Imaginative and prescient takes their aerodynamic highway wheels to the following degree with the brand new Metron RS racing sequence. Impressed through persisted good fortune at the International Excursion lately, and pushed through certain comments from their 2021 SL sequence overhaul, Imaginative and prescient continues to reinforce their degree of high quality and height pro-race functionality, whilst nonetheless holding pricing underneath many in their top-tier competition.
Those all-new Imaginative and prescient Metron 45 & 60 RS wheels mix confirmed aerodynamics with lighter and stiffer carbon spokes and smoother hubs to create a top rate aero wheelset with a hard-to-beat cost-to-performance ratio.
Imaginative and prescient Metron 45 & 60 RS carbon spoke aero highway wheels
Metron has at all times been Imaginative and prescient’s quickest, maximum aerodynamic highway motorcycle wheel line. However with the intention to conquer its traditionally sturdy place as a basically OEM logo, they’ve needed to push the envelope in creating upper functionality, lighter, stiffer, and better-performing wheels. For a logo referred to as the wheels that got here inventory for your motorcycle, Imaginative and prescient is combating demanding to turn they may be able to ship a wheelset worthy of upgrading and opting for over the likes of Enve or Zipp, for instance.
And those all-new carbon-spoked Metron RS wheels make a compelling argument.
So what’s new?
Lighter, more potent carbon spokes

That is Imaginative and prescient’s first complete carbon wheelset to mix carbon rims with carbon spokes.
The brand new RS (Racing Collection) wheels considerably reinforce on stiffness & reactivity because of the brand new carbon spokes. But additionally on the similar time, they shed numerous weight. Either one of those wheelsets are mild – underneath 1400g for the 60mm deep wheel, and underneath 1300g for the 45mm deep wheels.

The cause of switching the carbon spokes is a steadiness either one of weight financial savings vs. top rate bladed stainless-steel spoke (108 grams much less in line with wheelset), and likewise to extend the tensile power. The upper tensile power of the carbon spoke permits Imaginative and prescient to construct wheels with necessarily the similar rigidity, but create upper stiffness and extra reactive/responsive wheels.
The spokes are a complete UD carbon frame with a molded aero-bladed midsection, and on each and every finish an alloy interface with hub & rim. The ones alloy ends are held robotically in position with a tapered design that may’t separate. On the hub, they slot into a different T-head slot. On the rim, it seems like typical exterior nipples, however what you in fact see at the outdoor is that tooled alloy finish of the spoke’s threads. And also you in fact tighten/alter the spokes from inside the rim mattress by way of hidden inner nipples. No longer easy, however if you happen to injury a spoke, it’s replaceable rather simply.
New mid-depth aero rim profiles
The brand new wheels characteristic two new blunt-nosed aerodynamic rim profiles – 45mm or 60mm deep. Each are hooked tubeless-ready rims with 23mm inner width, and finally end up both 31.1mm large (45mm) or 33mm (60mm) on the widest level about 35mm clear of the spokes.
They’re designed for wider tires – minimal 28mm, however with aerodynamic functionality optimized for the 30 to 32mm vary that the majority professional groups want these days.
New PRS hubs, too
In addition they characteristic new PRS hubs, Imaginative and prescient’s personal ratchet-style hub with rapid 72-tooth engagement. However now the brand new V-1000 hub design is more practical than earlier than and doesn’t require gear to deal with or exchange the ratchets. The brand new wheels additionally step as much as complete ceramic bearings for lowered drag. And naturally, the hubs have that new proprietary straight-pull spoke interface for the T-head carbon spokes to forestall windup.
Progressed aerodynamic functionality
(Picture/Imaginative and prescient)
As for aerodynamics, Imaginative and prescient states that the brand new RS wheels have rather decrease drag than the former Imaginative and prescient Metron SL wheels of the similar intensity. Imaginative and prescient’s wind tunnel checking out presentations a 9% drag relief for the 45 RS vs. the 45 SL, and six% relief for the 60 RC vs. the 60 SL.
Trying out additionally unsurprisingly confirmed marginally upper facet drive as a result of the deeper carbon spokes. However in spite of everything, the variation was once minor, to the purpose that Imaginative and prescient chalked it up as imperceivable.
In spite of everything, the aerodynamic functionality of the wheels is moderately identical between the RS and the confirmed SL vary, however whilst now turning in a lot decrease weight and advanced lateral & torsional stiffness and upgraded responsiveness.
First Driving Impressions

I had a possibility to trip the brand new wheels on acquainted roads in Tuscany final week and so they’re undeniably fast feeling.
The large declare from the carbon spoke improve is combining greater than 100g of weight financial savings in line with wheelset whilst additionally bettering total wheel stiffness. The outcome being this simply noticeable light-weight really feel blended with harder-to-quantify enhancements in pedaling potency and faster acceleration.
At lower than 1300 grams, it indubitably seems like a light-weight mountain climbing wheelset whilst going uphill. However there doesn’t appear to be any pace compromise over rolling terrain or rapid descending.
The carbon spokes do additionally appear to lend a novel feeling to the wheels this is each aware of pedal enter, and but nonetheless is helping easy out little bits of highway buzz.
Apparently, it additionally felt just like the carbon spokes could have damped one of the most function noise you get from an aero carbon wheelset whilst using over textured asphalt. I used to be using the 45mm deep wheels – usually a quieter intensity – however I will be able to’t say I realized any deep carbon noise from the 60mm wheels of my pal using subsequent to me.
But talking of noise, the PRS freehub is loud when coasting. I for my part can recognize a humming hub. Loud hubs save lives, proper? However some could be eliminate through the loud whirr of coasting alongside. Worst case, you’ll be able to simply pedal tougher to lead them to quiet once more!
Imaginative and prescient Metron RS – Pricing, choices & availability
Imaginative and prescient Metron 45 RS
Those all-new carbon-spoked Imaginative and prescient Metron RS wheels are to be had now out of your native FSA/Imaginative and prescient store, in 45mm or 60mm depths.
Each are constructed solely through hand, characteristic molded-in (no longer drilled) spoke holes, and get low-key straight-out-of-the-mold glossy-on matte carbon graphics. (Shiny silver graphics are team-only.)
Metron 60 RS Crew Version
The brand new Metron RS wheels are no doubt dearer. They ratchet up the fee about 50% over the SL wheels to $2900 / 3110€ for the shallower 45mm rim, or $3000 / 3180€ for the deeper 60mm wheels.
