Final night time (within the US), a picture popped up on the Cyclingspy Instagram web page exhibiting multi-disciplinary rider Wout Van Aert testing an uncommon setup forward of the Paris Olympic Time Trial. As a Visma–Lease a Bike rider, Van Aert can be driving a sponsor appropriate Cervelo P5 with Reserve wheels and Imaginative and prescient Metron TFE Professional P5 carbon extensions. Nothing has modified on that entrance.
The Cervelo P5 is a UCI compliant time trial bike. You gained’t discover any of the extra triathlon particular particulars like built-in hydration however it is likely one of the lightest TT bikes accessible. For Van Aert that appears to have gotten much more focus with a paired again, principally uncooked carbon, paint scheme. Most apparently although, the newest model of the P5 got here to market on the identical day as the primary time-trial stage of the 2024 Tour De France. The replace was modest, due to the UCI guidelines, however one of many adjustments was clearance for a large 34mm tire.
Van Aert is making use of that clearance with a Reserve model full disc wheelset with an exterior width of 38mm. Full disc wheelsets are uncommon in outside settings. The wind is a really efficient lever and meaning it’s at all times a danger exterior of a velodrome. Nonetheless, Paris appears to have calm wind circumstances up to now and there are some severe positive factors doable.
When requested for particulars, Reserve began by sharing that sure, the wheelset is out there on the market at a value of $4899. Regardless of that, it’s a “complete blue sky” undertaking designed “particularly for Wout for the Olympics, with the concept primarily based on the course profile and measured wind-conditions that he would POTENTIALLY use it.” If he had been to comply with by on that, the model famous that “Turbulent Aero undertaking” wind tunnel testing confirmed “there was a mean drag discount of 48.9 grams, or roughly 6 watts” in actual world circumstances. Wheel testing solely confirmed even bigger positive factors with “as much as -111 grams of drag for the disc at yaw.” To be clear, a damaging drag quantity is a sail impact.
For those who aren’t accustomed to the Turbulent Aero Mission, it’s all about replicating actual world circumstances. Reserve spent two years recording wind circumstances everywhere in the US on a motorbike outfitted with wind sensors. The staff then introduced that information again to the wind tunnel and used it to duplicate one thing past the sleek wind usually utilized in a wind tunnel. This information led Reserve to begin creating totally different wheels entrance and rear and wider wheels for wider tires. The Reserve Infinity Disc Turbulent Aero wheelset is uncommon not just for the truth that it’s a full disc entrance and rear but in addition as a result of it swells to 38mm within the entrance and 30mm within the rear. The inner width can also be unusually huge at 25mm entrance and 22mm rear making it doubtlessly “the one entrance disc on the planet designed for a 29c tire.” Reserve additional notes that “that is essentially inline with the general course” the model has taken for street wheels.
We’ll have to attend and see if this setup finally ends up seeing use and, if it does, will it’s the deciding issue that pushes Wout Van Aert to a gold?
