The Alex DA22 / Shimano Tiagra RS400 is a rear road wheel built for rim brake drivetrains, centered on the semi-aero Alex DA22 aluminum rim. The DA22 weighs 450 grams and balances aerodynamic shaping with lateral stiffness, while the Tiagra-grade RS400 hub delivers smooth cup-and-cone bearing performance with polished races for consistent rolling over daily road mileage.
Thirty-two stainless steel spokes laced with brass nipples provide long-term tension reliability and make truing straightforward when needed. The hub's cup-and-cone bearings are field-adjustable, and the 130mm QR axle fits standard rim brake road frames. The Shimano HG11 freehub body supports 8- through 11-speed cassettes, covering a broad range of compatible drivetrains.
