The versatile, all-rounder that is the first choice for most race conditions.
Whether you are sprinting, attacking or climbing, the Black Fifty is the go-to-wheel for most conditions. The Fifty is optimal for everything except for the steepest climbs and the windiest of days. All our professional teams choose this model when they need a wheel that can do exceptionally well on the flat stages, that is also light enough to tackle the high mountain passes.
Our proprietary wide rim profile pierces through the air making it far more aerodynamic than narrower rim profiles. Our manufacturing process ensures that the Fifty has the most amount of possible compliance while being extremely laterally rigid. The Fifty is much faster than most other brand’s deeper section rims. This has been validated through in-house CFD optimization and confirmed in the real world through our collaboration with our pro teams and ex professional test pilots such as David Millar, Ryder Hesjedal and Baden Cooke.
With its unique rim profile, hand built with quality Sapim aero variable thickness spokes and alloy nipples, the Black Fifty is more aerodynamic, durable, comfortable and stable than any other aero wheel on the market.
