It used to seem that making a wheel for only one purpose was both acceptable and respectable. Climbing wheels had only one job -- to minimize spokes, shallow out rims, and pump up your tire pressure beyond sane numbers, so you could muster your way up HC-grade climbs. However, today, in a world of gear ratios that play kindly to knees and climbs, riders are asking for less drag, more aero, and furthermore -- wheels that transfer to smooth descents that don't leave our life flashing before our eyes as we rely on brake pads pressing against carbon through sharp corners on windy canyon descents. Zipp's tubeless 202 NSW Carbon Disc Brake Wheelset addresses both concerns by incorporating the aerodynamic features the brand built an empire on and adding the confident modulation of disc brakes. The better grip and more efficient rolling of tubeless tires also helps for climbing and descending, and the new freehub engages more quickly and freewheels with less drag. Better up, better down, better all the way around. We'll get to all of that tech below, but it's always appropriate to start with aerodynamics (or "speed weaponry") when discussing Zipp, and the signature Aerodynamic Boundary Layer Control (ABLC) dimpling returns with a new designation. It's called SawTooth Technology, and it consists of ABLC dimples applied in a single pattern repeated in 12 discrete swathes (or "nodes") across the rim's surface, looking much like the strokes of a paint brush. Zipp claims that SawTooth reduces side wind forces by "reducing the laminar bubble effect on the aerodynamically shielded side of the rim's profile." Translated into less technical terms, that means the rim's dimpling is designed to dispel the negative, drag-inducing force on the rim's non-wind side. SawTooth's premise stems from 42 computational fluid dynamics studies and testing that spilled out of the wind tunnel onto--gasp!--actual roads. In actual wind. You know, the conditions that we actual cyclists face every time .
