Vision Metron 60 SL Disc on test

The Vision Metron 60 SL Disc places its bets on full aero optimisation to trump the competition in our big aero wheel group test. But it’s not just the deep rims that promise to deliver. With in-house hubs and balanced handling, there’s no denying the Metron SL Discs racing ambitions. But does that come at the cost of too much weight?

Even though Vision wheels might not be the most popular as aftermarket upgrades, they’re firmly established in the professional scene, the most noteworthy being the EF Education EasyPost World Tour team. The EF Education pros have been riding Vision wheels for some time now. But have the wheels got what it takes to keep up with the competition in our group test? We put the high-end Metron 60 SL Disc wheelset to the test to find out. The 60 mm deep rims are paired with in-house components, allowing Vision to control every detail on their aero wheels. By the way, we recently got to visit Vision’s HQ and take a peek behind the scenes, which you can read about here.

Full aero – The specs of the Vision Metron 60 SL Disc

With the Metron 60 SL Disc, Vision decided to go all-in with aerodynamic optimisation. Doing so generally tends to come at the cost of weight. In fact, the 1,614 g wheels are about 200 g heavier than the test field average, and they’re the heaviest wheels on test by a significant 100 g margin. At € 2,209, however, they’re also at the lower end of the price range, making them the most affordable wheels on test. The wheelset includes a wheel bag, rim tape, loads of tubeless tape, and valves as standard, providing everything you need.

**Unobtrusive**
Da geht etwas mehr: Die schwarzen Logos sind zwar schick, doch im direkten Vergleich wirken die Vision 60 SL nicht ganz so edel.

**Down to the finest detail**
Vision are the only brand to integrate a raised and flattened valve port, making a tubeless setup really easy.

**Cool to see**
Rather than relying on a third-party manufacturer like some of the other brands in this test, Vision produce their own hub system.

The 60 mm deep rims themselves are perfectly matched to modern road tires, measuring 21 mm internally and 32.5 mm externally. The hooked rim flanges also provide added peace of mind and freedom of choice when it comes to the tires and pressures. Vision’s in-house Power Ratchet System hubs are equally promising, using a clever angled ratchet design that results in one of the loudest freehubs on test, on par with the HUNT SUB50. The look is less conspicuous: with a classic black carbon finish and glossy black decals, the wheels make a high-quality impression, though they can’t match the classy looks of the competition from Syncros and Reserve. Finally, Vision are impressively generous with their guarantee. Despite the comparatively affordable price, the Metron 60 SL Disc comes with a lifetime warranty and crash replacement.

**Innovative**
Vision develop everything themselves, relying on an innovative freehub design for the Metron 60 SL.

**Ready for anything**
The Vision Metron 60 SL Disc wheelset comes with traditional rim tape and tubeless tape included, allowing you to choose whether you want to run tubes or go tubeless.

Speed is king – The Metron 60 SL Vision on test

The handling of the Vision Metron 60 SL is characterised by it’s prioritisation of aero gains, and it’s clearly designed for racing at the pro level. Fortunately, that also means the wheels have been developed with long and difficult stages in mind. They’re not uncompromisingly stiff, like the wheels from HUNT and CADEX, offering enough compliance to make you feel relatively fresh even after 200 km. However, they’re by no means as soft as the Roval Rapide, resulting in responsive and fast wheels that perform well on the sprints and allow you maintain the pace. It’s here where the 60 mm deep rims excel. Once brought up to speed, the wheels spin with incredible smoothness and efficiency. Perfect for long straights, or the sprint on your home stretch. Unfortunately, this has a generally negative effect on their performance on the climbs. Due to their relatively high weight, they’re not the quickest to accelerate at low speeds.

Aero performance and results from the wind tunnel

Can wheelsets with 60 mm deep rims be slow? Perhaps, but the Vision Metron 60 SL Disc definitely isn’t one of them. The wheels feel like they’re amongst the top performers, both in terms of aerodynamics and the sail effect. This is confirmed by wind tunnel tests, clearly placing the Vision wheelset amongst the front-runners from Syncros, Roval, and Reserve. Although they’re slightly slower – about half a watt compared to the Roval Rapide CLX II – the Vision Metron 60 SL Disc still commands fourth place. It’s interesting to note that the Metron wheelset performs best at moderate yaw angles, up to around 12.5°, whereas Reserve and Roval excel at higher angles. So, depending on your aerodynamic philosophy and speed, Vision’s wheels can perform better – if you like riding into headwinds, then maybe these are the wheels for you 😉 .

Our conclusion on the Vision Metron 60 SL

The Vision Metron 60 SL Disc is an extremely capable wheelset that performs well in almost every respect. They’re well balanced and capable of excelling in a variety of situations. Wind tunnel tests confirm that they can keep up with the best, while showing a clear focus on lower yaw angles. It’s only on the climbs that they’re at a slight disadvantage compared to the lighter competition. Overall, it’s an excellent wheelset, especially considering the price.
