Shimano's flagship wheelset WH R9370 just got a serious upgrade, and it's available now at Cycle Store Zurich.
THE NUMBERS
Just 1,302g for the pair — 159g lighter than the previous C50 generation
Carbon spokes for a stiffer, more efficient power transfer
50mm mid depth carbon rim tuned for aerodynamics without sacrificing climbing feel
Fully reworked hub architecture with serviceable cup and cone bearings, so individual bearings can be replaced instead of the whole hub
Tubeless ready, built for 28 to 30c tyres
PROVEN ON THE COBBLES
Mathieu van der Poel raced a prototype version of this exact wheelset to solo victory at Omloop Het Nieuwsblad and E3 Saxo Classic in 2026, powering through the Molenberg and the Muur van Geraardsbergen on his way to the win. What you can ride now is the same tech that helped take him there.
Low weight. Real stiffness. Serious aero. This is the wheelset for riders who don't want to choose between climbing and speed.
