Why is Jumbo-Visma using unbranded wheels in this year’s Tour de France?

It was easy to spot the Jumbo-Visma team in the first week of the Tour de France 2020. So far, they have proven to be the dominant team in the race. The Dutch team won stages and a controlled tempo at the head of the peloton in support of the favorite of the GC, Primož Roglič. But what about those unbranded black wheels they use?

The search for marginal gains in professional cycling is nothing new. However, Jumbo-Visma was forced to look long and seriously for ways to reduce the weight of its Bianchi Oltre XR4 bikes, which came out in 2016, are no longer as thin as they were when they launched. Enter the “unnamed” wheels, used primarily on the team’s climbing machines.

The wheels are in fact the WS + tubulars from Corima. The reason for Jumbo-Visma’s stealthy approach? The team is under contract to drive Shimano wheels. In some ways, the lack of branding made the wheels more noticeable; particularly contrasted with the beige-walled Vittoria Corsa rubber they use. With Roglič, Wout van Aert and Sepp Kuss leading the race and taking up a lot of screen time, the wheels became a topic of discussion.

Corima wheels are lighter than all Shimano offerings, including its Dura-Ace C24 carbon model. It’s a matter of grams; the WS + are around 10 grams lighter than the C24s, but are significantly lighter than the Dura-Ace C40 wheels that Jumbo-Visma has fitted in previous races. Roglič and Tom Dumoulin have been seen pairing a Corima front wheel with a deeper Dura-Ace rear wheel, while some riders like Robert Gesink and George Bennett have opted for unbranded Corima wheels up front and down. the back. The wheels used with a few other weight reduction choices are starting to add up.
