Balance is the New Speed
Inspired by the philosophy of QianKun, we’ve created the perfect harmony of lightweight aerodynamics, high-rigidity rims, precision hubs, and aero carbon spokes. This synergy delivers a wheelset that is not only lighter, but also stiffer, faster, and more responsive than ever.
The result is the Qiankun CS Series — a race-ready wheelset starting at just 1185 g, giving every rider the competitive edge to climb, sprint, and push beyond limits.
Inspired by the philosophy ofQianKun, we’ve engineered the perfect balance oflightweight aerodynamics, high-rigidity rims, and race-level durability. At just375 g per rim, tested to withstand120 J impact standards, the Qiankun CS Series delivers the speed, stiffness, and strength every racer demands.
Lightest in Class 50mm Aero Wheelset
At just1185 g, the Qiankun CS50 is one of the lightest 50 mm aero wheelsets in its class. Built with T1000 carbon and carbon spokes, it delivers explosive acceleration on climbs while still slicing through the wind on the flats.

Testing Process
Rim Test
Rim Test
Qiankun rims undergorigidity and impact testingto prove both lateral and radial stiffness. Each spoke hole withstands forces up to600 kgf, ensuring durability under extreme racing loads without sacrificing lightweight performance.
Spoke Test
Spoke Test
Qiankun carbon spokes are individually tested to endure600 kgf of pulling forcewithout failure. The result ismaximum stiffness and instant power transfer, built to handle the most aggressive sprints and climbs.
Hub Test
Hub Test
Our hubs are pushed through atorque test of 230 Nm for 52,000 cycleswith zero damage, simulating years of real riding. Spoke holes are also tested at600 kgfto guarantee long-term strength and reliability.
Quality Control Test
Quality Control Test
All components come together in a wheelset proven to belighter, stiffer, and stronger. Every test confirms that Qiankun CS wheels are engineered to withstand the extreme forces of racing — delivering speed and reliability without compromise.
What makes the QianKun CS series different from NxT series wheels?
The Qiankun CS is Yoeleo’spinnacle race-focused wheelset, usingT1000 high-modulus carbon rimsandaero carbon spokesfor unmatched stiffness, responsiveness, and low weight. NxT wheels are excellent all-rounders, while Qiankun CS is designed specifically for riders chasingmaximum performance and race-day advantage.
How light are the QianKun CS wheels?
The CS50weighs just 1185g+/-3%, making it one of the lightest 50mm aero wheelsets available. The CS60 adds aero depth while remaining lightweight at 1285g+/-3%.
What riding styles are the CS50 and CS60 best for?
CS50:Perfect for climbing, all-round racing, and hilly courses thanks to its feather-light weight.CS60:Designed for high-speed racing, flat terrain, and sprint finishes where aero efficiency is critical.
