ULTRON 85 rear wheel
The most versatile wheel in our offer.
Super fast solution for every course and every condition
OTC profile
exceptional stability in challenging conditions
Thanks to its advanced aerodynamic design, the wheel remains remarkably stable and predictable even in strong crosswinds — especially considering its deep profile and high aerodynamic performance. Its optimized shape helps reduce sudden steering forces and improves control in changing wind conditions. This allows the rider to maintain confidence, speed, and an aerodynamic position even when conditions become demanding.
WIDE RIM. MODERN TYRE FIT.
With a 31 mm external width and 23.8 mm internal width, the ULTRON 85 is designed around modern wide tyres. The wider rim profile creates a smoother tyre-to-rim transition, supporting improved aerodynamics, stability and confident handling at high speed.
Built for every condition and every course
ULTRON 85 combines low weight, aerodynamic performance and confident handling. Its 85 mm profile delivers high-speed efficiency while remaining stable in changing wind conditions — from fast flats to technical and exposed sections.
