Dutch legend adds to extensive rainbow jersey collection in Leuven <\/p>

Newly crowned 2024 UCI Women’s Gravel World Champion Marianna Vos used the latest \u20ac3,898 Gravaa KAPS hub system for on-the-fly tyre pressure adjustment at this year’s event in Leuven, Belgium.<\/p>

Gravaa’s design, officially announced in July<\/a>, enables a rider to deflate and inflate their tyres using a bar-mounted remote during a race. <\/p>

Air, a battery and a small compressor are housed in each hub, with an airline running up a spoke.<\/p>

The hub is visibly bigger Liam Cahill \/ Our Media<\/span><\/figcaption><\/figure>

The system works using a clutch mechanism housed within the Gravaa hub.<\/p>

With the clutch engaged, the system pumps up the tyre using the rotational movement of the hub via a tube attached to the spokes. Gravaa says that the system adds less than 250g per wheel.\u00a0<\/p>

Speaking to BikeRadar before the race, Vos seemed unsure of when she would employ the system.<\/p>

“There are some tricky sectors and also quite a lot of tarmac so then it might be useful to use it but, of course, it also adds something in your mind, so maybe I will forget it.”<\/p>

However, the 3-time road world champion followed up by saying “I will try to remember it in the right sectors.”<\/p>

There were no surprises on the groupset front Liam Cahill \/ Our Media<\/span><\/figcaption><\/figure>

The Visma Lease a Bike rider lined up on her Cervelo Aspero 5 bike complete with a SRAM Red AXS 1X drivetrain. The setup is very similar to the bike she used at Paris Roubaix earlier in the year<\/a>.<\/p>

The team uses a range of components from within the Pon Holdings umbrella, with Reserve providing the wheels.\u00a0<\/p>

\"\"
These tyres would usually be the other way around Liam Cahill \/ Our Media<\/span><\/figcaption><\/figure>

Mounted to these is a mixed Dugast setup with both of the brand\u2019s TLR (tubeless-ready) tyres coming from the cyclocross range. <\/p>

Vos opted for a slightly peculiar setup, combining a grippier Typhoon<\/a> on the rear with a file-tread Pipisqualo at the front.<\/p>

Commonly, riders in cyclocross would use a more aggressively profiled tread on the front tyre, where grip is needed. The rear tyre would usually be the faster option to reduce rolling resistance.\u00a0<\/p>

The setup was seemingly the right one with Vos edging out Kopecky for the win in Leuven.<\/p> <\/body><\/html>\n
