Parcours’ updated Chrono wheels debut three new options from deep, to deeper, to full disc for riders looking for more speed without giving up crosswind stability.

The new Chrono wheelset is a mixed depth front and rear combo. They’re joined by the deeper Chrono Max front wheel, which can be paired with the all-new Chrono Disc² rear wheel. Despite being deeper than their predecessors, they windtunnel tested to be just as stable but now faster in a straight line.

They’re also designed and aerodynamically optimized for 28mm tubeless tires, giving riders the advantages of lower air pressures, better traction and more comfort without losing speed. Parcours Chrono Wheelset

Designed in collaboration with Nottingham Trent University and Dr. Steve Faulkner, the new range is built on their #thinkwider concept ( read the white paper here ). The goal is to provide the fastest possible wheels that can also maintain safe, predictable handling in crosswinds.

The TL;DR version is that they found that real world yaw angles differ by up to 1.5º from front to rear, so the rim profiles are different for front and back. A blunter U-shaped front rim profile handles steeper wind angles better, while a V-shaped rear rim slices through the air better at the lower yaw angles it sees.

The Chrono Wheelset uses a 68.6mm deep front wheel with a 75.7mm deep rear wheel. It’s the deepest combo they offer, aimed at racers, triathletes and time trialists who don’t want to go full disc in the rear.
