe pointed their direction after most rides, and they're still rolling as smoothly as when they were first lifted out of the box. The hubs feature an adjustable collar to alter the bearing preload if necessary. The hubs do contribute to the great sensation of speed and silky smoothness these wheels offer.

The hubs are laced to the rims with 18 aero bladed spokes in the front wheel, 21 spokes in the rear wheel - seven radial on the non-driveside and 14 two-cross on the driveside. There are external brass nipples all round, so servicing is a doddle. The spokes have remained well tensioned through the test period too.

All things considered, the performance is impressive, and they tick all the boxes I look for in a high-end carbon fibre wheelset. They're fast and very responsive, and the hubs are a highlight with their ceramic bearings.

They're a worthy contender to the much more expensive Zipp 303 (£2,300) but there are some credible competitors closer to the £1,000 mark these days, such as the aforementioned Spin wheels which push the Metron wheels very close.

The Vision wheels have been raced at the highest level in the WorldTour, most notably by Peter Sagan, for the past couple of years. It's a top-level race-proven wheelset at a mid-level price.

Great wheels! I bought my set from a well known German web site and paid £849. Put Continental GP 4000 25mm tyres on them. Sweet!

Weight always seems a contentious issue with wheels - My set come in at 1562g with rim tape, which I'm more than happy with.

Speaking of weight, it would be useful if the wheel set reviews gave an indication of rider weight limits. You know, for those of us who aren't 67kg and have to consider such weighty matters (hohoho).

£1500 for a pair of 40mm wide profile clinchers that aren't especially light?

What do they actually offer over wheels that are 1/3 of the price?

I have these wheels on my Synapse with 25mm GP4000s and overall they are very pleasing.

These wheels are designed to run wider rubber for better performance and comfort at the cost of some extra weight, so testing them with 23mm tyres is not doing them justice.

Yup, no doubt! 1500 pounds for a pair weighing almost 1600 grams!
That's over 2k in usd...way over priced imo

I'll keep my 1486g/pair of 38mm Ekay composites that I paid $443 for.

Rims brake surface like the rims made in Taiwan,you know,DT Swiss clincher carbon wheels brake surface is like this,and DT Swiss many carbon rims are made in Taiwan just guessing.

how are they £1335 better than the Campagnolo Sciroccos I just bought which only weigh 200g more? That is a ridiculous £/g ratio

Very fast, durable and stable

As with all these reviews:
How much faster?
How much more durable?
How much more stable?
...and in comparison to what?

If you are resorting to this kind of hyperbole, you de-value the review process if you can't supply some actual figures or any kind of scientific or rigorous test procedure.

Campagnolo Sciroccos are amazing bang for buck. More than good enough to crit race on. The differences between them, Zipp 303s, Cosmics, Metron 40s and Reynolds Attacks are utterly minimal in my experience. Not that it stops me putting carbon wheels on my good bikes....

These wheels are very good indeed. But for £500 less you can get Miche's SWR Full Carbon RC wheels which are awesome. Don't take my word for granted and get them for a test ride on your LBS, you're going to be surprised.
