云鹏单车 无钩车圈303 Firecrest Carbon Tubeless Disc-brake

Zipp的303 Firecrest无管盘式制动轮对是为现实世界的…而设计的。一个条件不完善的世界，道路表面和要素，其中的底线是简单的。效率=速度它是更快，更轻，更有能力在不同的地形-无论表面是路面的所有条件，或根本没有路面。深深根植于齐普征服春天经典的动力，新303 Firecrest是重新设计了一个有目的的方法，以满足现代道路自行车的需求。说到骑自行车跑得快，效率就会降低：风阻，滚动阻力，骑手疲劳，重量。303 Firecrest无管式盘式制动器的设计使用了真实世界的直接测量(相对于主要是风洞或计算机模拟)。结果是巨大的。它的轮辋在设计上比它的前身略多一些，外部宽度为30毫米，内部宽度为25毫米，边缘深度为40毫米。该外形提供了低阻力和改善轮辋和轮胎之间的过渡，提高了道路上的空气效率。宽轮辋立场还具有较少的轮胎偏转，以减少滚动阻力。更宽的轮胎、增加的轮胎体积和较低的轮胎压力的组合有助于通过在不完善的路面和道路条件下的平顺来减少骑手的疲劳--轮胎和车轮系统吸收振动，而不是骑手。在中心的303 Firecrest无管式盘式制动器是一个多用途和耐用的新抱抱，德国工程ZR1 DB。这个集合功能66个点的接触，以更快的反应。303 Firecrest无管式盘式制动轮对是专为追求最新技术的自行车爱好者而设计的。其竞争对手…在种族中，对抗同龄人，或者仅仅是征服个人的极限。这是关于变得更快，并使你的动机与最先进的技术相匹配。

Zipp’s 303 Firecrest Tubeless Disc-brake wheelset is designed for the real world… a world of imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It’s faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp’s drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced: Wind resistance, rolling resistance, rider fatigue, weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. At the center of the 303 Firecrest Tubeless Disc brake is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless Disc-brake wheelset is for dedicated cyclists who aspire to the latest in technology. Its competitors… in races, against peers, or simply conquering personal limits. This is about becoming faster and matching your motivation to the most advanced technology.
