Looks can be deceiving, but it appears Mathieu van der Poel may have just leaked a new set of Shimano Dura-Ace gravel wheels. Pictured in a video by one of his training partners, Freddy Ovett, van der Poel was riding a Canyon Grail CFR gravel bike equipped with a set of wheels that dont appear to form part of Shimanos current catalogue. The obvious giveaway is the bold Dura-Ace branding, which hasnt been seen on Shimanos wheels since the R9100-generation models. Since we only have compressed screengrabs of Ovetts video to go on, theres only so much we can infer about this specific wheelset as things stand. However, given we know van der Poel and his teammates are testing other bits of prototype Shimano kit such as the carbon-spoked road wheels we spotted at Omloop het Nieuwsblad and a set of unreleased road pedals (the latter or which were partly to blame for taking him out of contention for the win at this year's Paris-Roubaix) this latest leak could signal something far more significant. Shimano may finally be ready to launch a flagship Dura-Ace gravel groupset. What we do and dont know so far The rims look a good match for van der Poel's gravel tyres. Freddy Ovett / Instagram So far, all we know for certain is that van der Poel is riding a different set of wheels, and that he and his teammates are currently testing new Shimano components. Of course, that doesnt mean this is a new set of unreleased Shimano Dura-Ace wheels, but it is a strong correlation. We can likely rule out van der Poel using a 10-year-old Dura-Ace R9100 wheelset, because Shimano only made 37mm- and 60mm-deep tubeless-ready carbon wheels for that generation and both had extremely narrow (by modern standards), 17mm internal and 24 / 28mm external rim widths. In contrast, the rims van der Poel is using seem to be a good match in terms of rim width and how the tyres are shaped for his chunky gravel tyres, at least from what we can glean from the video. Its possible van der Poel has simply badged up a set of wheels from another brand with Dura-Ace logos, to avoid prying eyes picking up on the fact hes gone rogue with his equipment choices. As with many pros, van der Poel has occasionally been spotted using non-sponsor-correct equipment over the years, after all. If Mathieu van der Poel is trying to hide something, he isn't doing a great job. Freddy Ovett / Instagram If that was the case, though, we might have expected him to pick some decals that were slightly more subtle and in line with existing Shimano wheelsets, rather than ones that look designed to be eye-catching. Shimanos existing gravel wheelset options top out with the 32mm-deep, GRX carbon wheelset so we can be fairly certain this isnt that wheelset with upgraded stickers. Its conceivable this is the same carbon-spoked road wheelset weve seen van der Poel race throughout this years spring classics, albeit finally badged up with sponsor logos. But given that wheelset is slated to have a 23mm internal rim width (according to the stickers we saw on the rims at Omloop), that still feels too narrow for a modern gravel wheelset even by Shimanos relatively conservative standards. Its existing GRX carbon wheelset features 25mm-wide rims, and wed expect any new gravel wheelset to be at least that wide. Is Dura-Ace finally coming to gravel? Sadly, we don't have enough resolution to decipher van der Poel's Haribo of choice. Freddy Ovett / Instagram If these wheels are the real deal, it could mean Shimano is planning to finally launch Dura-Ace-level gravel components. This would be a significant move for Shimano because its GRX series of gravel components has so far remained pitched steadfastly at an equivalent level to Ultegra Di2 and below. Shimano has a history of launching new technologies one step below the Dura-Ace level, before bringing them to its flagship component series later on, when it deems the technology to be sufficiently mature. Its first electronic/hydraulic road disc brake shifters the BR-R875s were pitched at the Ultegra level, before eventually reaching Dura-Ace with the R9100-generation groupset. A Dura-Ace gravel launch would make sense, too, given its now the only one of the big three groupset brands to not have a flagship gravel groupset, and the disciplines increasing commercial importance. Unfortunately, the potential leaks appear to end at the wheelset for now, because van der Poels Canyon looks to be equipped with a Dura-Ace Di2 R9200 road groupset. Weve contacted Shimano for comment and will update this article if we receive a response.
